Remarks

This class implements a decoder for decoding byte data using the Base64 encoding scheme as specified in RFC 4648 and RFC 2045.

The Base64 padding character '=' is accepted and interpreted as the end of the encoded byte data, but is not required. So if the final unit of the encoded byte data only has two or three Base64 characters (without the corresponding padding character(s) padded), they are decoded as if followed by padding character(s). If there is a padding character present in the final unit, the correct number of padding character(s) must be present, otherwise IllegalArgumentException ( IOException when reading from a Base64 stream) is thrown during decoding.

Instances of Decoder class are safe for use by multiple concurrent threads.

Unless otherwise noted, passing a null argument to a method of this class will cause a java.lang.NullPointerException NullPointerException to be thrown.

If the decoded byte output of the needed size can not be allocated, the decode methods of this class will cause an java.lang.OutOfMemoryError OutOfMemoryError to be thrown.

Methods

Clone()	Creates and returns a copy of this object. (Inherited from Object)
Decode(Byte[], Byte[])	Decodes all bytes from the input byte array using the `Base64` encoding scheme, writing the results into the given output byte array, starting at offset 0.
Decode(Byte[])	Decodes all bytes from the input byte array using the `Base64` encoding scheme, writing the results into a newly-allocated output byte array.
Decode(ByteBuffer)	Decodes all bytes from the input byte buffer using the `Base64` encoding scheme, writing the results into a newly-allocated ByteBuffer.
Decode(String)	Decodes a Base64 encoded String into a newly-allocated byte array using the `Base64` encoding scheme.
Dispose()	(Inherited from Object)
Dispose(Boolean)	(Inherited from Object)
Equals(Object)	Indicates whether some other object is "equal to" this one. (Inherited from Object)
GetHashCode()	Returns a hash code value for the object. (Inherited from Object)
JavaFinalize()	Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object)
Notify()	Wakes up a single thread that is waiting on this object's monitor. (Inherited from Object)
NotifyAll()	Wakes up all threads that are waiting on this object's monitor. (Inherited from Object)
SetHandle(IntPtr, JniHandleOwnership)	Sets the Handle property. (Inherited from Object)
ToArray<T>()	(Inherited from Object)
ToString()	Returns a string representation of the object. (Inherited from Object)
UnregisterFromRuntime()	(Inherited from Object)
Wait()	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>. (Inherited from Object)
Wait(Int64, Int32)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)
Wait(Int64)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)
Wrap(Stream)	Returns an input stream for decoding `Base64` encoded byte stream.
