Class JavaIdentifierTransformer

java.lang.Object
  net.sf.json.util.JavaIdentifierTransformer

public abstract class JavaIdentifierTransformer
extends Object

Transforms a string into a valid Java identifier.
There are five predefined strategies:

• NOOP: does not perform transformation.
• CAMEL_CASE: follows the camel case convention, deletes non JavaIndentifierPart chars.
• UNDERSCORE: transform whitespace and non JavaIdentifierPart chars to '_'.
• WHITESPACE: deletes whitespace and non JavaIdentifierPart chars.
• STRICT: always throws a JSONException, does not perform transformation.
