Constructor Details

ExpressionList

public ExpressionList(Position position,
 ISemanticNode... expressions)

Constructs the node with the required arguments.

Parameters:

position - Position information for the node.

expressions - Array containing the value expressions of the list.

Method Details

getExpressions

public ISemanticNode[] getExpressions()

This method returns an array containing the expressions of the list's values.

Returns:

an array containing the expressions of the list's values.

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.

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.

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:
