org.eclipse.jdt.core.dom
Class SwitchCase


java.lang.Object
  extended by 

org.eclipse.jdt.core.dom.ASTNode
      extended by 

org.eclipse.jdt.core.dom.Statement
          extended by 
org.eclipse.jdt.core.dom.SwitchCase

public class SwitchCase
extends Statement

Switch case AST node type. A switch case is a special kind of node used only in switch statements. It is a Statement in name only.

 SwitchCase:
                case Expression  :
                default :
 

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

Field Summary
static  ChildPropertyDescriptor EXPRESSION_PROPERTY
          The "expression" structural property of this node type.

          Returns a list of structural property descriptors for this node type.
 void setExpression ( Expression expression)
          Sets the expression of this switch case, or clears it (turns it into the "default:" case).

Field Detail

EXPRESSION_PROPERTY

public static final 
ChildPropertyDescriptor EXPRESSION_PROPERTY
The "expression" 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 case, or null if there is none (the "default:" case).

Returns:
the expression node, or null if there is none

setExpression

public void setExpression(
Expression expression)
Sets the expression of this switch case, or clears it (turns it into the "default:" case).

Parameters:
expression - the expression node, or null to turn it into the "default:" case
Throws:
IllegalArgumentException - if:
  • the node belongs to a different AST
  • the node already has a parent
  • a cycle in would be created

isDefault

public boolean isDefault()
Returns whether this switch case represents the "default:" case.

This convenience method is equivalent to getExpression() == null.

Returns:
true if this is the default switch case, and false if this is a non-default switch case
