- All Implemented Interfaces:
- java.lang.Cloneable, Expression, ParseTree, VariableInitializer
- public class CastExpression
- extends NonLeaf
- implements Expression
The CastExpression
class represents
a cast expression of parse tree.
If the operator in the expression of the right operand has week unity,
this automatically produces the code in which the right operand
is enclosed by parenthesises.
In the case the caster is int
and
the right operand to be casted is p + q
,
this produces the code :
(int) (p + q)
