Interface VerificationPointDataProvider

All Known Implementing Classes:
DatabaseVPDataProvider

public interface VerificationPointDataProvider

An implementation of this class creates a Verification Point Data object based on the verification point metadata in the specialized Verification Point object.

A class implementing this interface is a pluggable link between a Verification Point class (which defines a verification point's metadata) and a Verification Point Data class (which encapsulates and serializes the data for a verification point).

When you implement a Verification Point Data class from this interface, you implement the captureData method for populating a Verification Point Data object for a given Verification Point object. The Verification Point Data Provider class knows about the structure of both the Verification Point Data class (which it is building) and the Verification Point class (which specifies the data to capture).

This is an important abstraction for general types of verification points (such as object data or object properties) where many different objects may provide access to the same type of data.

An implementation of this interface can be "plugged into" an existing verification point implementation to provide verification point data from a new verification point data source.

An implementation of this interface is used with static verification points (for building expected and actual data objects) and with dynamic verification points (for building actual data objects only).

The VerificationPointDataProvider interface is part of the verification point framework that you use to implement your own verification point classes. The verification point framework also includes:

Method Summary
 VerificationPointData captureData(java.lang.Object theObject, VerificationPoint theVP)
          This method builds an expected or actual data object of type VerificationPointData.
 

Method Detail

captureData

public VerificationPointData captureData(java.lang.Object theObject,
                                         VerificationPoint theVP)

This method builds an expected or actual data object of type VerificationPointData. The method builds the object according to the metadata in the VerificationPoint class.

Parameters:
theObject - The component-under-test.
theVP - The Verification Point object that contains the verification point's metadata.
