A PCRE internal error occured. This might be caused by a faulty plugin

====== Function INVALID-METHOD-ERROR ====== ====Syntax==== * **invalid-method-error** //method format-control ''&rest'' args// → //[[CL:Glossary:implementation-dependent]]// ====Arguments and Values==== * //method// - a //[[CL:Glossary:method]]//. * //format-control// - a //[[CL:Glossary:format control]]//. * //args// - //[[CL:Glossary:format arguments]]// for the //format-control//. ====Description==== The //[[CL:Glossary:function]]// **invalid-method-error** is used to signal an error of type **[[CL:Types:error]]** when there is an applicable //[[CL:Glossary:method]]// whose //[[CL:Glossary:qualifier|qualifiers]]// are not valid for the method combination type. The error message is constructed by using the //format-control// suitable for **[[CL:Functions:format]]** and any //args// to it. Because an implementation may need to add additional contextual information to the error message, **invalid-method-error** should be called only within the dynamic extent of a method combination function. The //[[CL:Glossary:function]]// **invalid-method-error** is called automatically when a //[[CL:Glossary:method]]// fails to satisfy every //[[CL:Glossary:qualifier]]// pattern and predicate in a **[[CL:Macros:define-method-combination]]** //[[CL:Glossary:form]]//. A method combination function that imposes additional restrictions should call **invalid-method-error** explicitly if it encounters a //[[CL:Glossary:method]]// it cannot accept. Whether **invalid-method-error** returns to its caller or exits via **[[CL:Special Operators:throw]]** is //[[CL:Glossary:implementation-dependent]]//. ====Examples==== None. ====Side Effects==== The debugger might be entered. ====Affected By==== **[[CL:Variables:star-break-on-signals-star|*break-on-signals*]]** ====Exceptional Situations==== None. ====See Also==== **[[CL:Macros:define-method-combination|Macro DEFINE-METHOD-COMBINATION]]** ====Notes==== None. \issue{FORMAT-STRING-ARGUMENTS:SPECIFY}
