Constructor Details

AssertionErrorNode

public AssertionErrorNode(Tree tree,
 Node condition,
 @Nullable Node detail,
 TypeMirror type)

Creates an AssertionErrorNode.

Parameters:

tree - tree for the assert statement or assert method

condition - the node of the condition when if false the assertion exception is thrown

detail - node for the expression after : in the assert statement, or null

type - the type of the exception thrown

Method Details

getCondition

@Pure
public Node getCondition()

The node of the condition that if it is false, the assertion exception is thrown.

Returns:

the node of the condition that if it is false, the assertion exception is thrown

getDetail

@Pure
public @Nullable Node getDetail()

The node for the expression after : in the assert statement, or null.

Returns:

node for the expression after : in the assert statement, or null

getTree

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()

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
