Interface DescriptorBuilder

All Known Implementing Classes:

DescriptorBuilderImpl

public interface DescriptorBuilder

This is an object that uses the Builder pattern in order to generate a Descriptor (for binding) or a Filter (for searching). It is intended to facilitate query strings of method calls that is simple to understand and read.
