<h1>C/C++ search</h1>
|
|
|
|
<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>
|
|
|
|
<p>You can search for:<br>
|
|
<ul>
|
|
<li>language constructs within:
|
|
<ul>
|
|
<li>projects in your workspace</li>
|
|
<li>selected resources from various views</li>
|
|
<li>working sets</li>
|
|
</ul></li>
|
|
<li>a working set for references to particular elements</li>
|
|
<li>declarations of particular elements</li>
|
|
<li>definitions of particular elements</li>
|
|
<li>references of particular elements</li>
|
|
</ul>
|
|
</p>
|
|
|
|
For information on working sets, see <b>Workbench User Guide > Concepts > Workbench > Working sets</b><br>

<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>
|
|
<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>
|
|

|
|

|
|
<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>

specifying "union" as the search pattern.</td>

<td width="19%"> Method</td>
|

<td width="81%">Searches for methods that are members of a class, struct, or

above note for functions.</td>

<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

<h2>Search results</h2>
|
|
<p>Search results are displayed in the Search view. You can sort your search by Name, Parent Name and Path. You can also repeat
|
|
your last search.</p>
|
|
|
|
<h2>Search Concepts</h2>
|
|
|
|
<h3>Declarations</h3>
|
|
<p>According to the ANSI C++ Spec, a declaration is a statement that “introduces a name into a translation unit or re-declares a name that has been previously introduced by a previous declaration.</p>
|
|
<p>All C/C++ search elements can be searched for declarations.</p>
|
|
|
|
<h3>Definitions</h3>
|
|
<p>Most declarations are also definitions; in other words, they also define the entity for they declare the name for. However there are some elements that can have separate definitions from their declarations.</p>
|
|
<p>For C/C++ search the following elements can be searched for definitions:
|
|
<ul>
|
|
<li>Functions/Methods – the definition is where the code implementation resides</li>
|
|
<li>Variable:
|
|
<ol>
|
|
<li>Extern – the definition is where the variable is initialized</li>
|
|
<li>Non extern - the definition of a variable is where it is declared </li>
|
|
</ol></li>
|
|
<li>Field:
|
|
<ol>
|
|
<li>Static fields - the definition of a static field is where it gets initialized</li>
|
|
<li>Non static fields - the definition corresponds to the fields declaration</li>
|
|
</ol></li>
|
|
<li>Namespace – the definition of a namespace is the same as its declaration</li>
|
|
</ul></p>
|
|
|
|
<h3>References</h3>
|
|
<p>By selecting references, C/C++ search will return all of the places the selected element is used.</p>
|
|
|
|
<h3>All Occurrences</h3>
|
|
<p>Selecting ‘All Occurrences’ in the Limit To section will result in a search for declarations, definitions (if applicable) and references for whatever element or elements have been selected.</p>
|
|
|
|
<h3>Any Element</h3>
|
|
<p>Selecting ‘Any Element’ in the Search For section will result in a search for all of the listed elements plus macros and typedefs.</p>
