BloombergLP::baljsn::Decoder::decodeAny

Synopses

Declared in <baljsn_decoder.h>

Decode into the specified value without instantiating templates at compile time. Return 0 on success, and a non-zero value otherwise.

int
decodeAny(
    std::istream& stream,
    bdlar::AnyRef* value,
    DecoderOptions const& options);

int
decodeAny(
    std::streambuf* streamBuf,
    bdlar::AnyRef* value,
    DecoderOptions const& options);

Decode into the specified value, of a (template parameter) TYPE, the JSON data read from the specified stream and using the specified options. TYPE shall be a bdlat-compatible sequence, choice, or array type, or a bdlat-compatible dynamic type referring to one of those types. Specifying a nullptr options is equivalent to passing a default-constructed DecoderOptions in options. Return 0 on success, and a non-zero value otherwise. 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 baljsn package documentation for more details.

template<class TYPE>
int
decodeAny(
    std::istream& stream,
    TYPE* value,
    DecoderOptions const& options);

Same as the preceding overload, accepting a nullable options pointer.

template<class TYPE>
int
decodeAny(
    std::istream& stream,
    TYPE* value,
    DecoderOptions const* options = 0);
