Detailed Description

A stream for writing binary transducers.

An example:

#include "HfstOutputStream.h"

      ...

      // Write three HFST transducers in binary format to file named "testfile"
      HfstOutputStream out("testfile", FOMA_TYPE);
      out << foma_transducer1 
          << foma_transducer2 
          << foma_transducer3;
      out.close();

For more information on HFST transducer structure, see this page.

Constructor & Destructor Documentation

HfstOutputStream	(	ImplementationType	type,
		bool	hfst_format = true
	)

Create a stream to standard output for writing binary transducers of type type. hfst_format defines whether transducers are written in hfst format or as such in their backend format.

HfstOutputStream	(	const std::string &	filename,
		ImplementationType	type,
		bool	hfst_format = true
	)

Open a stream to file filename for writing binary transducers of type type. hfst_format defines whether transducers are written in hfst format or as such in their backend format.

If the file exists, it is overwritten.

~HfstOutputStream

(

void

)

Destructor.

Member Function Documentation

void close

(

void

)

Close the stream.

If the stream points to standard output, nothing is done.

HfstOutputStream & operator<<

(

HfstTransducer &

transducer

)

Write the transducer transducer in binary format to the stream.

All transducers must have the same type as the stream, else a TransducerTypeMismatchException is thrown.

Exceptions

TransducerTypeMismatchException

HfstOutputStream & redirect

(

HfstTransducer &

transducer

)

An alias for operator<<.
