Method Detail

batchDrafts

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

Given a list of resource (e.g. categories, products, etc..) drafts and a batchSize, this method separates the drafts into batches with the batchSize. Each batch is represented by a List of resources and all the batches are grouped and represented by an List<List> of resources, which is returned by the method.

Type Parameters:

T - the type of the draft resources.

Parameters:

drafts - the list of drafts to split into batches.

batchSize - the size of each batch.

Returns:

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

replaceCustomTypeIdWithKeys

@Nullable
public static <T extends io.sphere.sdk.types.Custom> io.sphere.sdk.types.CustomFieldsDraft replaceCustomTypeIdWithKeys(@Nonnull
                                                                                                                                 T resource)

Given a resource of type T that extends Custom (i.e. it has CustomFields, this method checks if the custom fields are existing (not null) and they are reference expanded. If they are then it returns a CustomFieldsDraft instance with the custom type key in place of the id of the reference. Otherwise, if its not reference expanded it returns a CustomFieldsDraft with the id not replaced. If the resource has no or null Custom, then it returns null.

Type Parameters:

T - the type of the resource.

Parameters:

resource - the resource to replace its custom type id, if possible.

Returns:

an instance of CustomFieldsDraft instance with the custom type key in place of the id, if the custom type reference was existing and reference expanded on the resource. Otherwise, if its not reference expanded it returns a CustomFieldsDraft with the id not replaced with key. If the resource has no or null Custom, then it returns null.

replaceReferenceIdWithKey

@Nullable
public static <T> io.sphere.sdk.models.Reference<T> replaceReferenceIdWithKey(@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.

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.
