Method Detail

getInstance

public static AdapterFactory getInstance()

Initialise everything and get a new factory instance. This is an expensive operation and triggers Dozer to initialise itself, therefore this should only be called once and the factory re-used (e.g. as a singleton) to create all adapter instances.

Returns:

The factory instance

getInstance

public static AdapterFactory getInstance(java.util.List mappingFiles)

Initialise everything and get a new factory instance. This is an expensive operation and triggers Dozer to initialise itself, therefore this should only be called once and the factory re-used (e.g. as a singleton) to create all adapter instances. This version of the method takes a List of filenames, containing custom Dozer mapping definitions.

Parameters:

mappingFiles - A List of Dozer mapping filenames to use, or null if none

Returns:

The factory instance

createAdapter

public java.lang.Object createAdapter(java.lang.Class sourceInterface,
                                      java.lang.Object target,
                                      java.util.Map methodMappings)
                               throws AdapterCreationException

Creates a new adapter instance, which maps calls to it's methods to the appropriate method on the target object.

Parameters:

sourceInterface - The fully qualified interface type name that the adapter will implement

target - The target object to map calls to

methodMappings - A Map of target method names, keyed by source method name.

Returns:

A Proxy instance that maps calls.
