Enum Constant Detail

STOPPED

public static final HandlerState STOPPED

CmeMdHandler is stopped.

SECURITY_DEFINITIONS_RECOVERY_STARTED

public static final HandlerState SECURITY_DEFINITIONS_RECOVERY_STARTED

Subscribed to Instrument Definition stream.

SECURITY_DEFINITIONS_RECOVERY_FINISHED

public static final HandlerState SECURITY_DEFINITIONS_RECOVERY_FINISHED

All instruments are received.

BOOKS_RESYNCHRONIZATION_STARTED

public static final HandlerState BOOKS_RESYNCHRONIZATION_STARTED

The correct books state is lost.

CmeMdHandler switches to this state when it joins the market and the initial books state is built from MarketDataSnapshotFullRefresh (W) messages or when the TcpReplay is not used and the message sequence number gap is detected, so the book state should be re-built from MarketDataSnapshotFullRefresh (W) messages again.

It should be assumed at this point that all books maintained in the CmeMdHandler may no longer have the correct, latest state maintained by CME, so they are cleared.

BOOKS_RESYNCHRONIZATION_FINISHED

public static final HandlerState BOOKS_RESYNCHRONIZATION_FINISHED

The latest books state is restored.

CmeMdHandler switches to this state when the the latest books state is restored from MarketDataSnapshotFullRefresh (W() messages (all snapshot data is retrieved).

It should be assumed at this point that all books maintained in the CmeMdHandler have the correct, latest state maintained by CME.

TCP_REPLAY_STARTED

public static final HandlerState TCP_REPLAY_STARTED

TCP Replays is started.

TCP_REPLAY_FINISHED

public static final HandlerState TCP_REPLAY_FINISHED

TCP Replays is finished.

STARTED

public static final HandlerState STARTED

Handler started but feeds stopped.

Method Detail

values

public static HandlerState[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (HandlerState c : HandlerState.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static HandlerState valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getValue

public int getValue()

Get int value.

Returns:

int value.

forValue

public static HandlerState forValue(int value)

Convert int to enumeration.

Parameters:

value - int value.

Returns:

enumeration for this int value.
