Returns the entity matching the criteria or null if none matches

Parameters:

typeNames - - list of types to use for lookup

source - - the source against which we want to match

list - of entities in which to search

Returns:

entity matching type and source

getMatchingProperties

protected abstract InstanceProperties getMatchingProperties(T source)

Parameters:

source - we want to match against

Returns:

the properties to use from source bean to match an entity against
