readFully
public static byte[] readFully(java.io.File file) throws java.io.IOException
Used as an alternate to Java's nio Files.readAllBytes.This customized version for File is provide (instead of just using
readFully(java.io.InputStream)
with a FileInputStream) because with a File we can determine the total size of the array and do not need to have a buffer. This results in a memory footprint that is half the size ofreadFully(java.io.InputStream)
Code provided from Stackoverflow
- Parameters:
file
- The file from which we should retrieve the bytes from- Returns:
- A byte[] containing all of the file's data
- Throws:
java.io.IOException
- Thrown if there is a problem while reading the file.

readFully
public static byte[] readFully(java.io.InputStream stream) throws java.io.IOException
Provided as a simple way to fully read an InputStream into a byte[].This method will block until the InputStream has been fully read, so if you provide an InputStream that is non-finite, you're gonna have a bad time.
- Parameters:
stream
- The Stream to be read.- Returns:
- A byte[] containing all of the data provided by the InputStream
- Throws:
java.io.IOException
- If the first byte cannot be read for any reason other than the end of the file, if the input stream has been closed, or if some other I/O error occurs.
