Constructor Summary

Variable()
default constructor

Variable(java.lang.String _name)
constructor containing a variable name

Variable(java.lang.String _name, OperandToken _data)
constructor containing the variables name and data

Method Summary

OperandToken	assign(OperandToken _data) Assign a new value to the variable
boolean	equals(java.lang.Object _data) implement the equals operator to find a variable with the correct name if _data is an instance of Variable then it compares the name of _data to the variable otherwise it calls the superclasses version
OperandToken	getData() Returns the variables data
java.lang.String	getName() Returns the variables name
boolean	isGlobal()
void	setGlobal(boolean globalB)
java.lang.String	toString() Converts the variable into a string.
java.lang.String	toString(java.lang.String[] operands) Converts the variable to a string.
