Class FAM_Session

createFabricExternalSession

FAM_Session createFabricExternalSession(String lockId,
                                        String version)

This function creates a FAM session. Use this function when accessing the FAM API outside a fabric task.

getLockID

String getLockId( )

This function returns the lock identifier.

getVersion

String getVersion( )

This function returns the session version.

getLeaseTimeout

int getLeaseTimeout( )

This function returns the amount of time the data is locked.

setLeaseTimeout

void setLeaseTimeout(int leaseTimeout)

This function sets the maximum amount of time, in milliseconds, the data is locked.

getSpacesTouchedCount

int getSpacesTouchedCount( )

This function returns the number of spaces accessed during the session.

commit

void commit( )

This function commits the data manipulations performed in the session.

rollback

void rollback( )

This function deletes the data manipulations performed in the session and returns the data to the last commit.

Note. The FAM does not keep past versions of the data. When data is locked, a copy is created. Once data has been committed, by sending the commit function or by the successful completion of a task, that copy is deleted. You can not go back to a previous version of data.

commitPrep

void commitPrep( )

This function is the first phase of a two-phase commit. To complete the commit you must call the commit function.

invalidate

void invalidate( )

This function executes a rollback without releasing the lock.
