  <b>Purpose</b>: Define an object-level representation of a database query where clause.</p>
  <p>
  <b>Description</b>: An expression is a tree-like structure that defines the selection
  criteria for a query against objects in the database.  The expression has the advantage
  over SQL by being at the object-level, i.e. the object model attributes and relationships
  can be used to be query on instead of the database field names.
  Because it is an object, not a string the expression has the advantage that is can be
  easily manipulated through code to easily build complex selection criterias.</p>
  <p>
  <b>Responsibilities</b>:
  <ul>
  <li> Store the selection criteria in a tree-like structure.
  <li> Support public manipulation protocols for all comparison and function operators.
  <li> Use operator overloading to support all primitive types as well as objects.

 <div class="block">PUBLIC: Returns an expression equivalent to all of <code>attributeName</code>
  holding true for <code>criteria</code>.
  <p>
  For every expression with an anyOf, its negation has either an allOf or a
  noneOf.  The following two examples will illustrate as the second is the
  negation of the first:
  <p>
  AnyOf Example: Employees with a non '613' area code phone number.
  <blockquote><pre>
  ReadAllQuery query = new ReadAllQuery(Employee.class);
  ExpressionBuilder employee = new ExpressionBuilder();
  Expression exp = employee.anyOf("phoneNumbers").get("areaCode").notEqual("613");
  </pre></blockquote>
  <p>
  AllOf Example: Employees with all '613' area code phone numbers.
  <blockquote><pre>
  ExpressionBuilder employee = new ExpressionBuilder();
  ExpressionBuilder phones = new ExpressionBuilder();
  Expression exp = employee.allOf("phoneNumbers", phones.get("areaCode").equal("613"));
  SQL:
  SELECT ... EMPLOYEE t0 WHERE NOT EXISTS (SELECT ... PHONE t1 WHERE
                      (t0.EMP_ID = t1.EMP_ID) AND NOT (t1.AREACODE = '613'))
  </pre></blockquote>
  <p>
  allOf is the universal counterpart to the existential anyOf.  To have the
  condition evaluated for each instance it must be put inside of a subquery,
  which can be expressed as not exists (any of attributeName some condition).
  (All x such that y = !Exist x such that !y).
  <p>Likewise the syntax employee.allOf("phoneNumbers").get("areaCode").equal("613")
  is not supported for the <pre>equal</pre> must go inside a subQuery.
  <p>
  This method saves you from writing the sub query yourself.  The above is
  equivalent to the following expression:
  <blockquote><pre>
  ExpressionBuilder employee = new ExpressionBuilder();
  ExpressionBuilder phone = new ExpressionBuilder();
  ReportQuery subQuery = new ReportQuery(Phone.class, phone);
  subQuery.retreivePrimaryKeys();
  subQuery.setSelectionCriteria(phone.equal(employee.anyOf("phoneNumbers").and(
          phone.get("areaCode").notEqual("613")));
  Expression exp = employee.notExists(subQuery);
  </pre></blockquote>
  <p>
  Note if employee has no phone numbers allOf ~ noneOf.</div>

 <div class="block">Sets all tables represented by this expression to be queried as of a past
  time.
  <p>
  Example:
  </p>
  <pre>
   EclipseLink: employee.asOf(new AsOfClause(pastTime))
   Java: None
   SQL (Flashback): SELECT ... FROM EMPLOYEE AS OF TIMESTAMP (pastTime) t0 ...
   SQL (Generic): .. WHERE (t1.START  &lt;= pastTime) AND ((t1.END IS NULL) OR t1.END  &gt; pastTime)
  </pre>
  <p>
  Set an as of clause at the expression level to still query for current objects
  while expressing selection criteria like:
  <ul>
  <li>query objects as of one time that met some condition at another time.
  <li>query objects that changed a certain way over a certain interval (querying for change).
  </ul>
  <p>
  Simultaneously querying on two versions of the same object (one past
  one present) lets you express these advanced selection criteria.
  <p>
  Example: Querying on past attributes using parallel expressions.
  </p>
  <blockquote><pre>
    // Finds all employees who lived in Ottawa as of a past time.
    ExpressionBuilder employee = new ExpressionBuilder();
    ExpressionBuilder pastEmployee = new ExpressionBuilder(Employee.class);
    pastEmployee.asOf(pastTime);
    Expression pastAddress = pastEmployee.get("address"); // by default address will also be as of past time.
    Expression selectionCriteria = pastAddress.get("city").equal("Ottawa").and(
        employee.equal(pastEmployee));
  </pre></blockquote>
  <p>
  The advantage of the parallel expression is that you can still read current
  objects, the as of clause will affect only the where clause / selection criteria.
  <p>
  You may be tempted to rewrite the above as employee.get("address").asOf(pastTime).
  That is allowed but see below for the finer points involved in this.
  <p>
  Example: Querying on object changes using parallel expressions.
  </p>
  <blockquote><pre>
    // Finds all employees who recently received a raise.  Note that current
    // objects are returned, so can be cached normally.
    ExpressionBuilder employee = new ExpressionBuilder();
    Expression pastEmployee = new ExpressionBuilder(Employee.class);
    pastEmployee.asOf(yesterday);
    Expression parallelJoin = employee.equal(pastEmployee);
    Expression selectionCriteria = parallelJoin.and(
        employee.get("salary").greaterThan(pastEmployee.get("salary")));
  </pre></blockquote>
  <p>
  Example: Querying on object changes using custom query keys
  </p><blockquote><pre>
    // First define the custom query key and add it to your descriptor.
    ExpressionBuilder builder = new ExpressionBuilder(Employee.class);
    Expression joinCriteria = builder.getField("EMPLOYEE.EMP_ID").equal(builder.getParameter("EMPLOYEE.EMP_ID"));
    OneToOneQueryKey selfReferential = new OneToOneQueryKey();
    selfReferential.setName("this");
    selfReferential.setJoinCriteria(joinCriteria);
    selfReferential.setReferenceClass(Employee.class);
    getSession().getDescriptor(Employee.class).addQueryKey(selfReferential);

    // Now build query as before.
    Expression employee = new ExpessionBuilder();
    Expression pastEmployee = employee.get("this").asOf(yesterday);
    Expression selectionCriteria = employee.get("salary").greaterThan(pastEmployee.get("salary"));
  </pre></blockquote>
  <p>
  Note in general that any parallel expression can be rewritten using a custom query key.
  EclipseLink will even automatically interpret x.get("this") for you so you do
  not need to define the above query key first.
  <p>
  <b>Full Reference:</b>
  <p>
  If an object is mapped to multiple tables, then each table will be as of
  the same time.  Two objects mapped to the same table can not have different
  as of times.  Conversely only expressions which have associated tables can have an as
  of clause.
  <p>
  If an as of clause is not explicitly set an expression will use the clause
  of its base expression, and so on recursively until one is found or an
  ExpressionBuilder is reached.  Some usage scenarios follow:
  <ul>
  <li>employee.asOf(pastTime).anyOf("projects"): projects as of past time.
  <li>expressionBuilder.asOf(pastTime): entire expression as of past time.
  <li>employee.asOf(pastTime).anyOf("projects").asOf(null): projects as of current time.
  <li>employee.anyOf("projects").asOf(pastTime): projects only as of past time.
  </ul>
  <p>
  Watch out for x.asOf(oneTime).get("y").asOf(anotherTime).
  <ul>
  <li>emp.anyOf("phoneNumbers").asOf(yesterday) = emp.asOf(yesterday).anyOf("phoneNumbers") but:
  <li>emp.get("address").asOf(yesterday) != emp.asOf(yesterday).get("address").
  </ul>
  Whether the join is also as of yesterday depends on which table the foreign
  key field resides on.  In an anyOf the foreign key is always on the right, but
  in a get (1-1) it could be on either side.  For this
  reason employee.get("address").asOf(yesterday) is undefined as it can mean
  either 'my address as of yesterday', or 'my address, as of yesterday.'</div>

 <div class="block">PUBLIC: Returns an expression equivalent to none of <code>attributeName</code>
  holding true for <code>criteria</code>.
  <p>
  For every expression with an anyOf, its negation has either an allOf or a
  noneOf.  The following two examples will illustrate as the second is the
  negation of the first:
  <p>
  AnyOf Example: Employees with a '613' area code phone number.
  <blockquote><pre>
  ReadAllQuery query = new ReadAllQuery(Employee.class);
  ExpressionBuilder employee = new ExpressionBuilder();
  Expression exp = employee.anyOf("phoneNumbers").get("areaCode").equal("613");
  </pre></blockquote>
  <p>
  NoneOf Example: Employees with no '613' area code phone numbers.
  <blockquote><pre>
  ExpressionBuilder employee = new ExpressionBuilder();
  ExpressionBuilder phones = new ExpressionBuilder();
  Expression exp = employee.noneOf("phoneNumbers", phones.get("areaCode").equal("613"));
  SQL:
  SELECT ... EMPLOYEE t0 WHERE NOT EXISTS (SELECT ... PHONE t1 WHERE
                          (t0.EMP_ID = t1.EMP_ID) AND (t1.AREACODE = '613'))
  </pre></blockquote>
  <p>
  noneOf is the universal counterpart to the existential anyOf.  To have the
  condition evaluated for each instance it must be put inside of a subquery,
  which can be expressed as not exists (any of attributeName some condition).
  (All x such that !y = !Exist x such that y).
  <p>Likewise the syntax employee.noneOf("phoneNumbers").get("areaCode").equal("613")
  is not supported for the <code>equal</code> must go inside a subQuery.
  <p>
  This method saves you from writing the sub query yourself.  The above is
  equivalent to the following expression:
  <blockquote><pre>
  ExpressionBuilder employee = new ExpressionBuilder();
  ExpressionBuilder phone = new ExpressionBuilder();
  ReportQuery subQuery = new ReportQuery(Phone.class, phone);
  subQuery.retreivePrimaryKeys();
  subQuery.setSelectionCriteria(phone.equal(employee.anyOf("phoneNumbers").and(
          phone.get("areaCode").equal("613")));
  Expression exp = employee.notExists(subQuery);
  </pre></blockquote></div>

 <dd><code>criteria</code> - must have its own builder, as it will become the

  We are given an expression that comes from a different context than the one in which this was built,
  e.g. it is the selection criteria of a mapping, or the criteria on which multiple tables are joined in a descriptor.
  We need to transform it so it refers to the objects we are dealing with, and AND it into the rest of our expression.

  We want to replace the original base expression with (newBase), and any parameters will be given values based
  on the context which (this) provides.

  For example, suppose that the main expression is
       emp.address.streetName = 'something'
  and we are trying to twist the selection criteria for the mapping 'address' in Employee. Because that mapping
  selects addresses, we will use the 'address' node as the base. Values for any parameters will come from the 'emp' node,
  which was the base of the original expression. Note that the values need not be constants, they can be fields.

  We do this by taking the tree we're trying to merge and traverse it more or less re-executing it
  it with the appropriate initial receiver and context.
  Return the root of the new expression tree. This will probably need to be AND'ed with the root of the old tree.</div>
