Method Details
-
propertyDescriptors
Returns a list of structural property descriptors for this node type. Clients must not modify the result.- Parameters:
apiLevel- the API level; one of theAST.JLS*constants- Returns:
- a list of property descriptors (element type:
StructuralPropertyDescriptor) - Since:
- 3.38
-
propertyDescriptors
Returns a list of structural property descriptors for this node type. Clients must not modify the result.- Parameters:
apiLevel- the API level; one of theAST.JLS*constantspreviewEnabled- the previewEnabled flag- Returns:
- a list of property descriptors (element type:
StructuralPropertyDescriptor) - Since:
- 3.38
-
getExpression
Returns the conditional expression of this pattern, ornullif there is none (the "default:" case).- Returns:
- the expression node, or
nullif there is none - Since:
- 3.38
-
getPattern
Returns the pattern of this Guarded Pattern, oremptyif there is none.- Returns:
- the pattern node
(element type:
Pattern) - Throws:
UnsupportedOperationException- if this operation is used other than JLS18UnsupportedOperationException- if this expression is used with previewEnabled flag as false- Restriction:
- This method is not intended to be referenced by clients as it is a part of Java preview feature.
-
setExpression
Sets the conditional expression of this pattern, or clears it (turns it into the "default:" case).- Parameters:
expression- the expression node, ornullto 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
- Since:
- 3.38
-
setPattern
Sets the pattern of this switch case.- Throws:
UnsupportedOperationException- if this operation is used not for JLS18UnsupportedOperationException- if this operation is used without previewEnabled- Since:
- 3.38
-
setRestrictedIdentifierStartPosition
protected void setRestrictedIdentifierStartPosition(int restrictedIdentifierStartPosition) A character index into the original restricted identifier source string, or-1if no restricted identifier source position information is available for this node;-1by default.- Restriction:
- since 3.30
-
getRestrictedIdentifierStartPosition
public int getRestrictedIdentifierStartPosition()A character index into the original restricted identifier source string, or-1if no restricted identifier source position information is available for this node;-1by default.- Since:
