Method Detail

getMapping

public String getMapping(Class<?> type)

Description copied from interface: MappingDiscoverer

Returns the mapping associated with the given type.

Specified by:

getMapping in interface MappingDiscoverer

Parameters:

type - must not be null.

Returns:

the type-level mapping or null in case none is present.

public String getMapping(Method method)

Description copied from interface: MappingDiscoverer

Returns the mapping associated with the given Method. This will include the type-level mapping.

Specified by:

getMapping in interface MappingDiscoverer

Parameters:

method - must not be null.

Returns:

the method mapping including the type-level one or null if neither of them present.

getMapping

public String getMapping(Class<?> type,
                         Method method)

Description copied from interface: MappingDiscoverer

Returns the mapping for the given Method invoked on the given type. This can be used to calculate the mapping for a super type method being invoked on a sub-type with a type mapping.
