Method Detail

batchElements

public static <T> java.util.List<java.util.List<T>> batchElements(@Nonnull
                                                                  java.util.List<T> elements,
                                                                  int batchSize)

Given a list of elements and a batchSize, this method distributes the elements into batches with the batchSize. Each batch is represented by a List of elements and all the batches are grouped and represented by a List<List> of elements, which is returned by the method.

Type Parameters:

T - the type of the draft elements.

Parameters:

elements - the list of elements to split into batches.

batchSize - the size of each batch.

Returns:

a list of lists where each list represents a batch of elements.

getReferenceWithKeyReplaced

@Nullable
public static <T> io.sphere.sdk.models.Reference<T> getReferenceWithKeyReplaced(@Nullable
                                                                                          io.sphere.sdk.models.Reference<T> reference,
                                                                                          @Nonnull
                                                                                          java.util.function.Supplier<io.sphere.sdk.models.Reference<T>> keyInReferenceSupplier)

Given a reference to a resource of type T, this method checks if the reference is expanded. If it is, then it executes the keyInReferenceSupplier and returns it's result. Otherwise, it returns the supplied reference as is. Since, the reference could be null, this method could also return null if the reference was not expanded.

This method expects the passed supplier to either

Type Parameters:

T - the type of the resource.

Parameters:

reference - the reference of the resource to check if it's expanded.

keyInReferenceSupplier - the supplier to execute and return its result if the reference was expanded.

Returns:

returns the result of the keyInReferenceSupplier if the reference was expanded. Otherwise, it returns the supplied reference as is.

getResourceIdentifierWithKey

@Nullable
public static <T extends io.sphere.sdk.models.WithKey> io.sphere.sdk.models.ResourceIdentifier<T> getResourceIdentifierWithKey(@Nullable
                                                                                                                                         io.sphere.sdk.models.Reference<T> reference)

Given a reference to a resource of type T, this method checks if the reference is expanded. If it is, then it return the resource identifier with key. Otherwise, it returns the resource identifier with id. Since, the reference could be null, this method could also return null if the reference was not expanded.

Type Parameters:

T - the type of the resource.

Parameters:

reference - the reference of the resource to check if it's expanded.

Returns:

returns the resource identifier with key if the reference was expanded. Otherwise, it returns the resource identifier with id.

isUuid

public static boolean isUuid(@Nonnull
                             java.lang.String id)

Given an id as String, this method checks whether if it is in UUID format or not.

Parameters:

id - to check if it is in UUID format.

Returns:

true if it is in UUID format, otherwise false.
