Constructor Detail

Condition

public Condition(Position position,
                 Operator opr,
                 ISemanticNode left,
                 ISemanticNode right)

Constructs the condition node with the required arguments.

Parameters:

position - The position information for the node.

opr - The condition operator.

left - The left-hand-side of the condition expression.

right - The right-hand-side of the condition expression.

Method Detail

getOperator

public Operator getOperator()

This method returns the operator of this expression.

Returns:

the operator of this expression.

getLeftExpression

public ISemanticNode getLeftExpression()

This method returns the left hand side expression of the operator.

Returns:

the left hand side expression of the operator.

getRightExpression

public ISemanticNode getRightExpression()

This method returns the right hand side expression of the operator.

Returns:

the right hand side expression of the operator.

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:

toString in class SemanticNodeBase
