                       double value)

Method Detail

equals

public boolean equals(Object that)

Overrides:

equals in class Object

getKind

public NodeKind getKind()

Specified by:

getKind in class JsNode

getValue

public double getValue()

hashCode

public int hashCode()

Overrides:

hashCode in class Object

isBooleanFalse

public boolean isBooleanFalse()

isBooleanTrue

public boolean isBooleanTrue()

isDefinitelyNull

public boolean isDefinitelyNull()

Description copied from class: JsExpression

True if the target expression is definitely null.

Specified by:

isDefinitelyNull in class JsExpression

traverse

public void traverse(JsVisitor v,
                     JsContext ctx)

Description copied from interface: JsVisitable

Causes this object to have the visitor visit itself and its children.

Parameters:

v - the visitor that should traverse this node

ctx - the context of an existing traversal

isInternable

public boolean isInternable()

Description copied from class: JsLiteral

Return true if the literal can be interned. A literal can be interned if it is constant, has value semantics and its construction does not involve evaluation of any construct other than internable literals.

Overrides:

isInternable in class JsLiteral
