Detailed Description

(Minimal) DisplayMethod for MSAsRaster.

Prerequisite

• MSAsRaster
• CachingDisplayMethod

Etymology

"MSAsRasterDM" is a implementation of a CachingDisplayMethod for MSAsRaster .

Synopsis

MSAsRasterDM a minimal skeleton; it is implemented in its entirety here. Its only purpose is to hold the cached drawlist and use it when appropriate via the mechanism and data structure implemented on the CachingDisplayMethod level. MSAsRasterDM just turns the draw request back over to MSAsRaster, since that's where the necessary data is.

This 'minimal' CachingDisplayMethod could be adapted and reused by any other CachingDisplayData that wanted to do its own drawing.

Constructor & Destructor Documentation

casa::MSAsRasterDM::MSAsRasterDM ( WorldCanvas *  wc, AttributeBuffer *  wchAttrs, AttributeBuffer *  ddAttrs, CachingDisplayData *  dd  )

inline

Constructor.

The parameters contain state that determines what should be drawn.

Definition at line 1437 of file MSAsRaster.h.

virtual casa::MSAsRasterDM::~MSAsRasterDM ( )

inlinevirtual

Destructor.

inlineprivate

Default and copy constructors, and the assignment operator, are mon-functional and should not be used.

Do not make copies of DisplayMethod objects, or pass them by value; use references or pointers instead.

Member Function Documentation

virtual casacore::Bool casa::MSAsRasterDM::drawIntoList ( Display::RefreshReason  reason, WorldCanvasHolder &  wcHolder  )

inlineprotectedvirtual

The base CachingDM takes care of using any cached drawlist.

When this method is called, we know that no drawlist applies, and that we must actually send drawing commands to the WC (though technically, they might not actually be going into a drawlist). This skeleton DM just hands the drawing task back to the DD, where all the data has been created and maintained anyway.

Implements casa::CachingDisplayMethod.
