[in]fileNameName of the file to read.
[in]hduHDU to read, where 0 is the primary. The special value of afw::fits::DEFAULT_HDU skips the primary HDU if it is empty.

◆ toString()

std::string lsst::afw::math::TransformBoundedField::toString ( ) const
overrideprivatevirtual

Implements lsst::afw::math::BoundedField.

Definition at line 156 of file TransformBoundedField.cc.

156{ return "TransformBoundedField"; }

◆ write()

void lsst::afw::math::TransformBoundedField::write ( OutputArchiveHandle & handle) const
overrideprotectedvirtual

Write the object to one or more catalogs.

The handle object passed to this function provides an interface for adding new catalogs and adding nested objects to the same archive (while checking for duplicates). See OutputArchiveHandle for more information.

Reimplemented from lsst::afw::table::io::Persistable.

136 record->set(keys.bbox, getBBox());
137 record->set(keys.frameSet, formatters::stringToBytes(getTransform().writeString()));
138 handle.saveCatalog(catalog);
139}
ndarray::Array< std::uint8_t, 1, 1 > stringToBytes(std::string const &str)

◆ writeFits() [1/3]

void lsst::afw::table::io::Persistable::writeFits ( fits::Fits & fitsfile) const
inherited

Write the object to an already-open FITS object.

Parameters
[in]fitsfileOpen FITS object to write to.

Definition at line 18 of file Persistable.cc.

18 {
19 OutputArchive archive;
20 archive.put(this);
21 archive.writeFits(fitsfile);
22}

◆ writeFits() [2/3]

void lsst::afw::table::io::Persistable::writeFits ( fits::MemFileManager & manager,
std::string const & mode = "w" ) const
inherited

Write the object to a FITS image in memory.

Parameters
[in]managerName of the file to write to.
[in]modeIf "w", any existing file with the given name will be overwritten. If "a", new HDUs will be appended to an existing file.

Definition at line 29 of file Persistable.cc.

29 {
30 fits::Fits fitsfile(manager, mode, fits::Fits::AUTO_CLOSE | fits::Fits::AUTO_CHECK);
31 writeFits(fitsfile);
32}
void writeFits(std::string const &fileName, std::string const &mode="w") const
Write the object to a regular FITS file.

◆ writeFits() [3/3]

void lsst::afw::table::io::Persistable::writeFits ( std::string const & fileName,
std::string const & mode = "w" ) const
inherited

Write the object to a regular FITS file.

Parameters
[in]fileNameName of the file to write to.
[in]modeIf "w", any existing file with the given name will be overwritten. If "a", new HDUs will be appended to an existing file.

Definition at line 24 of file Persistable.cc.
