CLHS: Function METHOD-COMBINATION-ERROR

#

Function METHOD-COMBINATION-ERROR

Syntax:

method-combination-error format-control `&rest` args => implementation-dependent

Arguments and Values:

format-control---a format control.

args---format arguments for format-control.

Description:

The function method-combination-error is used to signal an error in method combination.

The error message is constructed by using a format-control suitable for format and any args to it. Because an implementation may need to add additional contextual information to the error message, method-combination-error should be called only within the dynamic extent of a method combination function.

Whether method-combination-error returns to its caller or exits via throw is implementation-dependent.

Examples: None.
