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 theseNamespaceOperations 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 public static final [StandardOperation](StandardOperation.html "enum in jdk.dynalink") 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](NamedOperation.html "class in jdk.dynalink"), 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](NamespaceOperation.html "class in jdk.dynalink"). * #### SET public static final [StandardOperation](StandardOperation.html "enum in jdk.dynalink") 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](NamedOperation.html "class in jdk.dynalink"), 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](NamespaceOperation.html "class in jdk.dynalink"). * #### REMOVE public static final [StandardOperation](StandardOperation.html "enum in jdk.dynalink") 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](NamedOperation.html "class in jdk.dynalink"), with all parameters being of any type (either primitive or reference). This operation must always be used as part of a [NamespaceOperation](NamespaceOperation.html "class in jdk.dynalink"). * #### CALL public static final [StandardOperation](StandardOperation.html "enum in jdk.dynalink") 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](NamedOperation.html "class in jdk.dynalink") 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](StandardOperation.html "enum in jdk.dynalink") 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](NamedOperation.html "class in jdk.dynalink") 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 Detail
* #### values public static [StandardOperation](StandardOperation.html "enum in jdk.dynalink")[] 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 (StandardOperation c : StandardOperation.values()) System.out.println(c); Returns: an array containing the constants of this enum type, in the order they are declared * #### valueOf public static [StandardOperation](StandardOperation.html "enum in jdk.dynalink") valueOf([String](../../../java.base/java/lang/String.html "class in java.lang") 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](../../../java.base/java/lang/IllegalArgumentException.html "class in java.lang")` \- if this enum type has no constant with the specified name `[NullPointerException](../../../java.base/java/lang/NullPointerException.html "class in java.lang")` \- if the argument is null
