applyWarningCallback

public void applyWarningCallback(@Nonnull
                                 java.lang.String warningMessage)

Given a warningMessage string, this method calls the warningCallback function which is set to this instance of the BaseSyncOptions. If there warningCallback is null, this method does nothing.

Parameters:

warningMessage - the warning message to supply to the warningCallback function.

applyErrorCallback

public void applyErrorCallback(@Nonnull
                               java.lang.String errorMessage,
                               @Nullable
                               java.lang.Throwable exception)

Given an errorMessage and an exception, this method calls the errorCallback function which is set to this instance of the BaseSyncOptions. If there errorCallback is null, this method does nothing.

Parameters:

errorMessage - the error message to supply as first param to the errorCallback function.

exception - optional Throwable instance to supply to the errorCallback function as a second param.

applyErrorCallback

public void applyErrorCallback(@Nonnull
                               java.lang.String errorMessage)

Parameters:

errorMessage - the error message to supply as first param to the errorCallback function.

applyErrorCallback(String, Throwable)

getBatchSize

public int getBatchSize()

Gets the batch size used in the sync process. During the sync there is a need for fetching existing resources so that they can be compared with the new resource drafts. That's why the input is sliced into batches and then processed. It allows to reduce the query size for fetching all resources processed in one batch. E.g. value of 30 means that 30 entries from input list would be accumulated and one API call will be performed for fetching entries responding to them. Then comparision and sync are performed.

This batch size is set to 30 by default.

Returns:

option that indicates capacity of batch of resources to process.

getBeforeUpdateCallback

@Nullable
public TriFunction<java.util.List<io.sphere.sdk.commands.UpdateAction<U>>,V,U,java.util.List<io.sphere.sdk.commands.UpdateAction<U>>> getBeforeUpdateCallback()

Returns the beforeUpdateCallback TriFunction<List<UpdateAction< U>>, V, U, List<UpdateAction<U>>> function set to this BaseSyncOptions. It represents a callback function which is applied (if set) on the generated list of update actions to produce a resultant list after the filter function has been applied.

Returns:

the beforeUpdateCallback TriFunction<List<UpdateAction< U>>, V, U, List<UpdateAction<U>>> function set to this BaseSyncOptions.

getBeforeCreateCallback

@Nullable
public java.util.function.Function<V,V> getBeforeCreateCallback()

Returns the beforeCreateCallback Function<V, Optional<V>> function set to this BaseSyncOptions. It represents a callback function which is applied (if set) on the resource draft of type V before it is created to produce a resultant draft after the filter function has been applied.

Returns:

the beforeUpdateCallback Function<V, Optional<V>> function set to this BaseSyncOptions.

Given a List of UpdateAction, a new resource draft of type V and the old existing resource of the type U, this method applies the beforeUpdateCallback function which is set to this instance of the BaseSyncOptions and returns the result. If the beforeUpdateCallback is null or updateActions is empty, this method does nothing to the supplied list of updateActions and returns the same list. If the result of the callback is null, an empty list is returned.

Parameters:

updateActions - the list of update actions to apply the beforeUpdateCallback function on.

newResourceDraft - the new resource draft that is being compared to the old resource.

oldResource - the old resource that is being compared to the new draft.

Returns:

a list of update actions after applying the beforeUpdateCallback function on. If the beforeUpdateCallback function is null or updateActions is empty, the supplied list of updateActions is returned as is. If the return of the callback is null, an empty list is returned.

applyBeforeCreateCallBack

@Nonnull
public java.util.Optional<V> applyBeforeCreateCallBack(@Nonnull
                                                                V newResourceDraft)

Given a new resource draft of type V this method applies the beforeCreateCallback function which is set to this instance of the BaseSyncOptions and returns the result.

• If the beforeCreateCallback is null, this method does nothing to the supplied resource draft and returns it as is, wrapped in an optional.
• If the return of beforeCreateCallback is null, an empty optional is returned.
• Otherwise, the result of the beforeCreateCallback is returned in the optional.

Parameters:

newResourceDraft - the new resource draft that should be created.

Returns:

an optional containing the resultant resource draft after applying the beforeCreateCallback function on. If the beforeCreateCallback function is null, the supplied resource draft is returned as is, wrapped in an optional.
