Method Detail

encodeSearchKey

byte[] encodeSearchKey(S storable)

Build a search key by extracting all the desired properties from the given storable.

Parameters:

storable - extract a subset of properties from this instance

Returns:

raw search key

encodeSearchKey

byte[] encodeSearchKey(S storable,
                     int rangeStart,
                     int rangeEnd)

Build a search key by extracting all the desired properties from the given storable.

Parameters:

storable - extract a subset of properties from this instance

rangeStart - index of first property to use. Its value must be less than the count of properties used by this factory.

rangeEnd - index of last property to use, exlusive. Its value must be less than or equal to the count of properties used by this factory.

Returns:

raw search key

encodeSearchKey

byte[] encodeSearchKey(java.lang.Object[] values)

Build a search key by supplying property values without a storable.

Parameters:

values - values to build into a key. It must be long enough to accommodate all of properties used by this factory.

Returns:

raw search key

encodeSearchKey

byte[] encodeSearchKey(java.lang.Object[] values,
                     int rangeStart,
                     int rangeEnd)

Build a search key by supplying property values without a storable.

Parameters:

values - values to build into a key. The length may be less than the amount of properties used by this factory. It must not be less than the difference between rangeStart and rangeEnd.

rangeStart - index of first property to use. Its value must be less than the count of properties used by this factory.

rangeEnd - index of last property to use, exlusive. Its value must be less than or equal to the count of properties used by this factory.

Returns:

raw search key

encodeSearchKeyPrefix

byte[] encodeSearchKeyPrefix()

Returns the search key for when there are no values. Returned value may be null.
