- Serializable,- Comparable<StandardOperation>,- Operation
 
 public enum StandardOperation extends Enum<StandardOperation> implements Operation Defines the standard dynamic operations. The operationsGETandSETmust be used as part of aNamespaceOperation.NamedOperationcan then be further used on theseNamespaceOperations to bind the name parameter ofGETandSEToperations, in which case it disappears from their type signature.NamedOperationcan also be used to decorateCALLandNEWoperations with a diagnostic name, and as such it does not affect their type signature.

Enum Constant Detail- 
GETpublic 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)→valueor(receiver)→valuewhen 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.
 - 
SETpublic 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)→voidor(receiver, value)→voidwhen 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.
 - 
REMOVEpublic 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)→voidor(receiver)→voidwhen used withNamedOperation, with all parameters being of any type (either primitive or reference). This operation must always be used as part of aNamespaceOperation.
 - 
CALLpublic 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. TheCALLoperation is allowed to be used with aNamedOperationeven 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.
 - 
NEWpublic 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). TheNEWoperation is allowed to be used with aNamedOperationeven 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- 
valuespublic static StandardOperation[] 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
 
 - 
valueOfpublic static StandardOperation 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
