Types

phase()

@type phase() :: :command | :data | :complete

t()

@type t() :: %Dimse.Message.Assembler{
  command: map() | nil,
  command_buffer: iodata(),
  context_id: pos_integer() | nil,
  data_buffer: iodata(),
  phase: phase()
}

Functions

feed(asm, pdv)

@spec feed(t(), Dimse.Pdu.PresentationDataValue.t()) ::
  {:continue, t()} | {:complete, Dimse.Message.t()} | {:error, term()}

Returns:

{:continue, assembler} — more fragments needed
{:complete, message} — message fully assembled
{:error, reason} — protocol error

new()
