Java Tutorial » Log » Log   30. 1. 7. The MemoryHandler is a circular buffer in memory. The MemoryHandler is intended for use as a quick way to store messages. The messages have to be sent to another handler to write them to an external source. Because the buffer is circular, older log records eventually are overwritten by newer records. The properties on the MemoryHandler are listed in the following table. Property Name Description Default Value MemoryHandler.level Log level for the handler Level.INFO MemoryHandler.filter Filter to use undefined MemoryHandler.size Size of the circular buffer (in bytes) 1,000 MemoryHandler.push Defines the push level ?he minimum level that will cause messages to be sent to the target handler Level.SEVERE MemoryHandler.target Specifies the name of the target Handler class (undefined) 30. 1. Log 30. 1. 1.  A full list of levels. 30. 1. 2.  The StreamHandler serves chiefly as a base class for all handlers that write log messages to some OutputStream. 30. 1. 3.  The ConsoleHandler writes log messages to System.err. 30. 1. 4.  The SocketHandler writes log messages to the network over a specified TCP port. 30. 1. 5.  The FileHandler is able to write to a single file, or write to a rotating set of files as each file reaches a specified maximum size. 30. 1. 6.  The FileHandler class supports filename patterns. 30. 1. 7.  The MemoryHandler is a circular buffer in memory. 30. 1. 8.  The ErrorManager 30. 1. 9.  Information Logging 30. 1. 10.  Log to a file 30. 1. 11.  Guaranteeing proper class and method names
