                                     DestinationAccessException

Serializes the given query, executes it, and the deserializes the response.

Parameters:

configContext - The ErpConfigContext of this call.

query - The Query to be executed.

querySerializer - The QuerySerializer to be used to write the query and read the response.

Returns:

The body of the response received by the given query.

Throws:

QuerySerializationException - If the query could not be serialized

QueryExecutionException - If any Exception occured during execution of the query.

DestinationNotFoundException - If the Destination cannot be found.

DestinationAccessException - If the destination is not of type DestinationType.HTTP or there is an issue while accessing destination information.

getRequestUri

@Nonnull
protected URI getRequestUri(@Nonnull
                                     ErpConfigContext configContext,

                               DestinationAccessException

Executes the given serializedQuery as a HttpUriRequest, returning the body of the HttpResponse received.

Parameters:

configContext - The ErpConfigContext of this call.

serializedQuery - The SerializedQuery to execute.

Returns:

The body of the response received by the given query.

Throws:

QuerySerializationException - If the query could not be serialized.

QueryExecutionException - If any Exception occured during execution of the query.

getRequestBodyWithHeader

@Nonnull
protected com.sap.cloud.sdk.s4hana.connectivity.HttpRequestExecutor.RequestBodyWithHeader getRequestBodyWithHeader(ErpConfigContext configContext,
                                                                                                                            @Nonnull

Returns a wrapper object which encapsulates the HTTP request body and headers. This method can be overridden to manipulate the request before submitting, e.g. signing queries, adding timestamps.

Parameters:

configContext - The ErpConfigContext of this call.

query - The Query to be executed.
