getMTGNodeCount

public long getMTGNodeCount()

Number of nodes generated.

Returns:

long Number of nodes generated.

getMTGRootNode

protected MTGNode getMTGRootNode()

Allows MTGTranslator to obtain the root node of the graph generated from translating MTG data file.

Returns:

processTokens

public boolean processTokens(java.lang.String[] tokens)
                      throws MTGError.MTGGraphBuildException

Processes tokens and generates nodes and edges as necessary to the current graph.

Parameters:

tokens - Array of strings representing tokens.

Throws:

MTGError.MTGGraphBuildException

removeInterScaleTopoRelations

public void removeInterScaleTopoRelations()
                                   throws MTGError.MTGPlantFrameException

Removes inter-scale topological relations (i.e. successor and branching edges).

Throws:

MTGError.MTGPlantFrameException

removeTypes

public void removeTypes()

Creates Node classes or Modules Types and stores them in the root node.

storeNodeListInRoot

public void storeNodeListInRoot()

Put node list into root node after building graph.
