Method Detail

canSupport

boolean canSupport(Expressivity expressivity)

Check if this safety checker can be used with the specified expressivity.

Parameters:

expressivity - Expressivity of the KB where safety check will be performed

Returns:

true if this safety checker can be used with the specified expressivity

boolean isSafe(aterm.ATermAppl c,
               Individual ind)

Returns if a previously cached satisfiability result is safe to reuse for a given concept and node in the completion graph.

Parameters:

c - The concept for which we want to reuse previously cached satisfiability result

ind - The node in the completion graph represented by the concept

Returns:

true if a previously cached satisfiability result is safe to reuse
