Constructor Detail

UnaryOperatorNodeBase

public UnaryOperatorNodeBase(IASToken operatorToken,
                     ExpressionNodeBase operandNode)

Constructor.

Parameters:

operatorToken - The token representing the unary operator.

operandNode - The expresson node representing the operand.

UnaryOperatorNodeBase

protected UnaryOperatorNodeBase(UnaryOperatorNodeBase other)

Copy constructor.

Parameters:

other - The node to copy.

Method Detail

createPrefix

public static UnaryOperatorNodeBase createPrefix(IASToken operatorToken,
                                 ExpressionNodeBase operand)

Factory method for various kinds of unary prefix operator nodes.

createPostfix

public static UnaryOperatorNodeBase createPostfix(IASToken operatorToken,
                                  ExpressionNodeBase operand)

Factory method for various kinds of unary prefix operator nodes.

getChildCount

public int getChildCount()

Description copied from interface: IASNode

Get the number of children

Specified by:

getChildCount in interface IASNode

Overrides:

getChildCount in class NodeBase

Returns:

the number of children

getChild

public IASNode getChild(int i)

Description copied from interface: IASNode

Get a particular child of this node

Specified by:

getChild in interface IASNode

Overrides:

getChild in class NodeBase

Parameters:

i - the child's index

Returns:

the specified child

setChildren

protected void setChildren(boolean fillInOffsets)

Description copied from class: NodeBase

If this node has custom children (names, arguments, etc), shove them into the list of children. Used during parsing.

Overrides:

setChildren in class NodeBase

fillInOffsets

protected void fillInOffsets()

Description copied from class: NodeBase

If the start and end offsets haven't been set explicitly, fill them in based on the offsets of the children. Used during parsing. If the end offset is less than any of the kids' offsets, change fLocation.fEnd to encompass kids.

Overrides:

fillInOffsets in class NodeBase

resolveType

public ITypeDefinition resolveType(ICompilerProject project)

Description copied from interface: IExpressionNode

The type of the result of this expression. This method returns the IDefinition representing the type that is the result of this expression. This can differ from the IDefinition you get from resolve(), such as when called on a FunctionCallNode: resolve() will return the IDefinition for the Function, whereas resolveType() will return the return type of the Function.

Specified by:

resolveType in interface IExpressionNode

Overrides:

resolveType in class ExpressionNodeBase

Parameters:

project - The ICompilerProject to use to do lookups.

Returns:

The ITypeDefinition of the type this expression results in.

isDynamicExpression

public boolean isDynamicExpression(ICompilerProject project)

Description copied from interface: IExpressionNode

Does this expression evaluate to a dynamic value

Specified by:

isDynamicExpression in interface IExpressionNode

Overrides:

isDynamicExpression in class ExpressionNodeBase

Parameters:

project - The ICompilerProject to use to do lookups.

Returns:

true if we evaluate to something dynamic

getExpressionType

public IOperatorNode.ExpressionType getExpressionType()

Description copied from interface: IOperatorNode

Returns the type of expression that is represented by this node

Specified by:

getExpressionType in interface IOperatorNode

Returns:

the type of our expression

getOperandNode

public IExpressionNode getOperandNode()

Description copied from interface: IUnaryOperatorNode

Get expression acted on by the unary operator

Specified by:

getOperandNode in interface IUnaryOperatorNode

Returns:

the IExpressionNode

setExpression

public void setExpression(ExpressionNodeBase operandNode)

resolveIncrementOrDecrementType

protected ITypeDefinition resolveIncrementOrDecrementType(ICompilerProject project)

Utility method called by resolveType(ICompilerProject) in subclasses for the ++ and -- operators.
