====Buffer:getParent====
{{luaself|:getParent|args=value|args2=functionName, ...}}
{{hatnote|Note that there is no 'getChild' method<ref group='note' name='in-dependents'/>}}

Returns parent Buffer, or, if none exists, creates a new Buffer and returns it as the adopted parent. As with {{luaself|:_in}}, this does not automatically append the adoptive child to the new parent.

Pass a non-false <code>value</code> and this performs an op on the parent object.

If passed anything other than ''value'' (including nil), this requires that ''value'' names a function available to the parent object, which this calls and forwards the additional {{luaself|varargs|plain=yes}}.

Pass only a table ''value'' which has no metatable and this forwards ''value'' to the parent which calls {{luaself|:_all|args=value}}.

Given only a string starting with {{code|_}} and naming a parent function, this calls it on the parent without arguments. Any other [[#valid|valid]] singular argument [[#Buffer:|appends]] to the end of the parent Buffer.<ref group="note">In other words, {{luaself|:getParent|args='_nil'}} is shorthand for {{luaself|:getParent|args=():_nil()}}, however, {{luaself|:getParent|args='match'}} simply appends "match" to the parent. Note that you may still call {{luaself|Buffer|library|***:match|args=pattern}} on a parent via {{luaself|:getParent|args='match', pattern}}.</ref>
