Method Detail

clone

@Contract("null -> null; !null -> !null")
public static <T> T clone(T orig)

cloneCloneable

public static <T extends Cloneable> T cloneCloneable(T cloneable)

cloneCollectionMembers

@Contract("!null -> !null; null -> null")
public static <T> List<T> cloneCollectionMembers(Collection<T> collection)

Returns:

List that can be freely used.

cloneMembersToCollection

public static <T> void cloneMembersToCollection(Collection<T> target,
                                                Collection<T> source)

cloneCollectionMembersWithoutIds

@Experimental
@Contract("!null -> !null; null -> null")
public static <T> List<T> cloneCollectionMembersWithoutIds(Collection<T> collection)

Returns:

List that contains its members clones. For members that are Containerable the IDs are cleared. FIXME: BEWARE - UNFINISHED - does not clear IDs if members are PCVs; does it only for Containerables - should be named maybe "copyForReuse" and use complexClone with the strategy of REUSE for all prism data See Containerable.cloneWithoutId() and its TODOs.

cloneIfImmutable

@Contract("null -> null; !null -> !null")
@Nullable
public static <C extends Containerable> C cloneIfImmutable(@Nullable
                                                           C value)

toImmutable

@Contract("null -> null; !null -> !null")
public static <CF extends Cloneable & Freezable> CF toImmutable(@Nullable
                                                                CF input)

Provides an immutable version of the input: - If the input is immutable, returns it as is. - If the input is mutable, creates an immutable clone.

toImmutableContainerable

@Contract("null -> null; !null -> !null")
public static <C extends Containerable> C toImmutableContainerable(@Nullable
                                                                   C input)

Provides an immutable version of the input: - If the input is immutable, returns it as is. - If the input is mutable, creates an immutable clone. This method is needed (in addition to toImmutable(Cloneable)) because Containerable is not Freezable.
