Interface IJavaPredicate_LEGACY

All Superinterfaces:

IJavaElement, IJavaExpression, IJavaOperation

@Ser
public interface IJavaPredicate_LEGACY
extends IJavaOperation

Java AST interface to represent a Java predicate. A predicate is a boolean expression that evaluates to true or false.

Note: Currently, logical expressions using non short-circuiting operators OR (|), AND (&), or XOR(^) are not allowed.

Method Summary

Modifier and Type	Method	Description
IJavaPredicate_LEGACY	duplicate()	Duplicate this element.
boolean	isLitteralFalse()	Determine if the predicate represents the simple literal value 'false' ( null IDENT 'false').
boolean	isLitteralTrue()	Determine if the predicate represents the simple literal value 'true' ( null IDENT 'true').
void	reverse()	Reverse the predicate.
boolean	simplify()	Recursively simplify predicates like: "x == true", "x != true", "x == false", "x != false" to things like "x" or "!x"

Method Details

isLitteralTrue

boolean isLitteralTrue()

Determine if the predicate represents the simple literal value 'true' ( null IDENT 'true').

Returns:

true if the predicate represents the literal true

isLitteralFalse

boolean isLitteralFalse()

Determine if the predicate represents the simple literal value 'false' ( null IDENT 'false').

Returns:

true if the predicate represents the literal false

reverse

void reverse()

Reverse the predicate. Example: "x == 3" becomes "x != 3".

simplify

boolean simplify()

Recursively simplify predicates like: "x == true", "x != true", "x == false", "x != false" to things like "x" or "!x"

Returns:

true if at least one simplification was performed

duplicate

IJavaPredicate_LEGACY duplicate()

Description copied from interface: IJavaElement

Duplicate this element.

Specified by:

duplicate in interface IJavaElement

Specified by:

duplicate in interface IJavaExpression

Specified by:

duplicate in interface IJavaOperation

Returns:

a (possibly) duplicated object of the same type
