ChildPropertyDescriptor OPERAND_PROPERTY

The "operand" 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

getOperator

public 
PrefixExpression.Operator getOperator()

Returns the operator of this prefix expression.

Returns:: the operator

setOperator

public void setOperator(
PrefixExpression.Operator operator)

Sets the operator of this prefix expression.

Parameters:: operator - the operator
Throws:: IllegalArgumentException - if the argument is incorrect

getOperand

public 
Expression getOperand()

Returns the operand of this prefix expression.

Returns:: the operand expression node

setOperand

public void setOperand(
Expression expression)

Sets the operand of this prefix expression.

Parameters:

expression - the operand expression node

Throws:


IllegalArgumentException

- if:

the node belongs to a different AST
the node already has a parent
a cycle in would be created
