OpenJDK 27 · jdk.dynalink.StandardOperation · APIdia, the JavaDoc alternative

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.

CALL back to summary

CALL	back to summary
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.

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.

GET	back to summary
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`.

NEW back to summary

NEW	back to summary
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.

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.

REMOVE back to summary

REMOVE	back to summary
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`. Since 10

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.

Since: 10

SET back to summary

SET	back to summary
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`.

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.
