decodeIntoByteArray
Decodes symbols from the specified source array or its subrange and writes resulting bytes into the destination array. Returns the number of bytes written.
The symbols for decoding are not required to be padded.
However, if there is a padding character present, the correct amount of padding character(s) must be present.
The padding character '=' is interpreted as the end of the encoded byte data. Subsequent symbols are prohibited.
Parameters
source - the array to decode symbols from.
destination - the array to write bytes into.
destinationOffset - the starting index in the destination array to write bytes to, 0 by default.
startIndex - the beginning (inclusive) of the subrange to decode, 0 by default.
endIndex - the end (exclusive) of the subrange to decode, size of the source array by default.
Exceptions
IndexOutOfBoundsException - when startIndex or endIndex is out of range of source array indices.
IllegalArgumentException - when startIndex > endIndex.
IndexOutOfBoundsException - when the resulting bytes don't fit into the destination array starting at the specified destinationOffset,
or when that index is out of the destination array indices range.
IllegalArgumentException - when the symbols for decoding are padded incorrectly or there are extra symbols after the padding.
Return the number of bytes written into destination array.
fun decodeIntoByteArray(
source: CharSequence,
destination: ByteArray,
destinationOffset: Int = 0,
startIndex: Int = 0,
endIndex: Int = source.length
): Int(source)
Decodes symbols from the specified source char sequence or its substring and writes resulting bytes into the destination array. Returns the number of bytes written.
The symbols for decoding are not required to be padded.
However, if there is a padding character present, the correct amount of padding character(s) must be present.
The padding character '=' is interpreted as the end of the encoded byte data. Subsequent symbols are prohibited.
Parameters
source - the char sequence to decode symbols from.
destination - the array to write bytes into.
destinationOffset - the starting index in the destination array to write bytes to, 0 by default.
startIndex - the beginning (inclusive) of the substring to decode, 0 by default.
endIndex - the end (exclusive) of the substring to decode, length of the source by default.
Exceptions
IndexOutOfBoundsException - when startIndex or endIndex is out of range of source indices.
IllegalArgumentException - when startIndex > endIndex.
IndexOutOfBoundsException - when the resulting bytes don't fit into the destination array starting at the specified destinationOffset,
or when that index is out of the destination array indices range.
IllegalArgumentException - when the symbols for decoding are padded incorrectly or there are extra symbols after the padding.
Return the number of bytes written into destination array.
