Constructor.

Method Detail

addSymbol

public boolean addSymbol(java.lang.String symbolName,
                         int type)

Add a new symbol to the hashtable. The name of the symbol is the key. there is NO definition yet.

Parameters:

symbolName - Hashtable key.

Returns:

true if successful; false otherwise.

addParent

public boolean addParent(java.lang.String symbolName,
                         java.util.Vector parentNames,
                         java.util.Vector parentROIDs)

Insert a SINGLE new definition to a symbol with symbolName. If the symbol is not declared in the hashtable yet this function will do the task also.

Parameters:

symbolName - Hashtable key.

Returns:

true if successful; false otherwise.

addParent

public boolean addParent(java.lang.String symbolName,
                         parentListElement element)

Insert a SINGLE new definition to a symbol with symbolName. If the symbol is not declared in the hashtable yet this function will do the task also.

Parameters:

symbolName - Hashtable key.

element - new definition to be added.

Returns:

true if successful; false otherwise.

modifyParent

public boolean modifyParent(java.lang.String symbolName,
                            int ID,
                            java.util.Vector parentNames,
                            java.util.Vector parentROIDs)

modify the parent with ID (from zero in linked list) to the new content.

Parameters:

symbolName - name of the symbol.

ID - ID of the element in the linked list, starts from zero.

parentNames - the new parent names.

parentROIDs - the new parent ROIDs.

Returns:

true if successful; false otherwise.

addMuEx

public boolean addMuEx(java.lang.String symbolName,
                       java.util.Vector parentROIDs,
                       java.util.Vector parentNames)

Add Mutually Exclusive roids to the symbol with symbolName.

Parameters:

symbolName - the spec. symbol in interest.

parentROIDs - MuEx condition roids.

parentNames - MuEx condition names.

Returns:

true when successful; false otherwise.

getParents

public java.util.LinkedList getParents(java.lang.String symbolName)

Deprecated. Return the linked list of parents of the specified symbol.

Parameters:

symbolName - name of the symbol.

Returns:

the symbol table linked list.

getParentNames

Parameters:

ID - the index of the parent in the list.

Returns:

a Vector of parent names.

getParentRoids
