C++ equivalent of Java ByteBuffer?

I'm looking for a C++ "equivalent" of Java ByteBuffer.

I'm probably missing the obvious or just need an isolated usage example to clarify. I've looked through the iostream family & it looks like it may provide a basis. Specifically, I want to be able to:

• build a buffer from a byte array/point and get primitives from the buffer, e.g. getByte, getInt
• build a buffer using primitives e.g. putByte, putInt and then get the byte array/pointer.
