Detailed Description

Abstract superclass for any class that reads a format that produces Regions from a file.

Intended use:

Public interface

Synopsis

Provide a well defined set of operations for reading region files, regardless of the data format.

Note that some file formats allow for plotting options to be defined as well as the regions. These options are read and stored in a record of..., the contents of this record is ill-defined (ie. there is no standard).

There may come a time where a standard is necessary.

virtual casacore::RFReader::~RFReader ( )

inlinevirtual

Destructor.

Member Function Documentation

virtual Record* casacore::RFReader::options ( )

inlinevirtual

Provides access to the plotting options that were found in the region file.

Definition at line 233 of file RFReaderWriter.h.

References casacore::RFReaderWriter::options_p.

virtual bool casacore::RFReader::read ( Record &  region )

pure virtual

reported, false otherwise.

If false is returned, the details can be found using lastError(). Any valid Regions that were read from the file are placed in the given vector (which is cleared first).

Implemented in casacore::AipsIOReaderWriter.

Referenced by readFile().

virtual bool casacore::RFReader::readFile ( const String &  file, Record &  region  )

inlinevirtual

Calls setFile() then read().

Definition at line 244 of file RFReaderWriter.h.
