### MemoryInputStream

    public MemoryInputStream(FreeableMemory mem)

Method Detail

### read

    public int read()
             throws java.io.IOException

  Specified by:
    `read` in class `java.io.InputStream`
  Throws:
    `java.io.IOException`

### readFully

    public void readFully(byte[] buffer,
                          int offset,
                          int count)
                   throws java.io.IOException

  Description copied from class: `AbstractDataInput`
  Read bytes from this file into `buffer` starting at offset `offset`. This method blocks until `count` number of bytes have been read.

  Specified by:
    `readFully` in interface `java.io.DataInput`
  Overrides:
    `readFully` in class `AbstractDataInput`
  Parameters:
    `buffer` - the buffer to read bytes into.
    `offset` - the initial position in `buffer` to store the bytes read from this file.
    `count` - the maximum number of bytes to store in `buffer`.
  Throws:
    `java.io.EOFException` - if the end of this file is detected.
    `java.io.IOException` - if this file is closed or another I/O error occurs.

### seekInternal

    protected void seekInternal(int pos)

  Specified by:
    `seekInternal` in class `AbstractDataInput`

### getPosition

    protected int getPosition()

  Specified by:
    `getPosition` in class `AbstractDataInput`

### skipBytes

    public int skipBytes(int n)
                  throws java.io.IOException

  Throws:
    `java.io.IOException`

### close

    public void close()

  Specified by:
    `close` in interface `java.io.Closeable`
  Overrides:
    `close` in class `java.io.InputStream`
