getCondition

public IExpr getCondition()

This method returns the condition expression.

Returns:

the condition expression.

getThenNode

public ITslNode getThenNode()

this method returns the node that should be used if the condition evaluates to true.

Returns:

The node that should be used if the condition evaluates to true.

getElseNode

public ITslNode getElseNode()

this method returns the node that should be used if the condition evaluates to false.

Returns:

The node that should be used if the condition evaluates to false.

expand

public void expand(IValueSource source,
 OutputBuffer output,
 ILanguage language)

Description copied from interface: ITslNode

The expand method should evaluate the node for the given language, and append the result to the output buffer supplied. When the node also contains child elements, this expand method should invoke the child elements too.

Specified by:

expand in interface ITslNode

Parameters:

source - Object containing the values for the current domain.

output - The output buffer the result of this node should be appended to.

language - The language for which the node should be evaluated.

visit

public void visit(ITslNodeVisitor visitor)

Description copied from interface: ITslNode

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

Specified by:

visit in interface ITslNode

Parameters:

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

toString

public String toString()

Overrides:

toString in class Object
