	BufferedInputStream is an InputStream::Ptr<ELEMENT_TYPE> which provides buffered access. This is useful if calls to the underling stream source can be expensive. This class loads chunks of the stream into memory, and reduces calls to the underlying stream.

	)

BufferedInputStream is an InputStream::Ptr<ELEMENT_TYPE> which provides buffered access. This is useful if calls to the underling stream source can be expensive. This class loads chunks of the stream into memory, and reduces calls to the underlying stream.

Note

if seekable true, the resulting stream is seekable. If seekable is false, the resulting stream is not seekable. If seekable is unspecified (nullopt), the resulting stream is seekable iff the source stream is seekable.

Specifying true (seekable) when the source stream is not seekable is allowed, but requires enuf memory to buffer the ENTIRE contents of the stream (other cases just buffer a bit so require more modest amounts of memory).

Note

See Also StreamReader, as for consumers, this will often work the same as BufferedInputStream, but be somewhat more performant.

Example Usage

InputStream::Ptr<byte> in = BufferedInputStream::New<byte> (fromStream);

Example Usage

CallExpectingBinaryInputStreamPtr (BufferedInputStream::New<byte> (fromStream))
