Detailed Description

A streambuf class for determining byte counts.

Definition at line 49 of file OCountStream.H.

Constructor & Destructor Documentation

countstreambuf()

countstreambuf ( std::streamsize  precount = 0 )

inline

Construct null, or with precount size.

Definition at line 84 of file OCountStream.H.

Member Function Documentation

overflow()

virtual int overflow ( int  c = EOF )

inlineprotectedvirtual

Handle output counting via overflow.

Definition at line 59 of file OCountStream.H.

References Foam::constant::universal::c.

seekpos()

virtual std::streampos seekpos ( std::streampos  , std::ios_base::openmode  which = std::ios_base::in|std::ios_base::out  )

inlineprotectedvirtual

Set position pointer to absolute position.

For the counter, any positioning is ignored and it always acts like seekpos(0), which resets the count.

Returns

The number of bytes counted
