handleObject

public void handleObject(DmcUncheckedObject uco,
                         String infile,
                         int lineNumber)

                         DmcValueException,
                         DmcNameClashException

Description copied from interface: DmcUncheckedOIFHandlerIF

Process the object as required.

Specified by:

handleObject in interface DmcUncheckedOIFHandlerIF

Parameters:

uco - The object to be handled.

infile - Name of the file from which the object was loaded.

lineNumber - The line in the file where the object ended.

Throws:

ResultException - if problems occur

DmcValueException - if values are incorrect

DmcNameClashException - if names clash

findNamedDMO

public DmcObject findNamedDMO(DmcObjectName name)

Description copied from interface: DmcNameResolverIF

Finds a DMO based on its name.

Specified by:

findNamedDMO in interface DmcNameResolverIF

Parameters:

name - the name of the object

Returns:

A Dark Matter Object.

findNamedObject

public DmcNamedObjectIF findNamedObject(DmcObjectName name)

Description copied from interface: DmcNameResolverIF

Finds a named object based on its name.

Specified by:

findNamedObject in interface DmcNameResolverIF

Returns:

the named object.

findNamedObject

public DmcNamedObjectIF findNamedObject(DmcObjectName name,
                                        int attributeID)

Description copied from interface: DmcNameResolverIF

Finds a named object based on its name and indicates the attribute via which the reference is being made. This method is used via the DmcObject and is primarily intended to handle the situation where we must resolve internal type definitions as opposed to class definitions. This is due to the fact that we create internal type definitions for classes that have the same name as the associated classes.

Specified by:

findNamedObject in interface DmcNameResolverIF

Parameters:

name - the name of an object

attributeID - the attribute by which it is named

Returns:

the named object
