de.dante.extex.typesetter.type.node
Class AbstractExpandableNode

java.lang.Object
  extended byde.dante.extex.typesetter.type.node.AbstractNode
      extended byde.dante.extex.typesetter.type.node.AbstractExpandableNode
All Implemented Interfaces:
Node, java.io.Serializable
Direct Known Subclasses:
AlignedLeadersNode, CenteredLeadersNode, ExpandedLeadersNode, GlueNode
public abstract class AbstractExpandableNode
extends AbstractNode

This node represents a TeX "glue" node.

For the document writer it acts like a kern node. The width contains the distance to add.

The stretchability is adjusted by the typesetter and the width is adjusted accordingly.

Constructor Detail

AbstractExpandableNode

public AbstractExpandableNode(FixedDimen size,
                              boolean horizontal)
Creates a new object. The size is used to determine the width in horizontal mode and the height in vertical mode.

Parameters:
size - the actual size
horizontal - indicator that the glue is used in horizontal mode

AbstractExpandableNode

public AbstractExpandableNode(FixedGlue size,
                              boolean horizontal)
Creates a new object. The size is used to determine the width in horizontal mode and the height in vertical mode.

Parameters:
size - the actual size
horizontal - indicator that the glue is used in horizontal mode
