Constructor Detail

FilterSourceBase

public FilterSourceBase(IOFlavor flavor,
                        Registry registry,
                        ModifiableMap metaData)

Method Detail

getFilter

public final Filter getFilter()

Description copied from interface: FilterSource

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.

Specified by:

getFilter in interface FilterSource

Returns:

the filter from which data is obtained, or null

getFlavor

public final IOFlavor getFlavor()

Description copied from interface: FilterSource

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

Specified by:

getFlavor in interface FilterSource

Returns:

the flavor of the data

getMetaData

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

Specified by:

getMetaData in interface FilterSource

getRegistry

public final Registry getRegistry()

Description copied from interface: RegistryContext

Returns the Registry which is linked with this instance.

Specified by:

getRegistry in interface RegistryContext

Returns:

the registry linked with this instance

initProgressMonitor

public void initProgressMonitor(ProgressMonitor monitor)

Specified by:

initProgressMonitor in interface FilterSource

setMetaData

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

Specified by:

setMetaData in interface FilterSource

setProgress

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

Specified by:

setProgress in interface FilterSource

setProgress0

protected void setProgress0(java.lang.String text,
                            float progress)

setProgressImpl

protected void setProgressImpl(java.lang.String text,
                               float progress)

toString

public java.lang.String toString()

Overrides:
