Constructor Detail

TableRequest

public TableRequest(Target<?> target,
                    OID[] columnOIDs,
                    TableListener listener,
                    java.lang.Object userObject,

                    TableUtils.SparseTableMode sparseTableMode)

Method Detail

getSparseTableMode

public TableUtils.SparseTableMode getSparseTableMode()

getNumLexicographicErrors

public int getNumLexicographicErrors()

Gets the number of lexicographic errors that occurred during request processing. Any errors occurred on the same row will be count as one error.

Returns:

the number of rows returned by the agent in wrong lexicographic order (i.e. not strictly ascending).

Since:

2.5.11

sendNextChunk

public boolean sendNextChunk()

sendRequest

protected void sendRequest(PDU pdu,
