Detailed Description

VisBufferImpls encapsulate one chunk of visibility data for processing.

Intended use:

Public interface

Prerequisite

Etymology

VisBufferImpl is a buffer for visibility data

Synopsis

This class contains 'one iteration' of the VisibilityIterator2 It is a modifiable buffer of values to which calibration and averaging can be applied. This allows processing of the data in larger blocks, avoiding some overheads for processing per visibility point or spectrum.

See MeasurementEquations for more details on how the VisBufferImpl is to be used.

When the user intends to allow asynchronous I/O they will need to use the VisBufferImplAsync and VisBufferImplAsyncWrapper classes; these are publicly derived from VisBufferImpl. Normally, the user should not explicitly use these classes but should use the helper class VisBufferImplAutoPtr which will ensure that the appropriate class is used.

To Do

reconcile vis/visCube usage: visCube, flagCube and weightMatrix are currently only correct when this VisBufferImpl got them from a VisIter, operations like -=, freqAverage() are only done for visibility() and flag().

feed1_pa() and feed2_pa() return an array of parallactic angles (each corresponds to the first receptor of the feed) one for each row in the current buffer. In contrast, feed_pa() calculates the angles for each antenna. These methods are implemented for VisBufferImpl only to benefit from caching of the feed and antenna IDs.

Note that feed_pa is a function instead of a cached value

Update coordinate info - useful for copied VisBufferImpls that need to retain some state for later reference. Presently this fills antenna, array, field and spectralWindow ids, time, frequency and number of rows. if dirDependent is set to false the expensive direction dependent calculation of parallactic or direction of antenna from pointing table is avoided Add more as needed.

return nCatOK_p ? nCat_p : fillnCat(); virtual void setNCat (const casacore::Int &))) { } virtual casacore::Int nCat() const { return This->nCat(); }Because of it being publicly exposed ...using nRow, nChannel, nCorr etc to determine the size of the buffer can be totally WRONG They MAY NOT represent the shape of a buffer filled in this iteration. Decide what is the right value (depending on where the vb is coming from) for you for the size of the buffer. i.e (nCorr(), nChannel(), nRow()) or vb.visCube().shape() The latter comes from the VisIter state...the former be careful... For example VisBuffAccumulator changes these in an unconnected fashion; without updating fillnrow datacube shape etc etc. You are warned nrow_p etc are public variables effectively (despite being declared private) so it can be changed anywhere the code uses a vb, intentionally or accidentally.
