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.

WideGlue

public WideGlue()

Creates a new object.

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(ImmutableDimen len)

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

Parameters:

len - the length

set

public void set(WideGlue wg)

Setter for the glue value in all three components

Parameters:

wg - the glue to copy

subtract

public void subtract(FixedGlue glue)

Subtract some more glue to this one.

Parameters:

glue - the glue to add

subtract

public void subtract(FixedDimen dimen)

Subtract some length from this one.

Parameters:

Subtract some glue from this one.

Parameters:

glue - the glue to subtract

toGlue

public Glue toGlue()

Get the Glue representation for this instance. The stretch and shrink components are reduced to the highest order coefficients.

Returns:

the Glue representation of this instance
