XSCMLeaf

• java.lang.Object
  • com.sun.org.apache.xerces.internal.impl.dtd.models.CMNode

Fields Summary
private Object	fLeaf This is the leaf: element decl or wildcard decl.
private int	fParticleId Identify the particle: for UPA checking
private int	fPosition Part of the algorithm to convert a regex directly to a DFA numbers each leaf sequentially. If its -1, that means its an epsilon node. Zero and greater are non-epsilon positions.

Constructors Summary
public XSCMLeaf(int type, Object leaf, int id, int position) Constructs a content model leaf. // // Constructors // super(type); // Store the element index and position fLeaf = leaf; fParticleId = id; fPosition = position;

Methods Summary
protected void	calcFirstPos(com.sun.org.apache.xerces.internal.impl.dtd.models.CMStateSet toSet) // If we are an epsilon node, then the first pos is an empty set if (fPosition == -1) toSet.zeroBits(); // Otherwise, its just the one bit of our position else toSet.setBit(fPosition);
protected void	calcLastPos(com.sun.org.apache.xerces.internal.impl.dtd.models.CMStateSet toSet) // If we are an epsilon node, then the last pos is an empty set if (fPosition == -1) toSet.zeroBits(); // Otherwise, its just the one bit of our position else toSet.setBit(fPosition);
final java.lang.Object	getLeaf() return fLeaf;
final int	getParticleId() return fParticleId;
final int	getPosition() return fPosition;
public boolean	isNullable() // Leaf nodes are never nullable unless its an epsilon node return (fPosition == -1);
final void	setPosition(int newPosition) fPosition = newPosition;
public java.lang.String	toString() StringBuffer strRet = new StringBuffer(fLeaf.toString()); if (fPosition >= 0) { strRet.append ( " (Pos:" + new Integer(fPosition).toString() + ")" ); } return strRet.toString();
