CheckedOutputStream

public class CheckedOutputStream
extends FilterOutputStream

java.lang.Object
↳	java.io.OutputStream
	↳	java.io.FilterOutputStream
		↳	java.util.zip.CheckedOutputStream

An output stream that also maintains a checksum of the data being written. The checksum can then be used to verify the integrity of the output data.

Summary

From class java.io.FilterOutputStream


    protected
    
    
    OutputStream

out

The underlying output stream to be filtered.

Public constructors
`CheckedOutputStream(OutputStream out, Checksum cksum)` Creates an output stream with the specified Checksum.

Public methods
`Checksum`	`getChecksum()` Returns the Checksum for this output stream.
`void`	`write(byte[] b, int off, int len)` Writes an array of bytes.
`void`	`write(int b)` Writes a byte.

From class


        
          java.io.FilterOutputStream

`void`	`close()` Closes this output stream and releases any system resources associated with the stream.
`void`	`flush()` Flushes this output stream and forces any buffered output bytes to be written out to the stream.
`void`	`write(byte[] b)` Writes `b.length` bytes to this output stream.
`void`	`write(byte[] b, int off, int len)` Writes `len` bytes from the specified `byte` array starting at offset `off` to this output stream.
`void`	`write(int b)` Writes the specified `byte` to this output stream.

From class


        
          java.io.OutputStream

`void`	`close()` Closes this output stream and releases any system resources associated with this stream.
`void`	`flush()` Flushes this output stream and forces any buffered output bytes to be written out.
`static OutputStream`	`nullOutputStream()` Returns a new `OutputStream` which discards all bytes.
`void`	`write(byte[] b)` Writes `b.length` bytes from the specified byte array to this output stream.
`void`	`write(byte[] b, int off, int len)` Writes `len` bytes from the specified byte array starting at offset `off` to this output stream.
`abstract void`	`write(int b)` Writes the specified byte to this output stream.

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
