Interface TypeMap<H>

All Superinterfaces:

ByTypeSupplier<H,RuntimeException>

All Known Implementing Classes:

CachingTypeMapWrapper, GraphTypeMap

@ParametersAreNonnullByDefault
public interface TypeMap<H>
extends ByTypeSupplier<H,RuntimeException>

Type to Object map. association is not 1 - 1. if we have type1 -> object that if type2 is subtype of type1, also type2 -> object this is useful for resolving: ITC_INHERITANCE_TYPE_CHECKING

Method Summary

Modifier and Type	Method and Description
default H	get(Type t) get the object associated to a compatible type, only if there is only one.
Set<H>	getAll(Type t) Get all Objects associated to all unrelated compatible types.
H	getExact(Type t) Get the the Object associated to type.
boolean	putIfNotPresent(Type type, H object) Associate object to type if no existing association present.
boolean	remove(Type type) remove type association.
default TypeMap<H>	safePut(Type type, H object) Associate object with type.

Method Detail

getAll

@Nonnull
Set<H> getAll(Type t)

Get all Objects associated to all unrelated compatible types. for example we habe Object O of type T a subtype of T1 and T2. if this typemap contains Objects mapped to T1 and T2, those 2 objects will be returned if T1 and T2 are not related (subtypes of each other) if T1 extends T2 the obeject mapped to the most specific type is returned.

Parameters:

t -

Returns:

get

@Nullable
default H get(Type t)

get the object associated to a compatible type, only if there is only one.

Specified by:

get in interface ByTypeSupplier<H,RuntimeException>

Parameters:

t -

Returns:

getExact

@Nullable
H getExact(Type t)

Get the the Object associated to type.

Parameters:

t -

Returns:

putIfNotPresent

@CheckReturnValue
boolean putIfNotPresent(Type type,
                                          H object)

Associate object to type if no existing association present.

Parameters:

type -

object -

Returns:

safePut

default TypeMap<H> safePut(Type type,
                           H object)

Associate object with type. if there is an existing association a exception will be thrown.

Parameters:

type -

object -

remove

@CheckReturnValue
boolean remove(Type type)

remove type association.

Parameters:

type -

Returns:
