                  MemoryHandler

A handler class which buffers logging records in memory, periodically flushing them to a target handler. Flushing occurs whenever the buffer is full, or when an event of a certain severity or greater is seen.

Instance Methods

[hide private]

__init__(self, capacity, flushLevel=40, target=None)
Initialize the handler with the buffer size, the level at which flushing should occur and an optional target.

source code

shouldFlush(self, record)
Check for buffer full or a record at the flushLevel or higher.

source code

setTarget(self, target)
Set the target handler for this handler.

source code

flush(self)
For a MemoryHandler, flushing means just sending the buffered records to the target, if there is one.

source code

close(self)
Flush, set the target to None and lose the buffer.

Method Details

[hide private]

init(self, capacity, flushLevel=40, target=None)
(Constructor)

source code

Initialize the handler with the buffer size, the level at which flushing should occur and an optional target.

Note that without a target being set either here or via setTarget(), a MemoryHandler is no use to anyone!

Overrides: Filterer.__init__

shouldFlush(self, record)

source code

Check for buffer full or a record at the flushLevel or higher.

Overrides: BufferingHandler.shouldFlush

flush(self)

source code

For a MemoryHandler, flushing means just sending the buffered records to the target, if there is one. Override if you want different behaviour.

Overrides: Handler.flush

close(self)

source code

Flush, set the target to None and lose the buffer.

Overrides: Handler.close
