Constructor Details

Not

public Not(ISemanticTreeBuilder semantics,
 Position position,
 ISemanticNode node)

Constructs the node with the required arguments.

Parameters:

semantics - Semantic builder that may be used to request type information.

position - Position information for the node.

node - The node that should be inverted.

Method Details

getExpression

public ISemanticNode getExpression()

This method returns the expression node that should be inverted.

Returns:

the expression node that should be inverted.

collectScopedObjects

public void collectScopedObjects(ScopedObjects resultSet)

Description copied from interface: ISemanticNode

This method may be used to collect the names of the objects that need to be in scope in order to evaluate the expression of this node. The object passed to the method will be enriched with the names of the objects that need to be in scope.

Parameters:

resultSet - The object that should be used to add the names of the objects that need to be in scope to.

getChildNodes

public ISemanticNode[] getChildNodes()

Description copied from interface: ISemanticNode

This method returns an array containing the child nodes. The order of the child nodes in the array is not defined, and the array may be empty for nodes that do not have child nodes.

Returns:

Array containing the child nodes of this node.

visit

public void visit(ISemanticNodeVisitor visitor)

Description copied from interface: ISemanticNode

This method allows a type safe visitation of the node. The visit method will not invoke the visitor for any child nodes.

Parameters:

visitor - The visitor that should be invoked for this node.

toString

public String toString()

Overrides:

toString in class SemanticNodeBase
