:mrdocs:

Decode into a type‐erased `bdlar::AnyRef` from the specified `buffer`.

== Synopsis

Declared in `<balxml_decoder.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<class TYPE>
int
decodeAny(
    std::streambuf* buffer,
    TYPE* object,
    char const* uri = 0);
----

== Description

Decode `object` from `buffer` without instantiating templates.

Decode the specified `object` of parameterized `TYPE` from the specified stream `buffer`. The (optionally) specified `uri` is used for identifying the input document in error messages. Return 0 on success, and a non‐zero value otherwise. A compilation error will result unless `TYPE` conforms to the requirements of a `bdlat` sequence or choice, as described in `bdlat_sequencefunctions` and `bdlat_choicefunctions`. Note that this function behaves identically to `decode`, but does not instantiate any templates at compile time at the expense of being slightly slower at runtime; see the `balxml` package documentation for more details.

== Return Value

0 on success, and a non‐zero value otherwise
