getMapping

public AMapping getMapping(ACache source,
                           ACache target,
                           String sourceVar,
                           String targetVar,
                           String expression,
                           double threshold)

Description copied from interface: IMapper

Returns a mapping given a source, a target knowledge base and a link specification.

Parameters:

source - source cache

target - target cache

sourceVar - source property variable

targetVar - size property variable

expression - metric expression of link specification

threshold - threshold of link specification

Returns:

a mapping, the resulting mapping

getRuntimeApproximation
