TExprVirtMachOp

Summary

An operation that can be executed by a TExprVirtMach instance.

Pascal

 public TExprVirtMachOp = class(TObject);

Description

TExprVirtMachOp is the kernel of TExprVirtMach's operation. The containing class (TExprVirtMach) is just that - a container, and it just executes the instructions in order to do work.
Each instruction has a virtual Execute method, which should read input from somewhere and write output to somewhere else. Typically, the input is a series of pointers to floating-point variables, and the output is to one or more member variables. The output acts as input for instructions further on in the execution stream; for this mechanism to work, the inputs of downstream instructions must be 'wired' to the outputs of upstream instructions.
