| <h2>Indexes for the Java search</h2> |
| <p>The JDT search creates indexes for all the sources and the dependent JARs. As a JAR gets added onto the classpath, it is indexed. |
| This operation could take some time depending upon the size of the JAR. To improve the performance, one can pre-build the index and specify the index file for a JAR |
| when it gets added onto the classpath. This is only supported for JARs. |
| </p> |
| <h3> Generating the index </h3> |
| <p> An index can be pre-generated in the following ways:</p> |
| <ul> |
| <li> An API <b><a href= |
| "../reference/api/org/eclipse/jdt/core/index/JavaIndexer.html#generateIndexForJar(String,%20String)"> |
| JavaIndexer#generateIndexForJar</a></b>. |
| </li> |
| <li> A command line application <b><a href= |
| "../reference/api/org/eclipse/jdt/core/index/JavaIndexerApplication.html"> |
| JavaIndexer</a></b> |
| </li> |
| <li> An Ant task <b><a href= "../reference/api/org/eclipse/jdt/core/BuildJarIndex.html"> |
| eclipse.buildJarIndex</a></b> |
| </li> |
| </ul> |
| |
| <h3> Specifying the index </h3> |
| <p> The index can be specified as a <b><a href="../reference/api/org/eclipse/jdt/core/IClasspathAttribute.html#INDEX_LOCATION_ATTRIBUTE_NAME">classpath attribute</a></b> |
| of the library that is getting added. The index file has to be in a valid URL form. If the index file |
| is not found, JDT generates an index file and uses it for searches. |
