Constructor Detail

CachingPathResolver

public CachingPathResolver(PathResolver resolver,
                           org.apache.jackrabbit.spi.commons.conversion.GenerationalCache cache)

Creates a caching decorator for the given path resolver. The given generational cache is used for caching.

Parameters:

resolver - decorated path resolver

cache - generational cache

CachingPathResolver

public CachingPathResolver(PathResolver resolver)

Creates a caching decorator for the given path resolver.

Parameters:

resolver - name resolver

Method Detail

getQPath

public Path getQPath(String path)
              throws MalformedPathException,
                     IllegalNameException,
                     NamespaceException

Returns the qualified path for the given prefixed JCR path. The path is first looked up form the generational cache and the call gets delegated to the decorated path resolver only if the cache misses.

Specified by:

getQPath in interface PathResolver

Parameters:

path - prefixed JCR path

Returns:

qualified path

Throws:

MalformedPathException - if the JCR path format is invalid

IllegalNameException - if any of the JCR names contained in the path are invalid.

NamespaceException - if a namespace prefix can not be resolved

getJCRPath

public String getJCRPath(Path qpath)
                  throws NamespaceException

Returns the prefixed JCR path for the given qualified path. The path is first looked up form the generational cache and the call gets delegated to the decorated path resolver only if the cache misses.

Specified by:

getJCRPath in interface PathResolver

Parameters:

qpath - qualified path

Returns:

prefixed JCR path

Throws:

NamespaceException - if a namespace URI can not be resolved
