## com.bea.p13n.content.expression
Class SortCriteria

    java.lang.Object
      com.bea.p13n.content.expression.SortCriteria

All Implemented Interfaces:
  Cloneable, Comparable, Serializable

public class SortCriteria
extends Object
implements Cloneable, Comparable, Serializable

A class which handles the sortBy part of a Search.

This object represents a single sort criteria, which is a property name and an ascending/descending flag. The class provides a utility method to parse a sortBy string into an array of SortCriteria.

This supports standard SQL-style sort by clauses of the form:

    <propname>[ASC|DESC], ...

where ASC|DESC is optional, defaulting to ASC; also, if propname contains a ".", it assumed to be <properyset>.<propname>. Additionally, if the property name contains non-identifier characters (e.g. whitespace, double quotes, dashes, etc.), you can use the `toProperty('propname')` or `toProperty('propertyset', 'propname')` construct.

Examples of valid sortBy clauses: ``

- size
- mimeType, size DESC
- toProperty('Preferred Color') DESC, creationDate, author, modifiedDate
