Enum Class StandardOperation
- All Implemented Interfaces:
-
Serializable,Comparable<StandardOperation>,Constable,Operation
public enum StandardOperation extends Enum<StandardOperation> implements Operation
Defines the standard dynamic operations. The operations
GET and SET must be used as part of a NamespaceOperation. NamedOperation can then be further used on these NamespaceOperations to bind the name parameter of GET and SET operations, in which case it disappears from their type signature. NamedOperation can also be used to decorate CALL and NEW operations with a diagnostic name, and as such it does not affect their type signature.Nested Class Summary

Enum Constant Details
GET
public static final StandardOperation GET
Get the value from a namespace defined on an object. Call sites with this operation should have a signature of
(receiver, name)→value or (receiver)→value when used with NamedOperation, with all parameters and return type being of any type (either primitive or reference). This operation must always be used as part of a NamespaceOperation.SET
public static final StandardOperation SET
Set the value in a namespace defined on an object. Call sites with this operation should have a signature of
(receiver, name, value)→void or (receiver, value)→void when used with NamedOperation, with all parameters and return type being of any type (either primitive or reference). This operation must always be used as part of a NamespaceOperation.REMOVE
public static final StandardOperation REMOVE
Removes the value from a namespace defined on an object. Call sites with this operation should have a signature of
(receiver, name)→void or (receiver)→void when used with NamedOperation, with all parameters being of any type (either primitive or reference). This operation must always be used as part of a NamespaceOperation.CALL
public static final StandardOperation CALL
Call a callable object. Call sites with this operation should have a signature of
(callable, receiver, arguments...)→value, with all parameters and return type being of any type (either primitive or reference). Typically, the callables are presumed to be methods of an object, so an explicit receiver value is always passed to the callable before the arguments. If a callable has no concept of a receiver, it is free to ignore the value of the receiver argument. The CALL operation is allowed to be used with a NamedOperation even though it does not take a name. Using it with a named operation won't affect its signature; the name is solely meant to be used as a diagnostic description for error messages.NEW
public static final StandardOperation NEW
Call a constructor object. Call sites with this operation should have a signature of
(constructor, arguments...)→value, with all parameters and return type being of any type (either primitive or reference). The NEW operation is allowed to be used with a NamedOperation even though it does not take a name. Using it with a named operation won't affect its signature; the name is solely meant to be used as a diagnostic description for error messages.Method Details
values
public static StandardOperation[] values()
Returns an array containing the constants of this enum class, in the order they are declared.
- Returns:
- an array containing the constants of this enum class, in the order they are declared
valueOf
public static StandardOperation valueOf(String name)
Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name -
NullPointerException- if the argument is null
