Base64Encoder

protected Base64Encoder(Base64Variant v,
                        byte[] values,

Method Detail

isCompleted

public boolean isCompleted()

Description copied from class: AsciiValueEncoder

Method that can alternatively be called to determine whether encoder has encoded all data it has. Generally called right after a call to AsciiValueEncoder.encodeMore(char[], int, int), to figure out whether buffer flush is needed (there is more data), or encoding is complete.

Specified by:

isCompleted in class AsciiValueEncoder

encodeMore

public int encodeMore(char[] buffer,
                      int outPtr,
                      int outEnd)

Specified by:

encodeMore in class AsciiValueEncoder

Returns:

Value of pointer after all remaining data (which may be "none") that can be encoded (as constrained by buffer length) has been encoded. Has to exceed 'ptr' value sent in; will be equal to it if nothing was encoded (which should only occur when everything has been encoded, as long as AsciiValueEncoder.bufferNeedsFlush(int) is appropriately called once before calling this method)

encodeMore

public int encodeMore(byte[] buffer,
                      int outPtr,
                      int outEnd)

Specified by:

encodeMore in class AsciiValueEncoder

Returns:

Value of pointer after all remaining data (which may be "none") that can be encoded (as constrained by buffer length) has been encoded. Has to exceed 'ptr' value sent in; will be equal to it if nothing was encoded (which should only occur when everything has been encoded, as long as AsciiValueEncoder.bufferNeedsFlush(int) is appropriately called once before calling this method)
