Detailed Description

fixed-length blocked sequential output base class

Prerequisite

BlockIO

Definition at line 173 of file blockio.h.

Constructor & Destructor Documentation

◆ BlockOutput() [1/2]

casacore::BlockOutput::BlockOutput	(	const char *	,
		int	,
		int	= 1,
		FITSErrorHandler	errhandler = FITSError::defaultHandler )

Construction can be done either from a filename or from a file descriptor.

The remaining arguments are the the logical record size and number of records that make up a physical record followed by the output stream that is used to write error messages to.

References casacore::FITSError::defaultHandler().

◆ BlockOutput() [2/2]

casacore::BlockOutput::BlockOutput	(	int	,
		int	,
		int	= 1,
		FITSErrorHandler	errhandler = FITSError::defaultHandler )

References casacore::FITSError::defaultHandler().

◆ ~BlockOutput()
