Method Detail

getCacheSize

public long getCacheSize()

Deprecated.

Returns the cache size. The cache size defines how often the sequencer will allocate a block of unique sequence numbers from the database. When the sequencer exhausts its supplied of allocated numbers, it will allocate a new sequence of numbers from the database.

Returns:

The cache size.

getCurrent

public long getCurrent(Connection databaseConnection)
                throws SQLException

Deprecated.

Gets the current sequence number associated with this sequencer.

Parameters:

databaseConnection - The database connection used to generate the next sequence number.

Throws:

SQLException - on error.

SQLException

getIncrementAmount

public long getIncrementAmount()

Deprecated. Replaced by getCacheSize

Returns the increment amount. The increment amount defines how often the sequencer will allocate a block of unique sequence numbers from the database. When the sequencer exhausts its supplied of allocated numbers, it will allocate a new sequence of numbers from the database.

Returns:

The increment amount.

getCacheSize()

getNext

public long getNext(Connection databaseConnection)
             throws SQLException

Deprecated.

Gets the next sequence number using the supplied database connection.

Parameters:

databaseConnection - The database connection used to generate the next sequence number.

Throws:

SQLException - on error.

SQLException

getSequenceName

public String getSequenceName()

Deprecated.

Returns the name of the sequence that is managed by this sequencer.

Returns:

The sequence name.

getSequencerName

public String getSequencerName()

Deprecated.

Returns the name of this sequencer.

Returns:

The sequencer name.

getStepSize

public long getStepSize()

Deprecated.

Returns the step size. The step size determines the difference between the values returned from successive calls to getNext().

Returns:

The step size.

setCacheSize

public void setCacheSize(long cacheSize)

Deprecated.

Sets the cache size. The cache size defines how often the sequencer will allocate a block of unique sequence numbers from the database. When the sequencer exhausts its supplied of allocated numbers, it will allocate a new sequence of numbers from the database.

Parameters:

cacheSize - The cache size.

setIncrementAmount

public void setIncrementAmount(long incrementAmount)

Deprecated. Replaced by setCacheSize

Sets the increment amount. The increment amount defines how often the sequencer will allocate a block of unique sequence numbers from the database. When the sequencer exhausts its supplied of allocated numbers, it will allocate a new sequence of numbers from the database.

Parameters:

incrementAmount - The increment amount.

setCacheSize(long)

setSequenceName

public void setSequenceName(String sequenceName)

Deprecated.

Sets the name of the sequence that is managed by this sequencer.

Parameters:

sequenceName - The new sequence name.

setSequencerName

public void setSequencerName(String sequencerName)

Deprecated.

Sets the name of this sequencer.

Parameters:

sequencerName - The new sequencer name.

setStepSize

public void setStepSize(long stepSize)

Deprecated.

Sets the step size. The step size determines the difference between the values returned from successive calls to getNext().

Parameters:

stepSize - The step size.
