setTarget

public boolean setTarget(java.lang.String namespace,
                         java.lang.Object targetObject,
                         java.lang.Class targetInterface,
                         boolean overwrite)

creates an invocation target to match the incoming doc QName against each method name in the target interface and with the given NS.

Parameters:

namespace - the namespace of incoming doc to match

targetObject - the impl on which to invoke the method

targetInterface - the methods in the IMPL which are being exposed

overwrite - forces overwrite of existing target object and method with the same method name as one present in given interface.

Returns:

true if this was a unique mapping and no invokation target was overwritten -- i.e. no mapping NS+methodname combination already existed. false if there was already a target for the NS+methodname combination. If overwrite was false, this means that the operation was not performed.

Throws:

XsulException
