public class ComponentMapper

extends java.lang.Object

Service Class

This class enables a mapping of hierarchical component elements and the TextualInstantiation they are declared in to the TextualInstantiation they are instantiated with.
This mapping can be retrieved lateron, which is neccessary for the translation of global joins.

Field Summary

(package private) static boolean	debug Spam out debuggin information, if debug is true
private java.util.Hashtable	hashHierarchicalComponentsToHashtable Maps (basic) hierarchical components to another hashtable, that TextualInstantiation to TextualInstantiation, namely those that correspond to the instantiation of the component in this context.

Constructor Summary

ComponentMapper()
Default Constructor

Method Summary

void

enterTextualInstantiation(org.w3c.dom.Element component, TextualInstantiation tinst, TextualInstantiation subTinst) Create an entry in Component * TextualInstantiation ---> TextualInstantiation The first TextualInstantiation is the declaringContext, the result TextualInstantiation is the (sub-)declared one.

TextualInstantiation

retrieveTextualInstantiation(org.w3c.dom.Element component, TextualInstantiation tinst) Get the TextualInstantiation according to the mapping Component * TextualInstantiation ---> TextualInstantiation The first TextualInstantiation is the declaringContext, the result TextualInstantiation is the (sub-)declared one. If the TextualInstantiation is not entered yet, it is created with the empty constructor.

Method Detail

retrieveTextualInstantiation

public TextualInstantiation retrieveTextualInstantiation(org.w3c.dom.Element component,
                                                         TextualInstantiation tinst)
                                                  throws java.lang.Exception

Get the TextualInstantiation according to the mapping

Component * TextualInstantiation ---> TextualInstantiation

The first TextualInstantiation is the declaringContext, the result TextualInstantiation is the (sub-)declared one.

If the TextualInstantiation is not entered yet, it is created with the empty constructor.

enterTextualInstantiation

public void enterTextualInstantiation(org.w3c.dom.Element component,
                                      TextualInstantiation tinst,
                                      TextualInstantiation subTinst)
                               throws java.lang.Exception

Create an entry in
Component * TextualInstantiation ---> TextualInstantiation

The first TextualInstantiation is the declaringContext, the result TextualInstantiation is the (sub-)declared one.
