public class ExplicitKernNode
extends AbstractKernNode
implements Discardable

This class represents an explicit kerning node for the typesetter. From The TeXbook

A kern_node has a width field to specify a (normally negative) amount of spacing. This spacing correction appears in horizontal lists between letters like A and V when the font designer said that it looks better to move them closer together or further apart. A kern node can also appear in a vertical list, when its `width' denotes additional spacing in the vertical direction.

Constructor Detail

ExplicitKernNode

public ExplicitKernNode(FixedDimen kern,
                        boolean horizontal)
Creates a new object.

Parameters:
kern - the natural size
horizontal - the indicator that the kern works horizontally

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 exhaustive form as it is used in tracing output to the log file.

Specified by:
toString in interface Node
Overrides:
toString in class AbstractKernNode
Parameters:
sb - the output string buffer
prefix - the prefix string inserted at the beginning of each line
breadth - the breadth of the nodes to display
depth - the depth of the nodes to display
See Also:
Node.toString( java.lang.StringBuffer, java.lang.String, int, int)

toText

public void toText(java.lang.StringBuffer sb,
                   java.lang.String prefix)
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 AbstractKernNode
Parameters:
sb - the output string buffer
prefix - the prefix string inserted at the beginning of each line
