All Implemented Interfaces:

CatalogEntry, Executable, Presentable, NamespaceContextFactory

public class ResourceAction
extends AbstractIdentifierAction
implements CatalogEntry

At runtime, the <cat:resource> element is used to test if an identifier matches a resource identifier. See $cat:resource and $cat:selector.

                      AbstractAction parent)
               throws XPathException

Creates a new instance of ResourceAction.

Parameters:

name - The name of the resource to match.

alternate - The alternate name of the resource.

selector - The selector.

element - The element from which the action has been unmarshalled. Used for namespace prefix resolution when performing XPath expressions.

parent - The action depending from.

Throws:

Method Detail

unmarshal

public static AbstractAction unmarshal(AbstractAction parent,
                                       Element element)
                                throws XMLException

XML unmarshaller for ResourceAction.

Parameters:

parent - The action depending from.

element - The XML element to unmarshall.

Returns:

The ResourceAction created.

Throws:

UnmarshalException - When the element and its content is not those expected.

XMLException

isMatching

public boolean isMatching(DataSet dataSet)
                   throws ExecutionException

Check if a key matches this action.

Specified by:

isMatching in interface CatalogEntry

Parameters:

dataSet - The set of datas used when the action is running.

Returns:

true if the key matches the identifier of this action, false otherwise.

Throws:

ExecutionException - If the candidate catalog key can't be checked.

feedContext

public void feedContext(DataSet dataSet,
                        Object alternate)
                 throws XPathException,
                        ExecutionException

Feeds the context with an alternate resource with no additional process, that is to say any Object should replace the candidate.

Specified by:

feedContext in interface CatalogEntry

Parameters:

dataSet - The set of datas used when the action is running.

alternate - The alternate resource that will feed the context as-is.

Throws:
