public class MethodInvocationNode
extends Node

A node for method invocation.

   target(arg1, arg2, ...)
 

CFGs may contain MethodInvocationNodes that correspond to no AST Tree, in which case, the tree field will be null.

Field Summary

Fields

Modifier and Type	Field	Description
protected final List<Node>	arguments	The arguments of the method invocation.
protected @Nullable ExpressionTree	iterableExpression	If this MethodInvocationNode is a node for an Iterator.next() desugared from an enhanced for loop, then the iterExpression field is the expression in the for loop, e.g., iter in for(Object o: iter.
protected final MethodAccessNode	target	The MethodAccessNode for the method being invoked.
protected final @Nullable MethodInvocationTree	tree	The tree for the method invocation.
protected final TreePath	treePath	The tree path to the method invocation.

Field Details

tree

protected final @Nullable MethodInvocationTree tree

The tree for the method invocation.

target

protected final MethodAccessNode target

The MethodAccessNode for the method being invoked. Includes the receiver if any. For a static method, the receiver may be a class name.

arguments

protected final List<Node> arguments

The arguments of the method invocation.

treePath

protected final TreePath treePath

The tree path to the method invocation.

iterableExpression

protected @Nullable ExpressionTree iterableExpression

If this MethodInvocationNode is a node for an Iterator.next() desugared from an enhanced for loop, then the iterExpression field is the expression in the for loop, e.g., iter in for(Object o: iter.

Is set by setIterableExpression(com.sun.source.tree.ExpressionTree).

Constructor Details

MethodInvocationNode

public MethodInvocationNode(@Nullable MethodInvocationTree tree,
 MethodAccessNode target,
 List<Node> arguments,
 TreePath treePath)

Create a MethodInvocationNode.

Parameters:

tree - for the method invocation

target - the MethodAccessNode for the method being invoked

arguments - arguments of the method invocation

treePath - path to the method invocation

MethodInvocationNode

public MethodInvocationNode(MethodAccessNode target,
 List<Node> arguments,
 TreePath treePath)

Method Details

getTarget

public MethodAccessNode getTarget()

getArguments

public List<Node> getArguments()

getArgument

public Node getArgument(int i)

getTreePath

public TreePath getTreePath()

getIterableExpression

public @Nullable ExpressionTree getIterableExpression()

If this MethodInvocationNode is a node for an Iterator.next() desugared from an enhanced for loop, then return the expression in the for loop, e.g., iter in for(Object o: iter. Otherwise, return null.

Returns:

the iter expression, or null if this is not a Iterator.next() from an enhanced for loop

setIterableExpression
