Method Detail

getNodeType

public int getNodeType()

Description copied from class: ASTNode

Returns an integer value identifying the type of this concrete AST node. The values are small positive integers, suitable for use in switch statements.

For each concrete node type there is a unique node type constant (name and value). The unique node type constant for a concrete node type such as CastExpression is ASTNode.CAST_EXPRESSION.

Specified by:

getNodeType in class ASTNode

Returns:

one of the node type constants

subtreeMatch

public boolean subtreeMatch(ASTMatcher matcher,
                            Object other)

Description copied from class: ASTNode

Returns whether the subtree rooted at the given node matches the given other object as decided by the given matcher.

Specified by:

subtreeMatch in class ASTNode

Parameters:

matcher - the matcher

other - the other object, or null

Returns:

true if the subtree matches, or false if they do not match

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
