All Implemented Interfaces:
Discardable, Node, java.io.Serializable, SkipNode
Direct Known Subclasses:
SpaceNode
public class GlueNode
extends AbstractExpandableNode
implements SkipNode, Discardable

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

GlueNode

public GlueNode(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

GlueNode

public GlueNode(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
Method Detail

toString

public void toString(java.lang.StringBuffer sb,
                     java.lang.String prefix,
                     int breadth,
                     int depth)
This method puts the printable representation into the string buffer. This is meant to produce a short form only as it is used in error messages to the user.

Specified by:
toString in interface Node
Overrides:
toString in class AbstractNode
Parameters:
sb - the output string buffer
prefix - the prefix string inserted at the beginning of each line
breadth - the breadth (ignored)
depth - the depth (ignored)

toText

public void toText(java.lang.StringBuffer sb,
                   java.lang.String prefix)
Description copied from interface: Node
This method puts the printable representation into the string buffer. This is meant to produce a short form only as it is used in error messages to the user.

Specified by:
toText in interface Node
Overrides:
toText in class AbstractNode
Parameters:
sb - the output string buffer
prefix - the string prepended to each line of the resulting text
See Also:
Node.toText(java.lang.StringBuffer, java.lang.String)

visit

public java.lang.Object visit(NodeVisitor visitor,
                              java.lang.Object value)
                       throws GeneralException
Description copied from interface: Node
This method provides an entry point for the visitor pattern.

Specified by:
visit in interface Node
Parameters:
visitor - the visitor to apply
value - the argument for the visitor
Returns:
the result of the method invocation of the visitor
Throws:
GeneralException - in case of an error
