Class AbstractSingleSourceFilter

java.lang.Object
  edu.swri.swiftvis.filters.AbstractSingleSourceFilter

All Implemented Interfaces:

DataSink, DataSource, Filter, GraphElement, java.io.Serializable

Direct Known Subclasses:

ClusterFilter, ConstantsFilter, CoordConvertFilter, CountRebinFilter, ElementTableEditor, GroupNumberingFilter, LinearFitFilter, MassFilter, MovieFilter, RegionSelectionFilter, RotationFilter, SliceSelectionFilter, SortFilter, SyMBAMassFilter, ThinningFilter, WakePeakFilter

public abstract class AbstractSingleSourceFilter
extends java.lang.Object
implements Filter

This abstract class is intended to help people extend SwiftVis. Most filters that can only take data from a single source should extend this class instead of directly implementing the Filter interface.

Constructor Detail

AbstractSingleSourceFilter

protected AbstractSingleSourceFilter()

AbstractSingleSourceFilter

protected AbstractSingleSourceFilter(AbstractSingleSourceFilter c,
                                     java.util.List<GraphElement> l)

This constructor is used by the copy method of subclasses.

Parameters:

c - The filter we are copying.

l - A list of other elements being copied. Only links to these should go through.

Method Detail

validInput

public boolean validInput(DataSource ds)

Specified by:

validInput in interface DataSink

addInput

public void addInput(DataSource in)

Specified by:

addInput in interface DataSink

removeInput

public void removeInput(DataSource in)

Specified by:

removeInput in interface DataSink

moveUpInput

public void moveUpInput(int index)

Specified by:

moveUpInput in interface DataSink

getSource

public DataSource getSource(int which)

Specified by:

getSource in interface DataSink

getNumSources

public int getNumSources()

Specified by:

getNumSources in interface DataSink

sourceAltered

public void sourceAltered(DataSource source)

Specified by:

sourceAltered in interface DataSink

addOutput

public void addOutput(DataSink sink)

Specified by:

addOutput in interface DataSource

removeOutput

public void removeOutput(DataSink sink)

Specified by:

removeOutput in interface DataSource

getNumOutputs

public int getNumOutputs()

Specified by:

getNumOutputs in interface DataSource

getOutput

public DataSink getOutput(int which)

Specified by:

getOutput in interface DataSource

getBounds

public java.awt.Rectangle getBounds()

Specified by:

getBounds in interface GraphElement

translate

public void translate(int dx,
                      int dy)

Specified by:

translate in interface GraphElement

clearData

public void clearData()

Description copied from interface: GraphElement

This method does what the name implies, it clears out data vectors. It is used for saving templates which shouldn't have the data in them.

Specified by:

clearData in interface GraphElement

getPaint

public java.awt.Paint getPaint()

drawNode

public void drawNode(java.awt.Graphics2D g)

Specified by:

drawNode in interface GraphElement

getElement

public DataElement getElement(int i)

Description copied from interface: DataSource

Returns the specified data element for this source. I'm using this instead of an iterator because direct access is much more efficient when trying to make tables of data.

Specified by:

getElement in interface DataSource

Parameters:

i - Which data element to return. Should be between 0 and getNumElements()-1.

Returns:

The selected element.

getNumElements

public int getNumElements()

Returns the number of data elements that this source has in it. I'm using this instead of an iterator because direct access is much more efficient when trying to make tables of data.

Specified by:

getNumElements in interface DataSource

Returns:

The number of data elements in this source.

getPropertiesPanel

public javax.swing.JComponent getPropertiesPanel()

Specified by:

getPropertiesPanel in interface GraphElement

relink

public void relink(java.util.Hashtable<GraphElement,GraphElement> linkHash)

Specified by:

relink in interface GraphElement

redo

public void redo()

Specified by:

redo in interface GraphElement

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

abstractRedoAllElements

protected void abstractRedoAllElements()

localRedo

protected void localRedo()

getSourceInfoPanel

protected SourceInfoPanel getSourceInfoPanel()

getOutputInfoPanel

protected OutputInfoPanel getOutputInfoPanel()

redoAllElements

protected abstract void redoAllElements()

This method is intended to reprocess all the input elements to redo the output. It must be properly implemented by all extending classes.

setupSpecificPanelProperties

protected abstract void setupSpecificPanelProperties()

This method should add any tabbed panes to the propPanel that are specific to the given filter. This is called when the propPanel is created. After it is called, the source and output info panels are added.

doingInThreads

protected abstract boolean doingInThreads()

Method implemented to inform the AbstractFilter whether the Filter is handling threading threading or if if the AbstractFilter should put the work into the ThreadHandler itself.

Returns:

True if redoAllElements() is threaded; False if redoAllElements() should be threaded by AbstractFilter
