Methods Summary
public java.lang.ObjectgetDescriptor()

return
the descriptor instance to associate with this XMLNode

public voidsetElementValue(com.sun.enterprise.deployment.node.XMLElement element, java.lang.String value)
receives notiification of the value for a particular tag

param
element the xml element
param
value it's associated value

public voidstartElement(com.sun.enterprise.deployment.node.XMLElement element, org.xml.sax.Attributes attributes)
SAX Parser API implementation, we don't really care for now.

public org.w3c.dom.NodewriteDescriptor(org.w3c.dom.Node parent, java.lang.String nodeName, com.sun.enterprise.deployment.MethodPermissionDescriptor descriptor, com.sun.enterprise.deployment.EjbDescriptor ejb)
write the descriptor class to a DOM tree and return it

param
parent node in the DOM tree
param
node name for the root element of this xml fragment
param
the descriptor to write
return
the DOM tree top node

Write the descriptor in a DOM tree which root element is provided

param
subNode the root element for the DOM fragment
param
descriptor the method permisison descriptor
param
ejb the ejb descriptor the above method permission belongs to
