Constructor Detail

Statement

public Statement(Tree tree,
                 int scope,
                 Node parent,
                 InstructionContainer instructionContainer,
                 List<InstructionHandle> instructions)

Creates a new Statement object.

Parameters:

tree - the control flow tree to which this node belongs

scope - the lexical scope of the node (0 = top-level scope)

parent - the node's parent (null if the node has no parent)

instructionContainer - a JODE object representing the statement

instructions - the list of instructions in the statement's method (the whole method, not just the statement)

Method Detail

getMethodInvocations

public List<MethodInvocation> getMethodInvocations()

Returns the methods that this statement invokes in the order in which they are invoked. If the same method is invoked more than once, it will appear in the list more than once.

Overrides:

getMethodInvocations in class Node

Returns:

a list of Java method handles, or an empty list if this statement does not invoke any methods

toString

public String toString()

Converts the statement to a string.

Overrides:

toString in class Object

Returns:

a source-code-like string representing the statement

getExpression

protected Expression getExpression()

Returns the statement's expression.

Returns:

a JODE object representing a Java expression, or null if the statement has no expression (e.g., return void statements)
