IntFlagMapping
public
final
class
IntFlagMapping
extends Object
Maps the values of an int
property to sets of string for properties that encode flags.
An InspectionCompanion
may provide an instance of this class to a PropertyMapper
for flag values packed into primitive int
properties.
Each flag has a mask and a target value, for non-exclusive flags, the target can also be used as
the mask. A given integer value is compared against each flag to find what flags are active for
it by bitwise anding it with the mask and comparing the result against the target, that is,
(value & mask) == target
.
