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 :

 Switch case allows multiple expressions and '->' as part of Java 12 preview feature (JEP 325)
                case [ Expression { , Expression } ]  { : | ->}
                default { : | ->}

Field Details

EXPRESSION_PROPERTY

public static final ChildPropertyDescriptor EXPRESSION_PROPERTY

Deprecated.

In the JLS 12 15.28.1 API, this property is replaced by EXPRESSIONS2_PROPERTY.

The "expression" structural property of this node type (child type: Expression).

Since:

3.0

EXPRESSIONS2_PROPERTY

public static final ChildListPropertyDescriptor EXPRESSIONS2_PROPERTY

The "expression" structural property of this node type (child type: Expression). (added in JEP 325).

Since:

3.18

SWITCH_LABELED_RULE_PROPERTY

public static final SimplePropertyDescriptor SWITCH_LABELED_RULE_PROPERTY

The "switchLabeledRule" structural property of this node type (type: Boolean).

Since:

3.18

Method Details

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()

Deprecated.

use expressions() (see JLS 12)

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

expressions

public List expressions()

Returns the list of expressions of this switch case, or empty if there is none (the "default:" case).

Returns:

the list of expression nodes (element type: Expression)

Throws:

UnsupportedOperationException - if this operation is used below JLS14

Since:

3.22

setExpression

public void setExpression(Expression expression)

Deprecated.

see JLS 12

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

setSwitchLabeledRule

public void setSwitchLabeledRule(boolean switchLabeledRule)

Sets the switchLabeledRule of this switch case as true or false. true indicates "->" and false indicates ":".

Parameters:

switchLabeledRule - true or false

Throws:

UnsupportedOperationException - if this operation is used below JLS14

Since:

3.22

isSwitchLabeledRule

public boolean isSwitchLabeledRule()

Gets the switchLabeledRule of this switch case as true or false. true indicates "->" and false indicates ":".

Returns:

switchLabeledRule true or false

Throws:

UnsupportedOperationException - if this operation is used below JLS14

Since:

3.22

isDefault

public boolean isDefault()

Returns whether this switch case represents the "default:" case.

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

Returns:

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