Method Detail

fireDatamixerEvent

public void fireDatamixerEvent(int event)
                        throws DatamixerException

Calls handleDatamixerEvent on listeners. If there are no listeners, then calls fireDatamixerEvent on referenced iterator.

Specified by:

fireDatamixerEvent in interface DatamixerEventGenerator

Overrides:

fireDatamixerEvent in class DatamixerIterator

Throws:

DatamixerException

doInitialize

protected void doInitialize()
                     throws DatamixerException

Initialization.

Overrides:

doInitialize in class DatamixerIterator

Throws:

DatamixerException

getCollection

public DatamixerCollection getCollection()

Returns this iterator's collection.

Overrides:

getCollection in class DatamixerIterator

Returns:

this iterator's collection.

getDataType

public int getDataType()

Returns the datatype. Datatypes are defined in java.sql.Types.

Overrides:

getDataType in class DatamixerIterator

doGetCurrentValue

protected Value doGetCurrentValue()

Returns the current value.

Specified by:

doGetCurrentValue in class DatamixerIterator

Returns:

the current value.

getFormat

public java.text.Format getFormat(java.lang.String pattern)

Returns an appropriate Format object.

Overrides:

getFormat in class DatamixerIterator

doDone

protected boolean doDone()
                  throws DatamixerException

Returns true if generation has finished.

Overrides:

doDone in class DatamixerIterator

doGenerate

protected void doGenerate()
                   throws DatamixerException

Generate the next element in the collection.

Overrides:

doGenerate in class DatamixerIterator

Throws:

DatamixerException

doReset

protected void doReset()
                throws DatamixerException

Resets the generator to an initial state.

Overrides:
