Class LigatureNode

java.lang.Object
  extended byde.dante.extex.typesetter.type.node.AbstractNode
      extended byde.dante.extex.typesetter.type.node.CharNode
          extended byde.dante.extex.typesetter.type.node.LigatureNode
All Implemented Interfaces:
Node, java.io.Serializable
public class LigatureNode
extends CharNode
implements Node

The ligature node represents a ligature of several characters. Ligatures can be build among characters from one common font only. The information where and how to build ligatures comes from the font. The original characters are contained in this node to be restored when required.

Constructor Detail

LigatureNode

public LigatureNode(TypesettingContext context,
                    UnicodeChar uc,
                    CharNode left,
                    CharNode right)

Method Detail

countChars

public int countChars()
Description copied from interface: Node
This method determines the number of characters contained in a node.

Specified by:
countChars in interface Node
Overrides:
countChars in class CharNode
See Also:
Node.countChars()

getChars

public CharNode[] getChars()
Description copied from interface: Node
Getter for the array of characters enclosed in this node.

Specified by:
getChars in interface Node
Overrides:
getChars in class CharNode
See Also:
Node.getChars()

getLeft

public CharNode getLeft()
Getter for left node.

Returns:
the left node

getRight

public CharNode getRight()
Getter for right node.

Returns:
the right node

toString

public void toString(java.lang.StringBuffer sb,
                     java.lang.String prefix,
                     int breadth,
                     int depth)
This method returns the printable representation. 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 CharNode
Parameters:
sb - the output string buffer
prefix - the prefix string inserted at the beginning of each line
breadth - the breadth
depth - the depth
