java.lang.String	getUserID() Gets The identification of the user owning the new transaction
boolean	isAutoCommit() Checks whether, for read-only transactions, the read locks acquired by the server can be released after each individual statement executed by the transaction
boolean	isCaptureDDL() Gets the flag indicating whether the server's DDL capture facility should be activated for this transaction
boolean	isReadOnlyTransaction() Checks whether or not the new transaction is a read-only one, i.e.

Method Detail

getSignature

public final byte[] getSignature()

Gets the signature computed by the user

Returns:

the signature computed by the user

getUserAuthenticationAlgorithm

public final java.lang.String getUserAuthenticationAlgorithm()

Gets the name of the user authentication algorithm to be used by the server if the decides that it will do user authentication itself

Returns:

the name of the user authentication algorithm to be used by the server if the decides that it will do user authentication itself

getUserID

public final java.lang.String getUserID()

Gets The identification of the user owning the new transaction

Returns:

The identification of the user owning the new transaction

isAutoCommit

public final boolean isAutoCommit()

Checks whether, for read-only transactions, the read locks acquired by the server can be released after each individual statement executed by the transaction

Returns:

true if, for read-only transactions, the read locks acquired by the server can be released after each individual statement executed by the transaction

isCaptureDDL

public final boolean isCaptureDDL()

Gets the flag indicating whether the server's DDL capture facility should be activated for this transaction

Returns:

the flag indicating whether the server's DDL capture facility should be activated for this transaction

isReadOnlyTransaction

public final boolean isReadOnlyTransaction()

Checks whether or not the new transaction is a read-only one, i.e. whether it will or will not attempt updates to the database

Returns:

true if the new transaction is a read-only one, i.e. if it will not attempt updates to the database

isUserAuthenticatedByClient

public final boolean isUserAuthenticatedByClient()

Gets the flag indicating whether the user identified by getUserID() has been authenticated by the client, meaning that if the server trusts the client, the server needn't do user authentication of its own.

Returns:

true if the user identified by getUserID() has been authenticated by the client, meaning that if the server trusts the client, the server needn't do user authentication of its own.

getSnapShotIsolationMode

public final SnapShotIsolationMode getSnapShotIsolationMode()

Gets the snapshot isolation mode that this readonly transaction is to run under (snapshot isolation does not apply to update transactions. Update transactions always run in SnapShotIsolatinMode.OFF).

Returns:

Gets the snapshot isolation mode that this readonly transaction is to run under (snapshot isolation does not apply to update transactions. Update transactions always run in SnapShotIsolatinMode.OFF).
