Method Detail

getErlang

public OtpErlangObject getErlang(boolean compressed)

Description copied from interface: Operation

Gets the erlang representation of the operation.

Specified by:

getErlang in interface Operation

Parameters:

compressed - whether the value part in the term should be encoded, i.e. compressed into an Erlang binary, or not

Returns:

erlang representation for api_tx:req_list

getKey

public OtpErlangString getKey()

Description copied from interface: Operation

Gets the key the operation is working on (if available)

Specified by:

getKey in interface Operation

Returns:

the key or null

setResult

public void setResult(OtpErlangObject resultRaw,
             boolean compressed)

Description copied from interface: Operation

Sets the raw erlang result value. It can be processed using Operation.processResult().

Specified by:

setResult in interface Operation

Parameters:

resultRaw - the result

compressed - whether the value inside the result is compressed or not

getResult

public OtpErlangObject getResult()

Description copied from interface: Operation

Gets the (raw Erlang) result set via Operation.setResult(OtpErlangObject, boolean).

Specified by:

getResult in interface Operation

Returns:

the result object or null if not set

getResultCompressed

public boolean getResultCompressed()

Description copied from interface: Operation

Determines if the result set via Operation.setResult(OtpErlangObject, boolean) is compressed or not.

Specified by:

getResultCompressed in interface Operation

Returns:

true if compressed, false otherwise, undefined if no result was set

processResult

public Object processResult()
                     throws AbortException,
                            UnknownException

Description copied from interface: Operation

Processes the result set by Operation.setResult(OtpErlangObject, boolean). Note: the created value is not cached!

Specified by:

processResult in interface Operation

Returns:

a (potentially) read value (may be null)

Throws:

AbortException - if a commit failed

UnknownException - if any other error occurs

toString

public String toString()

Overrides:

toString in class Object

processResult_commit

public static final void processResult_commit(OtpErlangObject received_raw,
                        boolean compressed)
                                       throws AbortException,
                                              UnknownException

Processes the received_raw term from erlang interpreting it as a result from a commit operation. 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 commit failed

UnknownException - if any other error occurs
