Constructor Details

SwitchExpressionNode

public SwitchExpressionNode(TypeMirror type,
 Tree switchExpressionTree,
 LocalVariableNode switchExpressionVar)

Creates a new SwitchExpressionNode.

Parameters:

type - the type of the node

switchExpressionTree - the SwitchExpressionTree for this node

switchExpressionVar - a variable created by dataflow to which each result expression of the switch expression is assigned. Its value should be used for the value of the switch expression

Method Details

getTree

public Tree getTree()

Description copied from class: Node

Returns the Tree in the abstract syntax tree, or null if no corresponding tree exists. For instance, this is the case for an ImplicitThisNode.

Specified by:

getTree in class Node

Returns:

the corresponding Tree or null

getSwitchExpressionVar

public LocalVariableNode getSwitchExpressionVar()

This is a variable created by dataflow to which each result expression of the switch expression is assigned. Its value should be used for the value of the switch expression.

Returns:

the variable for this switch expression

accept

public <R,
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

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

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
