BloombergLP::bslx::InStreamFunctions::bdexStreamInImp

Synopsis

Declared in <bslx_instreamfunctions.h>

template<
    class STREAM,
    class VALUE_TYPE>
STREAM&
bdexStreamInImp(
    STREAM& stream,
    VALUE_TYPE& variable,
    int version,
    IsNotEnumType const& category);

Description

Assign to the specified variable the VALUE_TYPE value read from the specified input stream using the specified version format, and return a reference to stream. If stream is initially invalid, this operation has no effect. If version is not supported by VALUE_TYPE, variable is unaltered and stream is invalidated, but otherwise unmodified. If version is supported but stream becomes invalid during this operation, variable has an undefined, but valid, state. Note that this function is for internal use only. See the bslx package-level documentation for more information on BDEX streaming of value-semantic types and containers.

Return Value

a reference to stream

Parameters

Name	Description
stream	input stream from which to read
