Detailed Description

A Blob buffer for Aips++ ByteIO.

This class makes it possible to use the AIPS++ AipsIO class on top of a Blob buffer. In this way it is possible to write an AIPS++ LSQFit object directly into a Blob buffer. Note that it is even possible to mix AipsIO and Blob puts; the same is true for gets. Of course, the order of reading must be the same as the order of writing.

Member Function Documentation

isReadable()

virtual bool dp3::blob::BlobAipsIO::isReadable ( ) const

virtual

Is the Blob stream readable?

isSeekable()

virtual bool dp3::blob::BlobAipsIO::isSeekable ( ) const

virtual

Is the Blob stream seekable?

isWritable()

virtual bool dp3::blob::BlobAipsIO::isWritable ( ) const

virtual

Is the Blob stream writable?

length()

virtual casacore::Int64 dp3::blob::BlobAipsIO::length ( )

virtual

Get the length of the Blob stream. Returns 0 if the stream is not seekable.

read() [1/2]

virtual casacore::Int64 dp3::blob::BlobAipsIO::read ( casacore::Int64  size, void *  buf, bool  throwException  )

virtual

Read size bytes from the Blob stream. Returns the number of bytes actually read.

Exceptions

AipsError

if the requested number of bytes could not be read, unless throwException is set to False.

read() [2/2]

virtual casacore::Int dp3::blob::BlobAipsIO::read ( casacore::uInt  size, void *  buf, bool  throwException  )

virtual

write() [1/2]

virtual void dp3::blob::BlobAipsIO::write ( casacore::Int64  size, const void *  buf  )

virtual

Write the number of bytes to the Blob stream.

Exceptions

An	exception if the stream is not writable. The 2nd write and read function are defined for the read/write signatures in older casacore versions (pre v2.0).

write() [2/2]

virtual void dp3::blob::BlobAipsIO::write ( casacore::uInt  size, const void *  buf  )

virtual
