Example 1 with LogModuleVersion

use of com.google.apphosting.api.logservice.LogServicePb.LogModuleVersion in project appengine-java-standard by GoogleCloudPlatform.

the class LocalLogService method read.

/**
 * Reads log records from the in-memory log list and applies user-specified filters to the results
 * to return.
 *
 * @param request A set of parameters that indicate restrictions on the results that should be
 *     returned.
 * @return A set of logs matching the parameters given. If the number of logs returned exceed
 *     either the user-specified amount or the API-specified limit, then an offset is returned
 *     that has a reference to the next record to read from in subsequent requests.
