Method Details

map

public Object map(Object sourceOptional_,
 EnumerableFunction mapFunction,
 OwnerContext owner)

Description copied from class: EnumerableType

OwnerContext aware version of EnumerableType.map(Object, EnumerableFunction, OwnerContext)

Overrides:

map in class CollectionType

Returns:

immutable List

map

public Object map(Object sourceOptional_,
 Function mapFunction)

Description copied from class: EnumerableType

Returns a new Enumerable (unmodifiable when possible) with items from sourceEnumerable mapped by mapFunction.

Overrides:

map in class EnumerableType

items

protected Stream<Object> items(Object source)

Overrides:

items in class CollectionType

isEmpty

public boolean isEmpty(Object optional)

Overrides:

isEmpty in class CollectionType

empty

public Object empty()

Overrides:

empty in class CollectionType

getEnumerableInterface

public Class<?> getEnumerableInterface()

Overrides:

getEnumerableInterface in class CollectionType

canBePrototype

public boolean canBePrototype()

Specified by:

canBePrototype in class JaversType

isInstance

public boolean isInstance(Object cdo)

Specified by:

isInstance in class JaversType

getRawDehydratedType

protected Type getRawDehydratedType()

Type for JSON representation. For Values it's simply baseJavaType. For ManagedTypes (references to Entities and ValueObjects) it's GlobalId because JaVers serializes references in the 'dehydrated' form.

getBaseJavaClass

public Class getBaseJavaClass()
