Constructor Detail

AdjustableSwath

public AdjustableSwath(Voxel start,
                       Voxel end)

Create a new Swath given its beginning and ending Voxel. The dimensionality will be set to the maximum of that for the two Voxels given; positions from any missing axes will be set to zero.

AdjustableSwath

public AdjustableSwath(int naxes)

Create a default Swath of zero length

Parameters:

naxes - the dimensionality of the space.

AdjustableSwath

public AdjustableSwath()

Create a default Swath of zero length in a 2-dimensional space

AdjustableSwath

public AdjustableSwath(Swath in)

Create a Swath that is a copy of another Swath. This constructor is useful when converting an immutable swath to a mutable one.

Method Detail

isMutable

public boolean isMutable()

return true if the paramters of this Volume can change. This implementation always returns true.

Overrides:

isMutable in class Swath

getMonitor

public java.util.Observable getMonitor()

return an Observable monitor for listening for changes to this Volume. Clients interested in such changes can add themselves to the Observable returned by this method. They will be notified when any of the Volume parameters position change, passing this Volume as an argument to the Observers' update() method.

Overrides:

getMonitor in class Swath

setStart

public void setStart(Voxel vox)

set the starting position. Missing axes will be set to zero

setStart

public void setStart(int[] pos)

set the starting position. Missing axes will be set to zero

setStart

public void setStart(double[] pos)

set the starting position. Missing axes will be set to zero

setStart

public void setStart(int axis,
                     int pos)

set a component of the starting position. Missing axes will be set to zero.

setStart

public void setStart(int axis,
                     double pos)

set a component of the starting position. Missing axes will be set to zero.

setEnd

public void setEnd(Voxel vox)

set the ending position. Missing axes will be set to zero

setEnd

public void setEnd(int[] pos)

set the ending position. Missing axes will be set to zero

setEnd

public void setEnd(double[] pos)

set the ending position. Missing axes will be set to zero

setEnd

public void setEnd(int axis,
                   int pos)

set a component of the ending position. Missing axes will be set to zero.

setEnd

public void setEnd(int axis,
                   double pos)

set a component of the ending position. Missing axes will be set to zero.
