ActiveOutFile

Name

ActiveOutFile -- An object that actively updates its file stream when updated.

Description

This is the file I/O equivalent of ActiveGraph: it takes an OutFile object, a target (datafeed) object, and a selector, which it uses to extract data from the object and send it to the file.

Protocols adopted by ActiveOutFile

MessageProbe CREATABLE

Methods

Phase: Creating

- setDataFeed: d
The setDataFeed: method sets the object that will be probed for data.
- setHDF5Dataset: (id <HDF5>)hdf5Dataset
Sets an extensible HDF5 dataset that data will be appended.
- setFileObject: aFileObj
The setFileObject: method sets the file object to which the data will be sent.

Phase: Using

- (double)getCurrentValue
Returns the last probed value
- (void)step
The step method fires the probe, reads the value from the object, and sends the value to the file.
