Constructor Detail

MappingLookupDatabase

public MappingLookupDatabase(LookupDatabase subDatabase,
                             java.util.Map mapping)

Method Detail

addIndex

public void addIndex(java.lang.String className,
                     LookupIndex index)

Creates an object set by adding a classname/index mapping.

Overrides:

addIndex in class LookupDatabase

addIndex

public void addIndex(java.lang.String className,
                     LookupIndex index,
                     java.util.Set lookupSet)

Creates an object set by adding a classname/index mapping, and supplies the set of objects for that mapping too.

Overrides:

addIndex in class LookupDatabase

addObject

public void addObject(java.lang.Object ob)

Adds an object to the database. It must fall into one of a previously- defined object set; i.e., you must have called addIndex() already with one of its ancestor classes.

Overrides:

addObject in class LookupDatabase

validObjectsFor

public java.util.Iterator validObjectsFor(java.lang.Class classy)

Returns valid object set for a registered class.

Overrides:

validObjectsFor in class LookupDatabase

validObjectsFor

public java.util.Iterator validObjectsFor(java.lang.String classname)

Returns valid object set for a registered class by class name.

Overrides:

validObjectsFor in class LookupDatabase

lookupObject

public java.lang.Object lookupObject(java.lang.Class classy,
                                     java.lang.Object parameter)
                              throws LookupFailedException

Looks up an object based on its class and a parameter. If the parameter is in the mapping, the mapped version is used instead; otherwise it's passed through unmolested.

Overrides:

lookupObject in class LookupDatabase

Throws:

LookupFailedException

keyOf

public java.lang.Object keyOf(java.lang.Object victim)

Returns the lookup key of an object. (does not currently do a reverse mapping)

Overrides:

keyOf in class LookupDatabase

contains

public boolean contains(java.lang.Object ob)

True if object is in the database, and can therefore be looked up.

Overrides:

contains in class LookupDatabase

referenceFor

public LookupReference referenceFor(java.lang.Object ob)

Returns a LookupReference for an object.

Overrides:

referenceFor in class LookupDatabase
