Method Detail

createNextValue

public long createNextValue(Sequence sequence)

Description copied from interface: Sequences

Returns the next sequence value. For example: sequences.createNextValue(Sequence.withName("seq_name").setStartValue(10).setIncrement(1))

Specified by:

createNextValue in interface Sequences

Parameters:

sequence - sequence object

Returns:

next value

getCurrentValue

public long getCurrentValue(Sequence sequence)

Description copied from interface: Sequences

Returns the current value of the sequence. For some implementations Sequences.createNextValue(Sequence) must be called at least once beforehand.

Specified by:

getCurrentValue in interface Sequences

Parameters:

sequence - object Sequence

Returns:

current value

setCurrentValue

public void setCurrentValue(Sequence sequence,
                            long value)

Description copied from interface: Sequences

Set current value for the sequence. Next Sequences.getCurrentValue(Sequence) invocation will return value Next Sequences.createNextValue(Sequence) invocation will return value + increment

Specified by:

setCurrentValue in interface Sequences

Parameters:

sequence - sequence object Sequence

value - value

deleteSequence

public void deleteSequence(Sequence sequence)

Description copied from interface: Sequences

Removes sequence with specified identifier

Specified by:

deleteSequence in interface Sequences

Parameters:

sequence - sequence object Sequence

reset

public void reset()

INTERNAL. Used by tests.

getResult

protected long getResult(Sequence sequence,
                         java.lang.String sqlScript)

checkSequenceExists

protected void checkSequenceExists(Sequence sequence)

executeScript

protected java.lang.Object executeScript(Sequence sequence,
                                         java.lang.String sqlScript)

getSequenceSupport

protected SequenceSupport getSequenceSupport(Sequence sequence)

getDataStore

protected java.lang.String getDataStore(Sequence sequence)

checkSequenceName

protected void checkSequenceName(java.lang.String sequenceName)
