Field Details

PATTERN_PROPERTY

public static final ChildPropertyDescriptor PATTERN_PROPERTY

The "pattern" structural property of this node type (child type: Pattern). (added in JEP 406).

EXPRESSION_PROPERTY

public static final ChildPropertyDescriptor EXPRESSION_PROPERTY

The "expression" structural property of this node type (child type: Expression). (added in JEP 406).

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)

propertyDescriptors

public static List propertyDescriptors(int apiLevel,
 boolean previewEnabled)

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

previewEnabled - the previewEnabled flag

Returns:

a list of property descriptors (element type: StructuralPropertyDescriptor)

getExpression

public Expression getExpression()

Returns the conditional expression of this pattern, or null if there is none (the "default:" case).

Returns:

the expression node, or null if there is none

getPattern

public Pattern getPattern()

Returns the pattern of this Guarded Pattern, or empty if there is none.

Returns:

the pattern node (element type: Pattern)

Throws:

UnsupportedOperationException - if this operation is used other than JLS18

UnsupportedOperationException - if this expression is used with previewEnabled flag as false

setExpression

public void setExpression(Expression expression)

Sets the conditional expression of this pattern, 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

setPattern

public void setPattern(Pattern pattern)

Sets the pattern of this switch case.

Throws:

UnsupportedOperationException - if this operation is used not for JLS18

UnsupportedOperationException - if this operation is used without previewEnabled

setRestrictedIdentifierStartPosition

protected void setRestrictedIdentifierStartPosition(int restrictedIdentifierStartPosition)

A character index into the original restricted identifier source string, or -1 if no restricted identifier source position information is available for this node; -1 by default.

getRestrictedIdentifierStartPosition

public int getRestrictedIdentifierStartPosition()

A character index into the original restricted identifier source string, or -1 if no restricted identifier source position information is available for this node; -1 by default.
