method adds the token to root
Parameters:
  tokens -



buildTree
public void buildTree(String dslFile)(Code)
the method will take the dsl file and build a DSLTree using the Node class.
Parameters:
  dslFile -



buildTree
public void buildTree(Reader dslcontents)(Code)
the method uses the DSLAdapter to get the contents of the DSL mapping file.
Parameters:
  dslcontents -



buildTree

getConditionChildren
public Node[] getConditionChildren(String text)(Code)
the method will tokenize the text and try to find the node that matches and return the children. the method will traverse down the network as far as it can and return the children at that level.
Parameters:
  text -



getConditionChildrenList
public ArrayList getConditionChildrenList(String text, boolean addChildren)(Code)
for convienance, the method will return a list of strings that are children of the last node found. If the editor wants to generate the children strings, call the method with true
Parameters:
  text -



getConsequenceChildren
public Node[] getConsequenceChildren(String text)(Code)
the method will tokenize the text and try to find the node that matches and return the children. the method will traverse down the network as far as it can and return the children at that level.
Parameters:
  text -



getConsequenceChildrenList
public ArrayList getConsequenceChildrenList(String text, boolean addChildren)(Code)
