Method Detail

c2c

protected abstract Map c2c()

TODO identity versus null mappings

Returns:

a map from IObject classes ModelBased classes.

map

public ModelBased map(Filterable source)

map

public Collection map(Collection source)

map

public Map map(Map source)

filter

public Filterable filter(String fieldId,
                Filterable source)

Specified by:

filter in interface Filter

Overrides:

filter in class ContextFilter

filter

public Collection filter(String fieldId,
                Collection source)

Description copied from class: ContextFilter

iterates over the contents of the collection and filters each. Adds itself to the context. This is somewhat dangerous.

Specified by:

filter in interface Filter

Overrides:

filter in class ContextFilter

filter

public Map filter(String fieldId,
         Map source)

Description copied from class: ContextFilter

filters both the key and value sets of the map. Adds itself to the context. Somewhat dangerous.

Specified by:

filter in interface Filter

Overrides:

filter in class ContextFilter

findClass

protected Class findClass(Class source)

findKeyTarget

public Object findKeyTarget(Object current)

extension point which subclasses can override to better map the keys of maps.

findCollectionTarget

public Object findCollectionTarget(Object current)

extension point which subclasses can override to better map the values of collections and maps.

findTarget

public Object findTarget(Object current)

known immutables are return unchanged.

Parameters:

current -

Returns:

a possibly uninitialized object which will be finalized as the object graph is walked.
