Looks for a charger comment in either the first or second token. Returns first one found.

Parameters:

token1 -

token2 -

Returns:

extractChargerComment

public static String extractChargerComment(Token t1,
                                           Token t2)

parseChargerLayout

public void parseChargerLayout(String chargerComment,
                               GraphObject go)

makeConcept

public Concept makeConcept(Graph g,
                           String type,
                           Referent referent,
                           String layout)

Processes the concept from cgif07.jj (as converted into CGIFParser.java)

Parameters:

graph - The graph into which the concept will be inserted

type - The type name to be made into a type label

referent - the referent as established by the parser

layout - CGX layout string, if present in a CGIF comment

makeTypeLabel

public void makeTypeLabel(Graph g,
                          String type,
                          String layout)
                   throws CGIFSubtypeException

Use the CGIF information to instantiate a new type label.

Parameters:

graph - The graph into which the concept will be inserted

type - The type name to be made into a type label

layout - CGX layout string, if present in a CGIF comment

Throws:

CGIFSubtypeException

makeGenSpecLink

public void makeGenSpecLink(Graph g,
                            String subtype,
                            String supertype,
                            String layout)
                     throws CGIFSubtypeException

Processes the gen spec link from cgif07.jj (as converted into CGIFParser.java)

Parameters:

g -

subtype -

supertype -

layout - CGX layout string, if present in a CGIF comment

Throws:

CGIFSubtypeException

makeRelation

public Relation makeRelation(Graph g,
                             String name,

                             String layout)
                      throws CGIFVariableException

Processes the relation from cgif07.jj (as converted into CGIFParser.java)

Parameters:

g - the graph in which this actor is to be inserted

name - name of the actor

variables - zero or more variables, to be associated with concepts. Last one is considered output arc's target.

layout - CGX layout string, if present in a CGIF comment

Returns:

Throws:

CGIFVariableException
