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
NamespaceOperation
s 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.-

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 withNamedOperation
, with all parameters and return type being of any type (either primitive or reference). This operation must always be used as part of aNamespaceOperation
. -
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 withNamedOperation
, with all parameters and return type being of any type (either primitive or reference). This operation must always be used as part of aNamespaceOperation
. -
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 withNamedOperation
, with all parameters being of any type (either primitive or reference). This operation must always be used as part of aNamespaceOperation
. -
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. TheCALL
operation is allowed to be used with aNamedOperation
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
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). TheNEW
operation is allowed to be used with aNamedOperation
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.

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

name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException
