Method Detail

getFilter

Filter getFilter()

Returns the Filter from which this instance obtains its data. If there is no such filter, i.e., if this is the first object in the filter pipeline, this method returns null.

Returns:

the filter from which data is obtained, or null

getFlavor

IOFlavor getFlavor()

Returns the IOFlavor of this data source. Depending on the flavor, this instance has to implement corresponding subinterfaces of FilterSource.

Returns:

the flavor of the data

getMetaData

<V> V getMetaData(FilterSource.MetaDataKey<V> key,
                V defaultValue)

getSystemId

java.lang.String getSystemId()

Returns a system id which identifies this source.

Returns:

system id

initProgressMonitor

void initProgressMonitor(ProgressMonitor monitor)

setMetaData

<V> void setMetaData(FilterSource.MetaDataKey<V> key,
                   V value)

setProgress

void setProgress(java.lang.String text,
               float progress)
