## org.apache.poi.util
Class IOUtils

    java.lang.Object
      org.apache.poi.util.IOUtils

    public final class IOUtils

extends java.lang.Object

Method Summary
`static void` | `copy(java.io.InputStream inp, java.io.OutputStream out)` Copies all the data from the given InputStream to the OutputStream.
`static int` | `readFully(java.io.InputStream in, byte[] b)` Helper method, just calls `readFully(in, b, 0, b.length)`
`static int` | `readFully(java.io.InputStream in, byte[] b, int off, int len)` Same as the normal `in.read(b, off, len)`, but tries to ensure that the entire len number of bytes is read.
`static byte[]` | `toByteArray(java.io.InputStream stream)` Reads all the data from the input stream, and returns the bytes read.

Method Detail

### toByteArray

    public static byte[] toByteArray(java.io.InputStream stream)
                              throws java.io.IOException

  Reads all the data from the input stream, and returns the bytes read.

  Throws:
    `java.io.IOException`

### readFully

    public static int readFully(java.io.InputStream in,
                                byte[] b)
                         throws java.io.IOException

  Helper method, just calls `readFully(in, b, 0, b.length)`

  Throws:
    `java.io.IOException`

### readFully

    public static int readFully(java.io.InputStream in,
                                byte[] b,
                                int off,
                                int len)
                         throws java.io.IOException

  Same as the normal `in.read(b, off, len)`, but tries to ensure that the entire len number of bytes is read.

  If the end of file is reached before any bytes are read, returns -1. If the end of the file is reached after some bytes are read, returns the number of bytes read. If the end of the file isn't reached before len bytes have been read, will return len bytes.

  Throws:
    `java.io.IOException`

### copy

    public static void copy(java.io.InputStream inp,
                            java.io.OutputStream out)
                     throws java.io.IOException

  Copies all the data from the given InputStream to the OutputStream. It leaves both streams open, so you will still need to close them once done.

  Throws:
    `java.io.IOException`
