## Detailed Description

Class representing a cone search in table select expression

### Intended use:

Internal

### Review Status

Reviewed By:
  UNKNOWN
Date Reviewed:
  before2004/08/25

### Prerequisite

- TableExprFuncNode

### Synopsis

The class represents a cone search. It is a specialization of the TableExprFuncNode class. Currently the implementation is straightforward, but in the future it can do smarter things. For instance:

- If the cone positions and radii are constant, one can use an integer zone number (e.g. floor(dec)) to avoid the much more expensive sine/cosine calculations. Each cone will get a minzone and maxzone value (derived from cone position and radius).
- Multiple cones can be ordered on minzone and maxzone.
