Constructor Details

InstanceOfNode

public InstanceOfNode(InstanceOfTree tree,
 Node operand,
 TypeMirror refType,
 Types types)

Create an InstanceOfNode.

Parameters:

tree - instanceof tree

operand - the expression in the instanceof tree

refType - the type in the instanceof

types - types util

InstanceOfNode

public InstanceOfNode(InstanceOfTree tree,
 Node operand,
 @Nullable Node patternNode,
 TypeMirror refType,
 Types types)

Create an InstanceOfNode.

Parameters:

tree - instanceof tree

operand - the expression in the instanceof tree

patternNode - the pattern node or null if there is none

refType - the type in the instanceof

types - types util

Method Details

getOperand

public Node getOperand()

getBindingVariable

@Deprecated
public @Nullable LocalVariableNode getBindingVariable()

Deprecated.

Use getPatternNode() or getBindingVariables() instead.

Returns the binding variable for this instanceof, or null if one does not exist.

Returns:

the binding variable for this instanceof, or null if one does not exist

getBindingVariables
