Methods

buteBufferToByteString

public static ByteString buteBufferToByteString(ByteBuffer buffer)

Converts a ByteBuffer to a ByteString.

Parameters

buffer – buffer to convert

Returns

ByteString instance with the same contents. Might be coupled to the passed in ByteBuffer and reflect changes on that buffer.

byteBufferToArray

public static byte[] byteBufferToArray(ByteBuffer buffer)

Converts a ByteBuffer instance to a plain byte array. This method respects whether the buffer is read-only or has an underlying array available. In cases where an array is present and can be accessed, this array will be returned. Otherwise a copy is created.

Parameters

buffer – the buffer to convert

Returns

array with contents of the buffer. Should not be modified usually
