Field Details

OPERATOR_PROPERTY

public static final SimplePropertyDescriptor OPERATOR_PROPERTY

The "operator" structural property of this node type (type: PrefixExpression.Operator).

Since:

3.0

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

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
