Constructor Detail

TernaryExpressionNode

public TernaryExpressionNode(ConditionalExpressionTree tree,
                             Node condition,
                             Node thenOperand,
                             Node elseOperand,
                             LocalVariableNode ternaryExpressionVar)

Creates a new TernaryExpressionNode.

Parameters:

tree - the ConditionalExpressionTree for the node

condition - node representing the condition checked by the expression

thenOperand - node representing the "then" case of the expression

elseOperand - node representing the "else" case of the expression

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

Method Detail

getConditionOperand

public Node getConditionOperand()

Gets the node representing the conditional operand for this node

Returns:

the condition operand node

getThenOperand

public Node getThenOperand()

Gets the node representing the "then" operand for this node

Returns:

the "then" operand node

getElseOperand

public Node getElseOperand()

Gets the node representing the "else" operand for this node

Returns:

the "else" operand node

getTernaryExpressionVar

public LocalVariableNode getTernaryExpressionVar()

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

Returns:

the variable for this ternary expression

getTree

public ConditionalExpressionTree 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

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

toString

hashCode in class Object

getOperands

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
