Enum Constant Summary

Enum Constants

Enum Constant	Description
ANY	The value may be of any type.
BOOLEAN	The value must be a boolean, i.e.
CONST	The value is a constant, such as 3 or [1,2].
FLOATING_POINT	The value must be a floating-point (64 bit) number (
INTEGER	The value must be a (signed, 64 bit) integer.
LIST	The value must be a list of items, such as a list of strings.
MAP	The value must be a mapping from strings to items.
NULL	The value must be absent, which is usually indicated by null or undefined etc.
RECORD	The value must be a mapping from a fixed, predefined set of keys to a certain value.
STRING	The value must be a sequence of character, i.e.
TUPLE	The value must be a tuple of individual values, i.e.
UNION	The value must be one of a given set of other EValueTypes.
VOID	The value must be absent, which is usually indicated by null or undefined etc.

Enum Constant Detail

ANY

public static final EValueType ANY

The value may be of any type.

BOOLEAN

public static final EValueType BOOLEAN

The value must be a boolean, i.e. true of false.

CONST

public static final EValueType CONST

The value is a constant, such as 3 or [1,2]. This is stronger than e.g. just INTEGER, which allows any integer.

FLOATING_POINT

public static final EValueType FLOATING_POINT

The value must be a floating-point (64 bit) number (

INTEGER

public static final EValueType INTEGER

The value must be a (signed, 64 bit) integer.

LIST

public static final EValueType LIST

The value must be a list of items, such as a list of strings. The type of the items should be one of the available EValueTypes. This value type allows list of arbitrary length, but requires each item to conform to a certain value type.

See Also:

TUPLE

MAP

public static final EValueType MAP

The value must be a mapping from strings to items. That is, the map key must always be of type STRING. The type of the values should be one of the available EValueTypes. This value type allows maps of arbitrary size, but required each value to conform to a certain value type.

See Also:

RECORD

NULL

public static final EValueType NULL

The value must be absent, which is usually indicated by null or undefined etc.

RECORD

public static final EValueType RECORD

The value must be a mapping from a fixed, predefined set of keys to a certain value. The type of each value may be different for each key. Each key may be marked as optional, in which case no mapping must exist for that key.

See Also:

MAP

STRING

public static final EValueType STRING

The value must be a sequence of character, i.e. a string.

TUPLE

public static final EValueType TUPLE

The value must be a tuple of individual values, i.e. a list of fixed size where each item may have a different value type.

See Also:

LIST

UNION

public static final EValueType UNION

The value must be one of a given set of other EValueTypes. For example, a value of type UNION(STRING | INTEGER) must be either be of type STRING or INTEGER.

VOID

public static final EValueType VOID

The value must be absent, which is usually indicated by null or undefined etc.

Method Detail

values

public static EValueType[] 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 (EValueType c : EValueType.values())
    System.out.println(c);

Returns:

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

valueOf

public static EValueType 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

getDisplayName

public String getDisplayName(Locale locale)

Specified by:

getDisplayName in interface INamedUiElement

Returns:

Wert, der das entsprechende Objekt an Oberfläche repräsentiert (wird i.A. zur Laufzeit ermittelt).

getTechnicalName

public String getTechnicalName()

Returns:

The technical (non human-friendly or localized) name of this value type.
