Method Detail

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 class ResourceResolverSpi

engineResolveURI

public XMLSignatureInput engineResolveURI(ResourceResolverContext context)
                                   throws ResourceResolverException

This is the workhorse method used to resolve resources.

Specified by:

engineResolveURI in class ResourceResolverSpi

Parameters:

context - Context to use to resolve resources.

Returns:

the resource wrapped around a XMLSignatureInput

Throws:

ResourceResolverException

engineCanResolveURI

public boolean engineCanResolveURI(ResourceResolverContext context)

Method engineCanResolve This method helps the ResourceResolver to decide whether a ResourceResolverSpi is able to perform the requested action.

Specified by:

engineCanResolveURI in class ResourceResolverSpi

Parameters:

context -
