| <h1>C/C++ search</h1> |
| |
| <p>The CDT lets you search for language constructs in the projects in your |
| workspace or a working set for references to, declarations or definitions of, particular |
| elements.</p> |
| |
| <p>For information on:</p> |
| |
| <ul> |
| <li> Working sets, see <b>Workbench User Guide > Concepts > Workbench > Working sets</b></li> |
| <li> The Eclipse workspace, see <b>Workbench User Guide > Tasks > Upgrading |
| Eclipse</b></li> |
| </ul> |
| |
| <p>You can conduct a fully or partially qualified name search. Further |
| qualifying a search increases the accuracy and relevance of search results. The |
| sections below provide guidance on how to control the scope of your search |
| through the use of search delimiters, correct syntax, and wildcards.</p> |
| |
| <h2>What you can search for</h2> |
| <p>The table below lists the element types that you can search for and special |
| considerations to note when searching for a given element type. You can search |
| for some or all of the element types matching a search string that you |
| specify. If you choose to search for matching elements, all types, macros, and typdefs are included in the search.</p> |
| <table border="1" cellpadding="0" cellspacing="0" style="border-collapse: collapse" bordercolor="#111111" width="60%"> |
| <tr> |
| <td width="19%"><b>Element</b></td> |
| <td width="81%"><b>Note</b></td> |
| </tr> |
| <tr> |
| <td width="19%"> Class/Struct</td> |
| <td width="81%">Searches for classes and structs.<p>You can further qualify |
| the search by specifying "class" or "struct" in front of the name |
| that you are |
| searching for. Specifying "class" or "struct" also allows you to |
| search for anonymous classes and structures.</td> |
| </tr> |
| <tr> |
| <td width="19%"> Function</td> |
| <td width="81%">Searches for global functions or functions in a namespace |
| (functions that are not members of a class, struct, or union).<p>You can |
| specify parameters to further qualify your search. When specifying a |
| parameter list, everything between the parentheses should be valid C/C++ |
| syntax.</p> |
| <p>Do not specify the return type of the function.</td> |
| </tr> |
| <tr> |
| <td width="19%"> Variable</td> |
| <td width="81%">Searches for variables that are not members of a class, |
| struct, or union.</td> |
| </tr> |
| <tr> |
| <td width="19%"> Union</td> |
| <td width="81%">Searches for unions.<p>Anonymous unions can be searched for by |
| specifying "union" as the search pattern.</td> |
| </tr> |
| <tr> |
| <td width="19%"> Method</td> |
| <td width="81%">Searches for methods that are members of a class, struct, or |
| union.<p>Searching for methods also finds constructors and destructors. See |
| above note for functions.</td> |
| </tr> |
| <tr> |
| <td width="19%"> Field </td> |
| <td width="81%">Searches for fields that are members of a class, struct, or |
| union.<p>Searching for fields also finds enumerators.</td> |
| </tr> |
| <tr> |
| <td width="19%"> Enumeration</td> |
| <td width="81%">Searches for enumerations.</td> |
| </tr> |
| <tr> |
| <td width="19%"> Namespace</td> |
| <td width="81%">Searches for namespaces.</td> |
| </tr> |
| </table> |
| |
| <h2>How you can limit your search</h2> |
| |
| <p>You can limit your search to one or all of the following:</p> |
| |
| <ul> |
| <li>Declarations</li> |
| <li>References</li> |
| <li>Definitions (for functions, methods, variables and fields)</li> |
| </ul> |
| |
| <p>You can control the scope of the search by specifying which of the following |
| is to be searched:</p> |
| <ul> |
| <li>Workspace</li> |
| <li>Working Set</li> |
| <li>Selected Resources</li> |
| </ul> |
| <h2>Wildcard characters</h2> |
| <p>You can use wildcard characters to further refine your search.</p> |
| <table border="1" cellpadding="0" cellspacing="0" style="border-collapse: collapse" bordercolor="#111111" width="60%"> |
| <tr> |
| <td width="49%"><b>Use this wildcard character</b></td> |
| <td width="51%"><b>To search for this</b></td> |
| </tr> |
| <tr> |
| <td width="49%"> <samp>*</samp></td> |
| <td width="51%">Any string<p><b>Tip:<br> |
| </b> Use the character <samp>*</samp> to search for |
| operators that begin with *. See syntax examples in the table below.</td> |
| </tr> |
| <tr> |
| <td width="49%"> <samp>?</samp></td> |
| <td width="51%">A single character</td> |
| </tr> |
| <tr> |
| <td width="49%"> <samp>::</samp></td> |
| <td width="51%">Nested elements</td> |
| </tr> |
| </table> |
| <p><b>Tip: </b>Do not use wild cards between the brackets of a function or |
| method pattern. For example, the search |
| string <samp>f( * )</samp> is an invalid search that results in a search for any function <samp>f</samp> |
| because |
| the asterisk is interpreted as a pointer rather than a wild card.</p> |
| <h2>Syntax examples</h2> |
| <p>The table below provides syntax examples and an explanation for each example |
| to help you conduct an effective search.</p> |
