/**
*
* Description: This is the static weave ant task definition class that verifies the value of specified attributes and invokes
* StaticWeaveProcessor to weave classes.
*
* Usage:
*
* - Ensure the classpath contains all the classes necessary to load the classes in the source.
*
- The lib containing this weaving Ant task must be added into the classpath by using the -lib option on Ant command line instead of using the classpath attribute of the taskdef Ant task.
*
- Define weaving Ant task and Ant target by using following attributes:
* source - specify source location. In the default configuration StaticWeaveAntTask assumes the source contains the persistence.xml,if this is not the case, the location containing the persistence.xml must be explicitly identified by the attribute 'persistenceinfo'.
* target - specify the output location (either a directory or a jar).
* persistenceinfo - specify the location containing the persistence.xml. This is optional and should only be specified if the source does not contain the persistence.xml.
* log - specify a logging file. This is optional
* loglevel - specify a literal value of toplink logging level(OFF,SEVERE,WARNING,INFO,CONFIG,FINE,FINER,FINEST) The default value is OFF(8). This is optional.
*
- The weaving will be performed in place if source and target point to the same location. Weaving in place is ONLY applicable for directory-based sources.
*
*Example:
*
*<target name="define.task" description="New task definition for toplink static weaving"/>
* <taskdef name="weave" classname="oracle.toplink.essentials.weaving.StaticWeaverAntTask"/>
*</target>
*<target name="weaving" description="perform weaving." depends="define.task">
* <weave source= "c:\foo.jar" target = "c:\wovenfoo.jar" persistenceinfo="c:\foo-containing-persistenceinfo.jar">
* <classpath>
* <pathelement path="c:\foo-dependent.jar"/>
* </classpath>
* </weave>
*</target>
