public class WideningConversionNode
extends Node

A node for the widening primitive conversion operation. See JLS 5.1.2 for the definition of widening primitive conversion.

A WideningConversionNode does not correspond to any tree node in the parsed AST. It is introduced when a value of some primitive type appears in a context that requires a different primitive with more bits of precision.

P> R accept(NodeVisitor<R,P> visitor,
 P p)

Description copied from class: Node

Accept method of the visitor pattern.

Specified by:

accept in class Node

Type Parameters:

R - result type of the operation

P - parameter type

Parameters:

visitor - the visitor to be applied to this node

p - the parameter for this operation

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(@Nullable Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

getOperands

@SideEffectFree
public Collection<Node> getOperands()

Description copied from class: Node

Returns a collection containing all of the operand Nodes of this Node.

Specified by:

getOperands in class Node

Returns:

a collection containing all of the operand Nodes of this Node
