getConstraintSpaceDimension()

int getConstraintSpaceDimension

(

TransInfo *

t

)

Returns the dimension of the constraint space.

For that reason, the flags always needs to be set to properly evaluate here, even if they aren't actually used in the callback function. (Which could happen for weird constraints not yet designed. Along a path for example.)
