Method Details

getConcreteClassTypeArguments

public List<Type> getConcreteClassTypeArguments()

Description copied from class: JaversType

For generic types, returns a list of actual Class arguments. For example, for Set<String>, returns String. Non-concrete (like ?) or missing type arguments like are defaulted to Object.

For array, returns List with Class.getComponentType()

Overrides:

getConcreteClassTypeArguments in class JaversType

spawnConstructorArgs

protected Object[] spawnConstructorArgs(Type baseJavaType)

Overrides:

spawnConstructorArgs in class JaversType

spawnConstructorArgTypes

protected Class[] spawnConstructorArgTypes()

Overrides:

spawnConstructorArgTypes in class JaversType

getTypeMapperLazy

protected TypeMapperLazy getTypeMapperLazy()

map

public abstract Object map(Object sourceEnumerable,
 EnumerableFunction mapFunction,
 OwnerContext owner)

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

Returns:

immutable Enumerable

getEnumerableInterface

public abstract Class<?> getEnumerableInterface()

map

public Object map(Object sourceEnumerable,
 Function mapFunction)

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

mapPreservingSourceItemType

public Object mapPreservingSourceItemType(Object sourceEnumerable,
 Function mapFunction)

For building Shadows. Item type of new enumerable matters only for arrays

map

public abstract Object map(Object sourceEnumerable,
 Function mapFunction,
 boolean filterNulls)

isEmpty

public abstract boolean isEmpty(Object container)

empty

public abstract Object empty()

filterToList

public <T> List<T> filterToList(Object source,
 Class<T> filter)

Returns a new, unmodifiable Enumerable with filtered items, nulls are omitted.

items

protected abstract Stream<Object> items(Object source)

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()
