Protected Attributes | |
int | error |
Latest error, initialized to E_NOERROR in constructor. More... | |
Solver interface supporting storage and description of the latest error.
Error codes: Zero (0) indicates no error, positive error codes indicate more of a warning (e.g. a degraded solution, but motion can continue), and negative error codes indicate failure (e.g. a singularity, and motion can not continue).
Error codes between -99 and +99 (inclusive) are reserved for system-wide error codes. Derived classes should use values > +100, and < -100.

Update the internal data structures. This is required if the number of segments or number of joints of a chain/tree have changed. This provides a single point of contact for solver memory allocations.
