Member Function Documentation

Associate()

def scripts.multiemitter.MultiEmitter.Associate	(		self,
			key,
			emitter
	)

Associates a key with an emitter.

Definition at line 51 of file multiemitter.py.

    def Associate(self, key, emitter):
        """Associates a key with an emitter."""
        self._key_to_emitter[key] = emitter
 

FileEmitter()

def scripts.multiemitter.MultiEmitter.FileEmitter	(		self,
			filename,
			key = None
	)

Creates an emitter for writing to a file.

When this MultiEmitter is flushed, the contents of the emitter are written
to the file.

Arguments:
filename: a string, the path name of the file
key: provides an access key to retrieve the emitter.

Returns: the emitter.

Definition at line 33 of file multiemitter.py.

        return e
 

Find()

def scripts.multiemitter.MultiEmitter.Find	(		self,
			key
	)

Returns the emitter associated with |key|.

Definition at line 55 of file multiemitter.py.

Flush()

def scripts.multiemitter.MultiEmitter.Flush	(		self,
			writer = None
	)

Writes all pending files.

Arguments:
writer: a function called for each file and it's lines.

Definition at line 59 of file multiemitter.py.
