All Implemented Interfaces:
Discardable, Node, java.io.Serializable

public class BeforeMathNode
extends AbstractNode
implements Discardable

This node represents a TeX "math" node with the subtype "before".

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

BeforeMathNode

public BeforeMathNode(FixedDimen mathsurround)
Creates a new object.

Parameters:
mathsurround - the width to add after the math
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 AbstractNode
Parameters:
sb - the output string buffer
prefix - the prefix string inserted at the beginning of each line
breadth - the breadth
depth - the depth

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
