Method Detail

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

buteBufferToByteString

public static com.google.protobuf.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.
