All Implemented Interfaces:

Comparable<AstNode>, Iterable<Node>

public class LabeledStatement
extends AstNode

A labeled statement. A statement can have more than one label. In this AST representation, all labels for a statement are collapsed into the "labels" list of a single LabeledStatement node.

Node type is Token.EXPR_VOID.

Method Detail

getLabels

public List<Label> getLabels()

Returns label list

setLabels

public void setLabels(List<Label> labels)

Sets label list, setting the parent of each label in the list. Replaces any existing labels.

Throws:

IllegalArgumentException - } if labels is null

addLabel

public void addLabel(Label label)

Adds a label and sets its parent to this node.

Throws:

IllegalArgumentException - } if label is null

getStatement

public AstNode getStatement()

Returns the labeled statement

getLabelByName

public Label getLabelByName(String name)

Returns label with specified name from the label list for this labeled statement. Returns null if there is no label with that name in the list.

setStatement

public void setStatement(AstNode statement)

Sets the labeled statement, and sets its parent to this node.

Throws:

IllegalArgumentException - if statement is null

getFirstLabel

public Label getFirstLabel()

hasSideEffects

public boolean hasSideEffects()

Overrides:

hasSideEffects in class AstNode

toSource

public String toSource(int depth)

Description copied from class: AstNode

Emits source code for this node. Callee is responsible for calling this function recursively on children, incrementing indent as appropriate.

Note: if the parser was in error-recovery mode, some AST nodes may have null children that are expected to be non-null when no errors are present. In this situation, the behavior of the toSource method is undefined: toSource implementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse.

Specified by:

toSource in class AstNode

Parameters:

depth - the current recursion depth, typically beginning at 0 when called on the root node.

visit

public void visit(NodeVisitor v)

Visits this node, then each label in the label-list, and finally the statement.

Specified by:

visit in class AstNode

Parameters:

v - the object to call with this node and its children
