class | ConstPointerToArray< Element > |
A special kind of PointerTo that stores an array of the indicated element type, instead of a single element.
This is actually implemented as an STL vector, using the RefCountObj class to wrap it up with a reference count.
We actually inherit from NodeRefCountObj these days, which adds node_ref() and node_unref() to the standard ref() and unref(). This is particularly useful for GeomVertexArrayData; other classes may or may not find this additional counter useful, but since it adds relatively little overhead (compared with what is presumably a largish array), we go ahead and add it here, even though it is inherited by many different parts of the system that may not use it.

The pointer typecast operator is convenient for maintaining the fiction that we actually have a C-style array.
It returns the address of the first element in the array, unless the pointer is unassigned, in which case it returns NULL.

Function p() is similar to the function from PointerTo.
It does the same thing: it returns the same thing as the typecast operator, above.

This method exists mainly to access the data of the array easily from a high-level language such as Python.
It replaces the contents of a portion of the vector–from element (n) through element (n + count - 1)–as a block of raw data in a string. The length of the string must be an even multiple of Element size bytes. The array may be expanded or truncated if the length of the string does not correspond to exactly count elements.
