Invoking a stream reading method without verifying the number of bytes read can lead to erroneous assumptions. A Stream can represent any I/O
operation, such as reading a file, network communication, or inter-process communication. As such, it is not guaranteed that the byte[]
passed into the method will be filled with the requested number of bytes. Therefore, inspecting the value returned by the reading method is important
to ensure the number of bytes read.
Neglecting the returned length read can result in a bug that is difficult to reproduce.
This rule raises an issue when the returned value is ignored for the following methods:
