encodeToAppendable
fun <A : Appendable> Base64.encodeToAppendable(source: ByteString, destination: A, startIndex: Int = 0, endIndex: Int = source.size): A(source)
Encodes bytes from the specified source byte string or its subrange and appends resulting symbols to the destination appendable. Returns the destination appendable.
If the size of the source byte string or its subrange is not an integral multiple of 3, the result is padded with '=' to an integral multiple of 4 symbols.
Return
the destination appendable.
Parameters
source
the byte string to encode bytes from.
destination
the appendable to append symbols to.
startIndex
the beginning (inclusive) of the subrange to encode, 0 by default.
endIndex
the end (exclusive) of the subrange to encode, size of the source byte string by default.
Throws
when startIndex or endIndex is out of range of source byte string indices.
when startIndex > endIndex.
