Member Function Documentation

void Vector::BLF::CompressedFile::close () [virtual]

Close file.

bool Vector::BLF::CompressedFile::eof () const [override], [virtual]

Check whether eofbit is set.

Returns

true if eofbit is set

Implements Vector::BLF::AbstractFile.

std::streamsize Vector::BLF::CompressedFile::gcount () const [override], [virtual]

Get characters returned by last read operation.

Returns

Number of characters

Implements Vector::BLF::AbstractFile.

bool Vector::BLF::CompressedFile::good () const [override], [virtual]

Check whether state of stream is good.

Returns

true if no error flags are set

Implements Vector::BLF::AbstractFile.

bool Vector::BLF::CompressedFile::is_open () const [virtual]

is file open?

Returns

true if file is open

void Vector::BLF::CompressedFile::open (const char * filename, std::ios_base::openmode openMode) [virtual]

open file

Parameters

filename file name
openMode open in read or write mode

void Vector::BLF::CompressedFile::read (char * s, std::streamsize n) [override], [virtual]

Read block of data.

This operation blocks until the data is available.

Parameters

s Pointer to data
n Requested size of data

Implements Vector::BLF::AbstractFile.

void Vector::BLF::CompressedFile::seekg (std::streamoff off, const std::ios_base::seekdir way = std::ios_base::cur) [override], [virtual]

Set position in input sequence.

Parameters

off Offset
way Direction

Implements Vector::BLF::AbstractFile.

void Vector::BLF::CompressedFile::seekp (std::streampos pos) [virtual]

Set position in output sequence.

Parameters

pos Position

std::streampos Vector::BLF::CompressedFile::tellg () [override], [virtual]

Get position in input sequence.

Returns

Read position

Implements Vector::BLF::AbstractFile.

std::streampos Vector::BLF::CompressedFile::tellp () [override], [virtual]

Get position in output sequence.

Returns

Write position

Implements Vector::BLF::AbstractFile.

void Vector::BLF::CompressedFile::write (const char * s, std::streamsize n) [override], [virtual]

Write block of data.

Parameters

s Pointer to data
n Size of data

Implements Vector::BLF::AbstractFile.
