Buf

trait Buf extends AnyRef

Buf represents a fixed, immutable byte buffer. Buffers may be sliced and concatenated, and thus be used to implement bytestreams.

Note: There is a Java-friendly API for this trait: com.twitter.io.AbstractBuf.

Abstract Value Members

  1. abstract def length: Int

    The number of bytes in the buffer

  2. abstract def slice(from: Int, until: Int): Buf

    Returns a new buffer representing a slice of this buffer, delimited by the indices from inclusive and until exclusive: [from, until).

    Returns a new buffer representing a slice of this buffer, delimited by the indices from inclusive and until exclusive: [from, until). Out of bounds indices are truncated. Negative indices are not accepted.

  3. abstract def unsafeByteArrayBuf: Option[ByteArray]

    Helper to support 0-copy coercion to Buf.

    Helper to support 0-copy coercion to Buf.ByteArray.

  4. abstract def write(output: Array[Byte], off: Int): Unit

    Write the entire contents of the buffer into the given array at the given offset.

    Write the entire contents of the buffer into the given array at the given offset. Partial writes aren't supported directly through this API; they easily performed by first slicing the buffer.

    Annotations
    @throws( classOf[IllegalArgumentException] )
    Exceptions thrown
    IllegalArgumentException

    when output is too small to contain all the data.
