Constructor Detail

RejectParser

public RejectParser(ProtocolDataUnit initProtocolDataUnit)

Default constructor, creates a new, empty RejectParser object.

Parameters:

initProtocolDataUnit - The reference ProtocolDataUnit instance, which contains this RejectParser subclass object.

Method Detail

getDataSequenceNumber

public final int getDataSequenceNumber()

This field is only valid if the rejected PDU is a Data/R2T SNACK and the Reject reasonCode code is "Protocol error" (see Section 10.16 SNACK Request). The DataSN/R2TSN is the next Data/R2T sequence number that the target would send for the task, if any.

Returns:

The data sequence number of this RejectParser object.

getReasonCode

public final RejectParser.ReasonCode getReasonCode()

Returns the reject reasonCode code of this RejectParser object.

Returns:

The reasonCode code of this RejectParser object.

toString

public final String toString()

This method concatenate all the fields of a derived parser to allow an easy generation of debug informations.

Overrides:

toString in class TargetMessageParser

Returns:

The debug formatted string.

getDataSegmentFormat

public final DataSegmentFactory.DataSegmentFormat getDataSegmentFormat()

If this method returns true, hen it indicates that the data segment data is interpreted as binary data. Else the data segment data must be interpreted as Text Format.

Specified by:

getDataSegmentFormat in class AbstractMessageParser

Returns:

Returns a format defined by the DataSegmentFormat enumeration.

See Also:

DataSegmentFactory.DataSegmentFormat

clear

public final void clear()

This method sets all settings to their initial values.

Overrides:

clear in class TargetMessageParser

deserializeBytes1to3

protected final void deserializeBytes1to3(int line)
                                   throws InternetSCSIException

Parse the bytes 1 till 3 in the Basic Header Segment.

Overrides:

deserializeBytes1to3 in class TargetMessageParser

Parameters:

line - The actual line

Throws:

InternetSCSIException - If any violation of the iSCSI-Standard emerge.

deserializeBytes36to39

protected final void deserializeBytes36to39(int line)
                                     throws InternetSCSIException

Parse the bytes 36 till 39 in the Basic Header Segment.

Overrides:

deserializeBytes36to39 in class TargetMessageParser

Parameters:

line - The actual line

Throws:

InternetSCSIException - If any violation of the iSCSI-Standard emerge.

checkIntegrity

protected final void checkIntegrity()
                             throws InternetSCSIException

This method checks, if all parsed fields are valid. Because there are several fields, which are reserved for future versions, and these must be zero. Is this the case an exception will be thrown.

Specified by:

checkIntegrity in class AbstractMessageParser

Throws:

InternetSCSIException - If the integrity is violated.

serializeBytes1to3

protected final int serializeBytes1to3()

Serializes the bytes 1 till 3 in the Basic Header Segment.

Overrides:

serializeBytes1to3 in class TargetMessageParser

Returns:

The serialized byte representation.

serializeBytes36to39

protected final int serializeBytes36to39()

Serializes the bytes 36 till 39 in the Basic Header Segment.

Overrides:

serializeBytes36to39 in class TargetMessageParser

Returns:

The serialized byte representation.
