function MamaMsgQualifier

inline MamaMsgQualifier()

function MamaMsgQualifier

inline MamaMsgQualifier(
    MamaMsgQualifier qualifierFilter
)

function getIsDefinitelyDuplicate

inline boolean getIsDefinitelyDuplicate()

Return: true is a duplicate.

Return true if this message is definitely a duplicate message. This condition will not occur with the current feed handlers.

function getIsPossiblyDuplicate

inline boolean getIsPossiblyDuplicate()

Return: true if the message may be a duplicate.

Return true if this message is possibly a duplicate message. This may occur in the event of a fault tolerant feed handler take over where the feed handler replays messages to prevent gaps.

function getIsPossiblyDelayed

inline boolean getIsPossiblyDelayed()

Return: true if the message may be delayed.

Return true if the message is possibly delayed. This condition may be true during a fault-tolerant take over.

function getIsDefinitelyDelayed

inline boolean getIsDefinitelyDelayed()

Return: true if the message is delayed

Return true if the message is delayed. This condition may be true during a fault-tolerant take over.

function getIsOutOfSequence

inline boolean getIsOutOfSequence()

Return: true when the FH sends the message out of sequence.

function isValid

inline boolean isValid()

Return: true if this instance is valid

function setIsDefinitelyDuplicate

inline void setIsDefinitelyDuplicate(
    boolean value
)

Parameters:

• value for the bit .

Set the definitely duplicate bit.

function setIsPossiblyDuplicate

inline void setIsPossiblyDuplicate(
    boolean value
)

Parameters:

• value for the bit .

Set the possibly duplicate bit.

function setIsPossiblyDelayed

inline void setIsPossiblyDelayed(
    boolean value
)

Parameters:

• value for the bit .

Set the possibly delayed bit.

function setIsDefinitelyDelayed

inline void setIsDefinitelyDelayed(
    boolean value
)

Parameters:

• value for the bit .

Set the possibly delayed bit.

function setOutOfSequence

inline void setOutOfSequence(
    boolean value
)

Parameters:

• value for the bit .

Set the possibly out of sequence bit.

function setInvalid

inline void setInvalid(
    boolean value
)

Parameters:

• value value to set

set the invalid bid

function filter

inline boolean filter(
    short value
)

Parameters:

• value The value to filter.

Return: true if there is a match

Return true if any bits in value match the bits set in this qualifier.

variable POSSIBLY_DUPLICATE

static final MamaMsgQualifier POSSIBLY_DUPLICATE = new MamaMsgQualifier ((short) 0x0001);

The message is possibly a duplicate. It may be possible to make an absolute determination by comparing wSeqNum and wSrcTime with the values in the previous message.

variable DEFINITELY_DUPLICATE

static final MamaMsgQualifier DEFINITELY_DUPLICATE = new MamaMsgQualifier ((short) 0x0002);

The message is definitely a duplicate. Current feed handlers do not use this flag.

variable POSSIBLY_DELAYED

static final MamaMsgQualifier POSSIBLY_DELAYED = new MamaMsgQualifier ((short) 0x0004);

The current message may be delayed.

variable DEFINITELY_DELAYED

static final MamaMsgQualifier DEFINITELY_DELAYED = new MamaMsgQualifier ((short) 0x0008);

The current message is definitely delayed. This will be true during a fault tolerant takeover.

variable OUT_OF_SEQUENCE

static final MamaMsgQualifier OUT_OF_SEQUENCE = new MamaMsgQualifier ((short) 0x0010);

The message is out of sequence.

variable INVALID

static final MamaMsgQualifier INVALID = new MamaMsgQualifier ((short) 0x1000);

This bit is never set by the FH. It is a place holder to make this class more useful.
