Method Detail

getArchiveEntries

protected java.util.Map<java.lang.String,java.util.jar.JarEntry> getArchiveEntries(boolean single)

Description copied from class: AbstractArchiveResourceSet

Obtain the map of entries in the archive. May return null in which case AbstractArchiveResourceSet.getArchiveEntry(String) should be used.

Specified by:

getArchiveEntries in class AbstractArchiveResourceSet

Parameters:

single - Is this request being make to support a single lookup? If false, a map will always be returned. If true, implementations may use this as a hint in determining the optimum way to respond.

Returns:

The archives entries mapped to their names or null if AbstractArchiveResourceSet.getArchiveEntry(String) should be used.

getArchiveEntry

protected java.util.jar.JarEntry getArchiveEntry(java.lang.String pathInArchive)

Description copied from class: AbstractArchiveResourceSet

Obtain a single entry from the archive. For performance reasons, AbstractArchiveResourceSet.getArchiveEntries(boolean) should always be called first and the archive entry looked up in the map if one is returned. Only if that call returns null should this method be used.

Specified by:

getArchiveEntry in class AbstractArchiveResourceSet

Parameters:

pathInArchive - The path in the archive of the entry required

Returns:

The specified archive entry or null if it does not exist

isMultiRelease

protected boolean isMultiRelease()

Specified by:

isMultiRelease in class AbstractArchiveResourceSet

initInternal

protected void initInternal()
                     throws LifecycleException

Description copied from class: LifecycleBase

Sub-classes implement this method to perform any instance initialisation required.

Specified by:

initInternal in class LifecycleBase

Throws:

LifecycleException - If the initialisation fails
