Class SyntaxLabels

java.lang.Object

org.apache.jena.riot.system.SyntaxLabels

public class SyntaxLabels
extends Object

Factory for default policies for syntax labels to and from nodes For label to node (parsing) we use a scalable hashing scheme (MD5 of a seed and the label)

For node to label (pretty labels output), we use a unique tracking scheme. Fully scalable writers use different polices and don't have short, pretty bNode labels.

These should be used pairs:

     createNodeToLabel , createLabelToNode
     createNodeToLabelRT , createLabelToNodeRT
     createNodeToLabelAsGiven , createLabelToNodeAsGiven
 

"AsGiven" assumes that he label is valid syntax for the usage, no checking.
"RT" encodes the label into characters 0-9,A-Z.
