Class BeforeMathNode

java.lang.Object
  org.extex.typesetter.type.node.AbstractNode
      org.extex.typesetter.type.node.BeforeMathNode

All Implemented Interfaces:

java.io.Serializable, Discardable, Node

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.

Constructor Detail

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

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
