Example
The following example uses get_web_source_operation
as part of a Plug-In "fetch" procedure in order to get meta data about the REST Data Source operation.
apex_plugin_util.get_web_source_operation (
p_plugin in apex_plugin.t_plugin,
p_web_source in apex_plugin.t_web_source,
p_params in apex_plugin.t_web_source_fetch_params,
p_result in out nocopy apex_plugin.t_web_source_fetch_result )
IS
l_web_source_operation apex_plugin.t_web_source_operation;
BEGIN
l_web_source_operation := apex_plugin_util.get_web_source_operation(
p_web_source => p_web_source,
p_db_operation => apex_plugin.c_db_operation_fetch_rows,
p_perform_init => true );
p_result.responses.extend( 1 );
apex_plugin_util.make_rest_request(
p_web_source_operation => l_web_source_operation,
--
p_response => p_result.responses( 1 ),
p_response_parameters => p_result.out_parameters );
END plugin_fetch;
