Method Detail

getRecord

public DataRecord getRecord()

Returns actual DataRecord that shall be used for subscription. It returns null if this description does not refer to any record.

isEmpty

public boolean isEmpty()

Returns true when this descriptor was originally empty (did not contain any fields) as opposed to having an empty intersection with fields in the scheme. For subscription, this is a special signal to send all fields known in the scheme (when the receiver on the other side is schema-less).

readRecord

public RecordCursor readRecord(com.devexperts.io.BufferedInput msg,
                               RecordBuffer buffer,
                               int cipher,
                               String symbol,
                               int eventFlags)
                        throws IOException

Reads record from the specified input and adds it to the specified cursor.

Returns:

the cursor to the record that was just read or null if nothing was read (the record was skipped).

Throws:

IOException

readTime

protected long readTime(com.devexperts.io.BufferedInput msg)
                 throws IOException

Throws:

IOException

readFields

protected void readFields(com.devexperts.io.BufferedInput msg,
                          RecordCursor cur,
                          int nDesc)
                   throws IOException

Throws:

IOException

beforeField

protected void beforeField(com.devexperts.io.BufferedInput msg)

setIntValue

protected void setIntValue(RecordCursor cur,
                           int index,
                           int value,
                           com.devexperts.io.BufferedInput msg)

setLongValue

protected void setLongValue(RecordCursor cur,
                            int index,
                            long value,
                            com.devexperts.io.BufferedInput msg)

setObjValue

protected void setObjValue(RecordCursor cur,
                           int index,
                           Object value,
                           com.devexperts.io.BufferedInput msg)

writeRecord

public void writeRecord(com.devexperts.io.BufferedOutput msg,
                        RecordCursor cur,
                        int eventFlags,
                        long eventTimeSequence)
                 throws IOException

Writers record to the specified output from the specified cursor. Note, that specified eventFlags are used, not the flags from the cursor.

Throws:

IOException
