Member Function Documentation

readComponent() [1/2]

template<typename T>

std::shared_ptr< T > lsst::afw::image::ExposureFitsReader::ArchiveReader::readComponent ( afw::fits::Fits * fitsFile, Component c )

inline

Read a known component, if available.

Parameters

fitsFile	The file from which to read the component. Must match the metadata used to construct this object.
c	The component to read. Must be convertible to T.

Returns

The desired component, or nullptr if the file could not be read.

Definition at line 293 of file ExposureFitsReader.cc.

readComponent() [2/2]

template<typename T>

std::shared_ptr< T > lsst::afw::image::ExposureFitsReader::ArchiveReader::readComponent ( afw::fits::Fits * fitsFile, std::string c )

inline

Read an arbitrary component, if available.

Parameters

fitsFile	The file from which to read the component. Must match the metadata used to construct this object.
c	The archive ID of the component to read.

Returns

The desired component, or nullptr if the file could not be read.

Exceptions

pex::exceptions::NotFoundError

Thrown if the component is registered in the file metadata but could not be found.

Note

When accessing from python, components with derived subclasses, such as TransmissionCurve, are not properly type converted and thus the specialized reader must be used instead of readComponent.

readExtraComponents()

std::map< std::string, std::shared_ptr< table::io::Persistable > > lsst::afw::image::ExposureFitsReader::ArchiveReader::readExtraComponents ( afw::fits::Fits * fitsFile )

inline

Read the components that are stored using arbitrary-component support.

Parameters

fitsFile

The file from which to read the components. Must match the metadata used to construct this object.

Returns

a map from string IDs to components, or an empty map if the file could not be read.
