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.

Expression	getExpression() Returns the expression of this switch case, or null if there is none (the "default:" case).
boolean	isDefault() Returns whether this switch case represents the "default:" case.
static List	propertyDescriptors(int apiLevel) 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 (child type: Expression).

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
