Method Detail
-
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 public void setReverseLoader(boolean reverseLoader)
Deprecated.since 1.6.x. stop using this attribute- Parameters:
reverseLoader- if true a delegated loader will take precedence over the parent
-
getClasspath
public Path getClasspath()
- Returns:
- the classpath for this definition
-
isReverseLoader
public boolean isReverseLoader()
- Returns:
- the reverse loader attribute of the classpath delegate.
-
getLoaderId
public java.lang.String getLoaderId()
Returns the loader id of the class path Delegate.- Returns:
- the loader id
-
getClasspathId
public java.lang.String getClasspathId()
Returns the class path id of the class path delegate.- Returns:
- the class path id
-
setClasspath
public void setClasspath(Path classpath)
Set the classpath to be used when searching for component being defined.- Parameters:
classpath- an Ant Path object containing the classpath.
-
createClasspath
public Path createClasspath()
Create the classpath to be used when searching for component being defined.- Returns:
- the classpath of the this definition
-
setClasspathRef
public void setClasspathRef(Reference r)
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
public void setLoaderRef(Reference r)
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
protected java.lang.ClassLoader createLoader()
create a classloader for this definition- Returns:
- the classloader from the cpDelegate
-
init
public void init() throws BuildExceptionDescription 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
