          ua.gradsoft.termware.DoubleTerm

All Implemented Interfaces:

Serializable, Cloneable

public final class DoubleTerm
extends AbstractPrimitiveTerm

Term, which represend floating point value with java 'double' semantics.

Method Summary

boolean	eq(Term t) are term logically equal to x
double	getDouble() get double value, if this term represent double, otherwise throw UnsupportedOperationException Note, that this method does not provide conversion of other numeric types to double.
String	getName() name of term
Number	getNumber() return number, which holded in this term.
int	getPrimaryType0() return code of level-0 primary type
boolean	isDouble() is this term represets Double ?
boolean	isNumber() is this term represents Number ?
void	print(PrintWriter out) print term to out
Term	termClone() since double is immutable - return this.
int	termCompare(Term t) compare functions.
