Member Function Documentation

GetLengthImpl()

int64_t Aws::Crt::Io::StdIOStreamInputStream::GetLengthImpl ( ) const

overrideprotectedvirtualnoexcept

Returns

the total length of the available data for the stream.

-1 if not available.

Implements Aws::Crt::Io::InputStream.

GetStatusImpl()

StreamStatus Aws::Crt::Io::StdIOStreamInputStream::GetStatusImpl ( ) const

overrideprotectedvirtualnoexcept

Returns

the current status of the stream.

Implements Aws::Crt::Io::InputStream.

IsValid()

bool Aws::Crt::Io::StdIOStreamInputStream::IsValid ( ) const

overridevirtualnoexcept

Returns

true/false if this object is in a valid state

Implements Aws::Crt::Io::InputStream.

PeekImpl()

int64_t Aws::Crt::Io::StdIOStreamInputStream::PeekImpl ( ) const

overrideprotectedvirtualnoexcept

Peeks the stream

Essentially calls peek on the underlying istream

Returns

return value of the underlying istream::peek

Implements Aws::Crt::Io::InputStream.
