Method Details
-
hasCpDelegate
protected boolean hasCpDelegate()Check if classpath attributes have been set. (to be called before getCpDelegate() is used.- Returns:
- true if cpDelegate has been created.
-
setReverseLoader
Deprecated.since 1.6.x. stop using this attribute- Parameters:
reverseLoader- if true a delegated loader will take precedence over the parent
-
getClasspath
- Returns:
- the classpath for this definition
-
isReverseLoader
public boolean isReverseLoader()- Returns:
- the reverse loader attribute of the classpath delegate.
-
getLoaderId
Returns the loader id of the class path Delegate.- Returns:
- the loader id
-
getClasspathId
Returns the class path id of the class path delegate.- Returns:
- the class path id
-
setClasspath
Set the classpath to be used when searching for component being defined.- Parameters:
classpath- an Ant Path object containing the classpath.
-
createClasspath
Create the classpath to be used when searching for component being defined.- Returns:
- the classpath of the this definition
-
setClasspathRef
Set a reference to a classpath to use when loading the files. To actually share the same loader, set loaderref as well- Parameters:
r- the reference to the classpath
-
setLoaderRef
Use the reference to locate the loader. If the loader is not found, the specified classpath will be used and registered with the specified name. This allows multiple taskdef/typedef to use the same class loader, so they can be used together, eliminating the need to put them in the CLASSPATH.- Parameters:
r- the reference to locate the loader.- Since:
- Ant 1.5
-
createLoader
create a classloader for this definition- Returns:
- the classloader from the cpDelegate
-
init
Description copied from class:TaskCalled by the project to let the task initialize properly. The default implementation is a no-op.- Overrides:
initin classTask- Throws:
BuildException- on error.- Since:
- Ant 1.6
