org.eclipse.jdt.core.dom.Statement
          
org.eclipse.jdt.core.dom.SwitchStatement

public class SwitchStatement
extends Statement
extends Statement

Switch statement AST node type.

 SwitchStatement:
                switch ( Expression )
                        { { SwitchCase | Statement } } }
 SwitchCase:
                case Expression  :
                default :

SwitchCase nodes are treated as a kind of Statement.

Since:: 2.0
Restriction:: This class is not intended to be instantiated by clients.

Field Detail

EXPRESSION_PROPERTY

public static final 
ChildPropertyDescriptor EXPRESSION_PROPERTY

The "expression" structural property of this node type.

Since:: 3.0

STATEMENTS_PROPERTY

public static final 
ChildListPropertyDescriptor STATEMENTS_PROPERTY

The "statements" structural property of this node type.

Since:: 3.0

Method Detail

propertyDescriptors

public static 
List propertyDescriptors(int apiLevel)

Returns a list of structural property descriptors for this node type. Clients must not modify the result.

Parameters:: apiLevel - the API level; one of the AST.JLS* constants
Returns:: a list of property descriptors (element type: StructuralPropertyDescriptor)
Since:: 3.0

getExpression

public 
Expression getExpression()

Returns the expression of this switch statement.

Returns:: the expression node

setExpression

public void setExpression(
Expression expression)

Sets the expression of this switch statement.

Parameters:

expression - the new expression node

Throws:


IllegalArgumentException

- if:

the node belongs to a different AST
the node already has a parent
a cycle in would be created

statements

public 
List statements()

Returns the live ordered list of statements for this switch statement. Within this list, SwitchCase nodes mark the start of the switch groups.

Returns:: the live list of statement nodes (element type: Statement)
