| virtual void | valueChange () |
A base class that represents a numerical function. Some functions needs a reference point to be calculated based on differential equation. Such a function is derived from func_deriveq_base, but func_base contains interface for such a function.

A virtual function that returns the next incontinuity point after the time t. In func_base, the function always returns infinity. Reimplemented in punnets_common::func_step, punnets_common::func_delta_int, punnets_common::func_response, punnets_common::func_sine, punnets_common::func_sineshot, punnets_common::func_exp, punnets_common::func_exp_int, and punnets_common::func_exp_diff. Definition at line 96 of file func.h. References punnets_common::ntime_t.

Process the specified message at the specified time. Return true if the message is processed. In func_base, this function always returns false (processes no message). Reimplemented in punnets_common::func_deriveq_base, punnets_common::func_delta_int, punnets_common::func_sineshot, and punnets_common::func_exp_diff. Definition at line 85 of file func.h. References punnets_common::ntime_t.

An entrance to recalculate coefficient at the value change caused by some external factor. In func_base this function do nothing. This function will be defined in the derived classes with the requirement of the recalculation. Definition at line 75 of file func.h.
