public class TypesHelper

extends java.lang.Object

A helper with constants for the various types and operators for configurable entity properties.

In general, there are 6 types of properties for configurable entities, represented by constants on this class. Each of those types corresponds to a Java object type as follows:

Constant Name	Constant Value	Class
BOOLEAN	0	java.lang.Boolean
INTEGER	1	java.lang.Long
FLOAT	2	java.lang.Double
TEXT	3	java.lang.String
DATETIME	4	java.sql.Timestamp
USER_DEFINED	5	java.lang.Object

Additionally, a property can also be multi-valued, in which case the value will be a java.util.Collection of objects of the property's type (e.g. java.lang.String's).

This class provides utility methods to get string representations of the type names, to determine a type from a java.sql.Type, and to get the list of comparision operators for a certain type.

Field Summary

static int	BOOLEAN The constant for a boolean type (0).
static java.lang.String	CONTAINS The contains ("contains") comparator constant.
static java.lang.String	CONTAINS_ALL The contains all ("containsall") comparator constant.
static int	DATETIME The constant for a datetime type (4).
static java.lang.String	EQUALS The equals (==) comparator constant.
static int	FLOAT The constant for the floating-point numeric type (2).
static java.lang.String	GREATER_THAN The greater than (>) comparator constant.
static java.lang.String	GREATER_THAN_EQUALS The greater than or equals (>=) comparator constant.
static int	INTEGER The constant for a numeric type (1).
static java.lang.String	LESS_THAN The less than (<) comparator constant.
static java.lang.String	LESS_THAN_EQUALS The less than or equals (<=) comparator constant.
static java.lang.String	LIKE The wildcard pattern ("like") comparator constant.
static int	MULTI_VALUED The constant for a multivalued type (6).
static java.lang.String	NOT_EQUALS The not equals (!=) comparator constant.
static java.lang.String	OR The "or" (||) logical operator.
static int	TEXT The constant for a text type (3).
static int	USER_DEFINED The constant for a user defined type (5).
