Field Detail

CONN_PARAM_STATE_KEY_PERSISTENCE

static final java.lang.String CONN_PARAM_STATE_KEY_PERSISTENCE

The name of the parameter which value specifies the method, used for storing the StateKey.

PARAM_VAL_AFTER_READ

static final java.lang.String PARAM_VAL_AFTER_READ

Possible String value of the CONN_PARAM_STATE_KEY_PERSISTENCE parameter. If that parameter have this value then the getStateKeySaveMethod() will return SAVE_STATE_AFTER_READ (0)

Constant Field Values

PARAM_VAL_END_OF_CYCLE

static final java.lang.String PARAM_VAL_END_OF_CYCLE

Possible String value of the CONN_PARAM_STATE_KEY_PERSISTENCE parameter. If that parameter have this value then the getStateKeySaveMethod() will return SAVE_STATE_END_OF_CYCLE (1)

See Also:

Constant Field Values

PARAM_VAL_MANUAL

static final java.lang.String PARAM_VAL_MANUAL

Possible String value of the CONN_PARAM_STATE_KEY_PERSISTENCE parameter. If that parameter have this value then the getStateKeySaveMethod() will return SAVE_STATE_MANUAL (2)

Constant Field Values

PARAM_MERGE_CHANGELOG_AND_DATA

static final java.lang.String PARAM_MERGE_CHANGELOG_AND_DATA

Possible String value of the ChangelogConnector.PARAM_MERGE_MODE parameter. If that parameter have this value then the ChangelogConnector.defaultMerge will have a value of true.

See Also:

Constant Field Values

PARAM_MERGE_ONLY_CHANGED_DATA

static final java.lang.String PARAM_MERGE_ONLY_CHANGED_DATA

Possible String value of the ChangelogConnector.PARAM_MERGE_MODE parameter. If that parameter have this value then the ChangelogConnector.onlyChanges will have a value of true.

Constant Field Values

PARAM_MERGE_BOTH_NOT_MERGED

static final java.lang.String PARAM_MERGE_BOTH_NOT_MERGED

Possible String value of the ChangelogConnector.PARAM_MERGE_MODE parameter. If that parameter have this value then the ChangelogConnector.bothSeparated will have a value of true.

Constant Field Values

SAVE_STATE_AFTER_READ

static final int SAVE_STATE_AFTER_READ

This constant is usually used to specify that the StateKey should be persisted after each received entry.

Constant Field Values

SAVE_STATE_END_OF_CYCLE

static final int SAVE_STATE_END_OF_CYCLE

This constant is usually used to specify that the StatKey should be persisted after each AL cycle ends.

See Also:

Constant Field Values

SAVE_STATE_MANUAL

static final int SAVE_STATE_MANUAL

This constant is usually used to specify that the StatKey persistence is not done automatically by the TDI Server. The user is supposed to call the saveStateKey() method in order to store the StateKey.

Method Detail

getStateKeySaveMethod

int getStateKeySaveMethod()
                          throws java.lang.Exception

Retrieves the method for storing StateKey.

Returns:

the identifier of the method used for storing the StateKey in the TDI Store.

Throws:

java.lang.Exception - - never

See Also:

SAVE_STATE_AFTER_READ, SAVE_STATE_END_OF_CYCLE, SAVE_STATE_MANUAL

saveStateKey

void saveStateKey()
                  throws java.lang.Exception

Stores the USN values for the next synchronization. This method will skip the storing of the StateKey if the StateKey save method is set to SAVE_STATE_AFTER_READ

Throws:

java.lang.Exception - - never

getStateKeyObject

java.lang.Object getStateKeyObject()
                                   throws java.lang.Exception

Retrieves state key.

Returns:

the StateKey, wrapped in some kind of object.

Throws:

java.lang.Exception - if an error occurs.
