Detailed Description

Contains the information on the Header of a fragment as described by the original note. The header is a composite entity, build from two parts:

1. The generic part, containing the header type, size and version information;
2. The specific part, containing data that is specific for a particular fragment.

Definition at line 40 of file old/Header.h.

Constructor & Destructor Documentation

Header()

eformat::old::Header::Header	(	const uint32_t *	it,
		uint32_t	match )

To build a header given the containing buffer. I need to know where the header starts in order to do that.

Parameters

it	The exact position where this header should start.
match	The word that this header should match.

Definition at line 21 of file Header24.cxx.

  : m_start(it)
{
  //get endiannesso
  uint32_t m = marker();
  if (m != match) throw EFORMAT_WRONG_MARKER(m, match);
}

Member Function Documentation

check()

bool eformat::old::Header::check ( ) const

virtual

Says if the generic part of the header is valid. This may throw exceptions.

Reimplemented in eformat::old::FullEventFragment, eformat::old::ROBFragment, eformat::old::ROSFragment, and eformat::old::SubDetectorFragment.

Definition at line 29 of file Header24.cxx.

{
  if ( version() >> 16 != eformat::MAJOR_OLD_VERSION )
    throw EFORMAT_BAD_VERSION(version() >> 16, eformat::MAJOR_OLD_VERSION);
  if ( header_size_word() != (9 + nstatus() + noffset() + nspecific()) )
    throw EFORMAT_SIZE_CHECK(header_size_word(),
                 (9 + nstatus() + noffset() + nspecific()));
  return true;
}

Referenced by eformat::old::FullEventFragment::check(), eformat::old::ROBFragment::check(), eformat::old::ROSFragment::check(), and eformat::old::SubDetectorFragment::check().

child()

const uint32_t * eformat::old::Header::child

(

size_t

n

)

const

Returns the nth child fragment. If the nth fragment doesn't exist, an exception is thrown.

Parameters

n	The fragment position, starting at zero, of the child fragment you would like to get.

Definition at line 39 of file Header24.cxx.

{
  if (n >= noffset()) throw EFORMAT_NO_SUCH_CHILD(n, noffset());
  return &m_start[0xffffff & offset()[n]];

fragment_size_word()

uint32_t eformat::old::Header::fragment_size_word ( ) const

inline

Returns the size, in words, of the current fragment.

Definition at line 72 of file old/Header.h.

{ return m_start[1]; }

header_size_word()

uint32_t eformat::old::Header::header_size_word ( ) const

marker()

uint32_t eformat::old::Header::marker ( ) const

inline

Returns the fragment type.

noffset()

uint32_t eformat::old::Header::noffset ( ) const

inline

Returns the number of offset words available. This will also determine the number of child fragments available to this super-fragment.

Definition at line 110 of file old/Header.h.

nstatus()

uint32_t eformat::old::Header::nstatus ( ) const

inline

Returns the number of status words available

Definition at line 98 of file old/Header.h.

offset()

const uint32_t * eformat::old::Header::offset ( void ) const

inline

Returns the offset words, as an iterator to the offset words available.

Definition at line 116 of file old/Header.h.

      { return &m_start[8 + nstatus()]; }

run_no()

uint32_t eformat::old::Header::run_no ( ) const

inline

Returns the current run number.

source_id()

uint32_t eformat::old::Header::source_id ( ) const

inline

specific_header()

const uint32_t * eformat::old::Header::specific_header ( void ) const
