                CellView view,
                ViewContext context)

Method Detail

getWidth

public float getWidth(float scale)

Specified by:

getWidth in interface gzz.vob.linebreaking.HBox

getHeight

public float getHeight(float scale)

Description copied from interface: gzz.vob.linebreaking.HBox

Get the ascent of the hbox from the baseline upwards.

Specified by:

getHeight in interface gzz.vob.linebreaking.HBox

getDepth

public float getDepth(float scale)

Description copied from interface: gzz.vob.linebreaking.HBox

Get the descent of the hbox from the baseline upwards.

Specified by:

getDepth in interface gzz.vob.linebreaking.HBox

getLength

public int getLength()

Description copied from interface: gzz.vob.linebreaking.HBox

Get this box's length in characters or other units. getX(i) is valid for i < getLength().

Specified by:

getLength in interface gzz.vob.linebreaking.HBox

getX

public float getX(int i,
                  float scale)

Description copied from interface: gzz.vob.linebreaking.HBox

Get the position after a unit (e.g. character) inside this HBox.

Specified by:

getKey

public java.lang.Object getKey()

Description copied from interface: gzz.vob.linebreaking.HBox

The key for this HBox. XXX

Specified by:

getKey in interface gzz.vob.linebreaking.HBox

place

public void place(VobScene vs,
                  int coordsys,
                  float scale)

Description copied from interface: gzz.vob.linebreaking.HBox

Place the contents of this box into a given coordsys. This function may change this HBox and place it into the coordsys: the following is a legal implementation:

	public class FooBox extends Vob implements HBox {
		float scale;
   	...
   	...
		public void place(VobScene vs, int cs, float scale) {
			this.scale = scale;
			vs.map.put(this, cs);
		}
  }
 

Specified by:

place in interface gzz.vob.linebreaking.HBox

setPrev

public void setPrev(gzz.vob.linebreaking.HBox b)

Description copied from interface: gzz.vob.linebreaking.HBox

Set the preceding HBox. This is useful for beaming where shared sequences should be truly shared.

Specified by:

setPrev in interface gzz.vob.linebreaking.HBox
