Method Detail

encode

public static com.ericsson.otp.erlang.OtpErlangObject encode(com.ericsson.otp.erlang.OtpErlangObject value)

Encoded the given erlang object to a binary the same way as rdht_tx:encode_value/1.

Parameters:

value - the decoded value

Returns:

the encoded value

decode

public static com.ericsson.otp.erlang.OtpErlangObject decode(com.ericsson.otp.erlang.OtpErlangObject value)
                                                      throws com.ericsson.otp.erlang.OtpErlangDecodeException

Decodes the given Erlang object from a binary to the according OtpErlangObject the same way as rdht_tx:decode_value/1.

Parameters:

value - the encoded value

Returns:

the decoded value

Throws:

com.ericsson.otp.erlang.OtpErlangDecodeException - if decoding fails

checkResult_failAbort

public static final void checkResult_failAbort(com.ericsson.otp.erlang.OtpErlangObject received_raw,
                                               boolean compressed)
                                        throws AbortException,
                                               UnknownException

Processes the received_raw term from erlang and if it is a {fail, abort, KeyList}, issues an AbortException. NOTE: this method should not be called manually by an application and may change without prior notice!

Parameters:

received_raw - the object to process

compressed - whether the transfer of values is compressed or not

Throws:

AbortException - if the commit of the write failed

UnknownException - if any other error occurs
