Method Detail

values

public static AttributeType[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
for (AttributeType c : AttributeType.values())
    System.out.println(c);

Returns:
an array containing the constants of this enum type, in the order they are declared

valueOf

public static AttributeType valueOf(String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:
name - the name of the enum constant to be returned.
Returns:
the enum constant with the specified name
Throws:
IllegalArgumentException - if this enum type has no constant with the specified name
NullPointerException - if the argument is null

typeFor

public static AttributeType typeFor(String name,
                                    Object value)
                             throws SearchException
Get the appropriate @{link AttributeType enum for the given object value.

Parameters:
name - the attribute name (only meaningful to message if exception thrown)
value - the value to lookup the type for
Returns:
the attribute type for this value
Throws:
SearchException - if the given value is not valid for a search attribute

typeFor

public static AttributeType typeFor(Class<?> c)
Get the appropriate @{link AttributeType enum for the given Java Class

Parameters:
c -
Returns:
the attribute type for this value

isSupportedType

public static boolean isSupportedType(Object value)
Test the given value to see if it is a legal type

Parameters:
value -
Returns:
true if the given value is valid as a search attribute

validateValue

public abstract void validateValue(String name,
                                   Object value)
                            throws SearchException
Validate that the given value is in fact of the correct type

Parameters:
name - the attribute name (only meaningful to message if exception thrown)
value - the value to validate against this type
Throws:
SearchException - if the given value is not a valid instance of this type

isComparable

public boolean isComparable()
Is this type comparable?

Returns:
true if this type is comparable

getSupportedJavaTypes

public static Set<Class<?>> getSupportedJavaTypes()
Returns:
all supported built-in types
