Interface ValueBuilder

All Known Implementing Classes:

DefaultValueBuilder

public interface ValueBuilder

Classes that implement the ValueBuilder interface evaluate an arbitrary expression to produce a string value. The string value is then assigned as the value to a SIF element or attribute.

The ValueBuilder interface is used by the SIFDTD, SIFDataObject, and Mappings classes when evaluating XPath-like query strings. It enables developers to customize the way the ADK evaluates value expressions in these query strings to produce a value for a SIF element or attribute. The DefaultValueBuilder implementation supports $(variable) token replacement as well as @com.class.method style calls to static Java methods.
