[call [arg [vset CMD]] [method "info [vset MODIFIER] method"] [arg option] [arg methodName]] This introspection [term "submethod"] provides access to the details of [arg methodName] provided by [arg [vset CMD]]. Permitted values for [arg option] are: [list_begin itemized] [item] [const args] returns a list containing the parameter names of [arg methodName], in order of the method-parameter specification. [item] [const body] returns the body script of [arg methodName]. [item] [const definition] returns a canonical command list which allows for (re-)define [arg methodName]. [item] [const definitionhandle] returns the [term "method handle"] for a [term "submethod"] in a [term "method ensemble"] from the perspective of [arg [vset CMD]] as method provider. [arg methodName] must contain a complete [term "method path"]. [item] [const exists] returns 1 if there is a [arg methodName] provided by [arg [vset CMD]], returns 0 otherwise. [item] [const handle] returns the [term "method handle"] for [arg methodName]. [item] [const origin] returns the aliased command if [arg methodName] is an [term "alias method"], or an empty string otherwise. [item] [const parameters] returns the [term "parameter specification"] of [arg methodName] as a list of parameter names and type specifications. [item] [const registrationhandle] returns the [term "method handle"] for a [term "submethod"] in a [term "method ensemble"] from the perspective of the method caller. [arg methodName] must contain a complete [term "method path"]. [item] [const returns] gives the [term "type specification"] defined for the return value of [arg methodName]. [item] [const submethods] returns the names of all [term "submethod"]s of [arg methodName], if [arg methodName] is a [term "method ensemble"]. Otherwise, an empty string is returned. [item] [const syntax] returns the method parameters of [arg methodName] as a concrete-syntax description to be used in human-understandable messages (e.g., errors or warnings, documentation strings). [item] [const type] returns whether [arg methodName] is a [emph scripted] method, an [emph alias] method, a [emph forwarder] method, or a [emph setter] method.

Methods covered include those defined using , [const [vset SCOPE]] [method alias], and [const [vset SCOPE]] [method forward]. The returned methods can be limited to those whose names match [arg namePattern] (see [cmd "string match"]). [para] By setting [option -callprotection], only methods of a certain [term "call protection"] [arg level] ([term "public"], [term "protected"], or [term "private"]) will be returned.

By turning on the [term switch] [option -guards], the corresponding guard expressions, if any, are also reported along with each mixin as a three-element list: [arg className] -guard [arg guardExpr]. The returned [term "mixin class"]es can be limited to those whose names match [arg patterns] (see [cmd "string match"]). [call [arg [vset CMD]] [method "info [vset MODIFIER] slots"] [opt "[option -type] [arg className]"] [arg pattern]] If [arg pattern] is not specified, returns the object names of all [term "slot object"]s defined by [arg [vset CMD]]. The returned [term "slot object"]s can be limited according to any or a combination of the following criteria: First, [term "slot object"]s can be filtered based on their command names matching [arg namePattern] (see [cmd "string match"]). Second, [option "-type"] allows to select [term "slot object"]s which are instantiated from a subclass [arg className] of [cmd nx::Slot] (default: [cmd nx::Slot]). [call [arg [vset CMD]] [method "info [vset MODIFIER] variables"] [arg pattern]] If [arg pattern] is omitted, returns the object names of all [term "slot object"]s provided by [arg [vset CMD]] which are responsible for managing properties and variables of [arg [vset CMD]]. Otherwise, only [term "slot object"]s whose names match [arg pattern] are returned. [para] This is equivalent to calling: [arg [vset CMD]] [method "info [vset MODIFIER] slots"] -type ::nx::VariableSlot [opt [arg namePattern]]. [para] To extract details of each [term "slot object"], use the [method info] submethods available for each [term "slot object"].
