Member Function Documentation

check_GE_signature() [1/2]

bool stir::GE::RDF_HDF5::GEHDF5Wrapper::check_GE_signature ( const std::string &  filename )

static

check signature to see if this is a GE RDF9 or higher file

calls current_GE_signature(H5::H5file&)

Referenced by stir::GE::RDF_HDF5::CListModeDataGEHDF5::get_empty_record_sptr().

check_GE_signature() [2/2]

bool stir::GE::RDF_HDF5::GEHDF5Wrapper::check_GE_signature ( H5::H5File &  file )

static

check signature to see if this is a GE RDF9 or higher HDF5 file

does minimal checks to see if expected datasets are present in the HDF5 object

References stir::error().

initialise_proj_data()

Succeeded stir::GE::RDF_HDF5::GEHDF5Wrapper::initialise_proj_data

(

const unsigned int

view_num

)

Initialises data for reading projections. Sets up reading addresses and inspect sizes.

Parameters

view_num

uses 1-based indexing

this function has to be called for each projection/view_num

References stir::error().

initialise_geo_factors_data()

Succeeded stir::GE::RDF_HDF5::GEHDF5Wrapper::initialise_geo_factors_data

(

const unsigned int

slice_num

)

Initialises data for reading geometric normalisation factors. Sets up reading addresses and inspect sizes.

Parameters

slice_num

uses 1-based indexing

References stir::error().

read_singles()

Succeeded stir::GE::RDF_HDF5::GEHDF5Wrapper::read_singles	(	Array< 1, unsigned int > &	output,
		const unsigned int	current_id
	)

read singles at time slice current_id

Parameters

[in]

current_id

is a 1-based index

get_exam_info_sptr()

shared_ptr< ExamInfo > stir::GE::RDF_HDF5::GEHDF5Wrapper::get_exam_info_sptr ( ) const

inline

Get shared pointer to exam info.

Warning

Use with care. If you modify the object in a shared ptr, everything using the same shared pointer will be affected.

get_file()

const H5::H5File & stir::GE::RDF_HDF5::GEHDF5Wrapper::get_file ( ) const

inline
