FluentHelperUpdate(String servicePath)
Instantiates this fluent helper using the given service path to send the requests.
|
Modifier and Type | Method and Description |
---|---|
com.sap.cloud.sdk.odatav2.connectivity.ODataUpdateResult |
execute(ErpConfigContext configContext)
Executes the underlying update request.
|
protected abstract EntityT |
getEntity()
The entity object to be updated by calling the
execute(ErpConfigContext) method. |
protected Class<? extends EntityT> |
getEntityClass()
Returns a class object of the type this fluent helper works with.
|
protected com.sap.cloud.sdk.odatav2.connectivity.ODataUpdateRequestBuilder |
getQueryBuilder()
Creates an instance of the
ODataUpdateRequestBuilder based on the Entity class. |
FluentHelperT |
ignoreVersionIdentifier()
The update request will ignore the given version identifier and writes the contained changes, regardless of any
changes on the remote entity.
|
FluentHelperT |
ignoringVersionIdentifier(boolean ignore)
You can specify whether the given version identifier shall be ignored and, as a consequence, the changes to the
remote entity shall be written in any case regardless of any previous changes on the remote entity.
|
FluentHelperT |
includingFields(EntityField<EntityT,?>... fields)
Allows to explicitly specify entity fields that shall be sent in an update request regardless if the values of
these fields have been changed.
|
com.sap.cloud.sdk.odatav2.connectivity.ODataUpdateRequest |
toQuery()
Provides access to the underlying Query object, to allow for custom integration scenarios not yet supported by
the virtual data model.

FluentHelperT |
withErrorHandler(com.sap.cloud.sdk.odatav2.connectivity.ErrorResultHandler<?> errorResultHandler)
An error handling class that implements the
ErrorResultHandler interface can be
attached to this fluent helper. |

ErrorResultHandler
interface can be
attached to this fluent helper. This allows custom logic to be called when an error occurs in the execute
method. If this method is not called, then an instance of ODataVdmErrorResultHandler
is used. Only one handler can be attached at a time per fluent helper object, so
calling this multiple times will replace the handler.errorResultHandler
