Detailed Description

Convenient class used to save a set of features in a file. In the RAW format, the dimension of the features is not saved. Each data of each feature is saved as a double float value (8 bytes). In the SPRO formats, the flags comes from the configuration. A raw file can be read using a FeatureFileReaderRaw object.

		const Config &	c
	)		`[explicit]`

Member Function Documentation

void W::close ( ) [virtual]

Closes the writer. A automatic call to close() is done when the writer is destroyed. But, if the file must be re-opened without destroying the writer, you MUST close the writer previously.

Exceptions:

IOException if an I/O error occurs

Reimplemented from alize::FileWriter.
