Class WideGlue

java.lang.Object
  org.extex.core.glue.WideGlue

Direct Known Subclasses:

DeltaNode

public class WideGlue
extends java.lang.Object

This class provides an implementation for glue. In contrast to Glue a full vector of all infinities for the stretchable and shrinkable components are stored. Glue stores only the highest factor. In case that during computations – addition or subtraction – this component reduces to zero the next lower infinity order should determine the value.

Creates a new object.

Method Detail

add

public void add(FixedDimen dimen)

Add some length to the natural length.

Parameters:

dimen - the length to add

add

public void add(FixedGlue glue)

Add some more glue to this one.

Parameters:

glue - the glue to add

add

public void add(WideGlue glue)

Add some more glue to this one.

Parameters:

glue - the glue to add

addStretch

public void addStretch(FixedDimen s)

Add some length to the stretch.

Parameters:

s - the length to add

getLength

public FixedDimen getLength()

Getter for the natural length.

Returns:

the natural length

getShrink

public FixedGlueComponent getShrink()

Getter for the shrink.

Returns:

the shrink as glue component

getStretch

public FixedGlueComponent getStretch()

Getter for the stretch.

Returns:

the stretch component

set

public void set(FixedGlue glue)

Setter for the glue value in all three components

Parameters:

glue - the glue to copy

set

public void set(FixedDimen len)

Setter for the length. The stretch and shrink components are set to zero.
