| Interface IEvaluationContext</H2> |
| <HR> |

| </PRE> |
| |
| <P> |
| An evaluation context supports evaluating code snippets. |
| <p> |
| A code snippet is pretty much any valid piece of JavaScript code that could be |
| pasted into the body of a method and compiled. However, there are two |
| areas where the rules are slightly more liberal. |
| <p> |
| First, a code snippet can return heterogeneous types. Inside the same code |
| snippet an <code>int</code> could be returned on one line, and a |
| <code>String</code> on the next, etc. For example, the following would be |
| considered a valid code snippet: |
| <pre> |
| <code> |
| char c = '3'; |
| switch (c) { |
| case '1': return 1; |
| case '2': return '2'; |
| case '3': return "3"; |
| default: return null; |
| } |
| </code> |
| </pre> |
| </p> |
| <p> |
| Second, if the last statement is only an expression, the <code>return</code> |
| keyword is implied. For example, the following returns <code>false</code>: |
| <pre> |
| <code> |
| int i = 1; |
| i == 2 |
| </code> |
| </pre> |
| </p> |
| <p> |
| Global variables are an additional feature of evaluation contexts. Within an |
| evaluation context, global variables maintain their value across evaluations. |
| These variables are particularly useful for storing the result of an |
| evaluation for use in subsequent evaluations. |
| </p> |
| <p> |
| The evaluation context remembers the name of the package in which code |
| snippets are run. The user can set this to any package, thereby gaining |
| access to types that are normally only visible within that package. |
| </p> |
| <p> |
| Finally, the evaluation context remembers a list of import declarations. The |
| user can import any packages and types so that the code snippets may refer |
| to types by their shorter simple names. |
| </p> |
| <p> |
| Example of use: |
| <pre> |
| <code> |
| IJavaScriptProject project = getJavaProject(); |
| IEvaluationContext context = project.newEvaluationContext(); |
| String codeSnippet = "int i= 0; i++"; |
| ICodeSnippetRequestor requestor = ...; |
| context.evaluateCodeSnippet(codeSnippet, requestor, progressMonitor); |
| </code> |
| </pre> |
| </p> |
| <p> |
| This interface is not intended to be implemented by clients. |
| <code>IJavaScriptProject.newEvaluationContext</code> can be used to obtain an |
| instance. |
| </p> |
