wrapByteBuffer

open static fun wrapByteBuffer(byteBuffer: ByteBuffer!): Bytes! (source)

Wrap a full Java NIO ByteBuffer as a Bytes value.

Note that any change to the content of the byteBuf may be reflected in the returned value.

Parameters

byteBuffer - ByteBuffer!: The ByteBuffer to wrap.

Return
Bytes!: A Bytes value.

open static fun wrapByteBuffer(byteBuffer: ByteBuffer!, offset: Int, size: Int): Bytes! (source)

Wrap a slice of a Java NIO ByteBuf as a Bytes value.

Note that any change to the content of the buffer may be reflected in the returned value.

Parameters

byteBuffer - ByteBuffer!: The ByteBuffer to wrap.

offset - Int: The offset in byteBuffer from which to expose the bytes in the returned value. That is, wrapByteBuffer(byteBuffer, i, 1).get(0) == byteBuffer.getByte(i).

size - Int: The size of the returned value.

Exceptions

IndexOutOfBoundsException - if offset < 0 || (byteBuffer.limit() > 0 && offset >= byteBuf.limit()).

IllegalArgumentException - if length < 0 || offset + length > byteBuffer.limit().

Return
Bytes!: A Bytes value.
