public class ResolverXPointer extends ResourceResolverSpi
Handles barename XPointer Reference URIs. To retain comments while selecting an element by an identifier ID, use the following full XPointer: URI='#xpointer(id('ID'))'. To retain comments while selecting the entire document, use the following full XPointer: URI='#xpointer(/)'. This XPointer contains a simple XPath expression that includes the root node, which the second to last step above replaces with all nodes of the parse tree (all descendants, plus all attributes, plus all namespaces nodes).

engineIsThreadSafe
public boolean engineIsThreadSafe()
Description copied from class:ResourceResolverSpi
Tells if the implementation does can be reused by several threads safely. It normally means that the implementation does not have any member, or there is member change between engineCanResolve and engineResolve invocations. Or it maintains all member info in ThreadLocal methods.- Overrides:
engineIsThreadSafe
in classResourceResolverSpi
-
engineResolveURI
public XMLSignatureInput engineResolveURI(ResourceResolverContext context) throws ResourceResolverException
This is the workhorse method used to resolve resources.- Specified by:
engineResolveURI
in classResourceResolverSpi
- Parameters:
context
- Context to use to resolve resources.- Returns:
- the resource wrapped around a XMLSignatureInput
- Throws:
ResourceResolverException
-
engineCanResolveURI
public boolean engineCanResolveURI(ResourceResolverContext context)
This method helps theResourceResolver
to decide whether aResourceResolverSpi
is able to perform the requested action.- Specified by:
engineCanResolveURI
in classResourceResolverSpi
- Parameters:
context
- Context in which to do resolution.- Returns:
- true if the engine can resolve the uri
