Detailed Description

Table class that must contain a unique ID field and a celestial coordinate field.

SimpleTable / SimpleRecord are intended to be the base class for records representing astronomical objects. In additional to the minimal schema and the convenience accessors it allows, a SimpleTable may hold an IdFactory object that is used to assign unique IDs to new records.

Default-construct an associated record (protected implementation).

Reimplemented from lsst::afw::table::BaseTable.

Reimplemented in lsst::afw::table::SourceTable.

Definition at line 112 of file Simple.cc.

                                                    {
     auto record = constructRecord<SimpleRecord>();
     if (getIdFactory()) record->setId((*getIdFactory())());
     return record;
 }

◆ checkSchema()

static bool lsst::afw::table::SimpleTable::checkSchema ( Schema const & other )

inlinestatic

Return true if the given schema is a valid SimpleTable schema.

This will always be true if the given schema was originally constructed using makeMinimalSchema(), and will rarely be true otherwise.

Definition at line 152 of file Simple.h.

152 { return other.contains(getMinimalSchema().schema); }

◆ clone()

std::shared_ptr<SimpleTable> lsst::afw::table::SimpleTable::clone ( ) const

inline

Return a polymorphic deep copy of the table.

Derived classes should reimplement by static-casting the output of _clone to a pointer-to-derived to simulate covariant return types.

Cloning a table does not clone its associated records; the new table produced by clone() does not have any associated records.

Definition at line 176 of file Simple.h.

176 { return std::static_pointer_cast<SimpleTable>(_clone()); }

lsst::afw::table::SimpleTable::_clone

std::shared_ptr< BaseTable > _clone() const override

Clone implementation with noncovariant return types.

Definition: Simple.cc:108

◆ constructRecord()

template<typename RecordT , typename ... Args>

std::shared_ptr< RecordT > lsst::afw::table::BaseTable::constructRecord ( Args &&... args )

protectedinherited

Helper function that must be used by all _makeRecord overrides to actually construct records.

Use of this function is enforced by the fact that Record::ConstructionToken can only be created by BaseTable, and is only ever constructed inside this method.

This function expects Record subclasses to have a constructor signature of the form

Record(ConstructionToken const &, detail::RecordData &&, Args && ...);

Definition at line 227 of file BaseRecord.h.

                                                                  {
     return std::make_shared<RecordT>(BaseRecord::ConstructionToken(0), _makeNewRecordData(),
                                      std::forward<Args>(args)...);
 }

◆ copyRecord() [1/2]

std::shared_ptr<SimpleRecord> lsst::afw::table::SimpleTable::copyRecord ( BaseRecord const & other )

inline

Deep-copy a record, requiring that it have the same schema as this table.

Regardless of the type or associated table of the input record, the type of the output record will be the type associated with this table and the record instance will be associated with this table.

Allowing derived-class records to be constructed from base-class records could be considered a form of type-slicing, but because we already demand that all records be constructable from nothing but a table, this isn't anything new.

Derived classes should reimplement by static-casting the output of BaseTable::copyRecord to the appropriate BaseRecord subclass.

This is implemented using makeRecord and calling record.assign on the results; override those to change the behavior.

Definition at line 184 of file Simple.h.

                                                                     {

◆ copyRecord() [2/2]

std::shared_ptr<SimpleRecord> lsst::afw::table::SimpleTable::copyRecord	(	BaseRecord const &	other,

         return std::static_pointer_cast<SimpleRecord>(BaseTable::copyRecord(other, mapper));
     }

◆ getBufferSize()

std::size_t lsst::afw::table::BaseTable::getBufferSize ( ) const

inherited

Return the number of additional records space has been already been allocated for.

Unlike std::vector::capacity, this does not factor in existing records in any way.

Definition at line 112 of file BaseTable.cc.

                                          {
     if (_manager) {
         return Block::getBufferSize(_schema.getRecordSize(), _manager);
     } else {
         return 0;
     }
 }

◆ getCoordKey()

static CoordKey lsst::afw::table::SimpleTable::getCoordKey ( )

inlinestatic

Key for the celestial coordinates.

◆ getIdKey()

static Key<RecordId> lsst::afw::table::SimpleTable::getIdKey ( )

inlinestatic

Get keys for standard fields shared by all references.

These keys are used to implement getters and setters on SimpleRecord. Key for the unique ID.

Definition at line 170 of file Simple.h.

170 { return getMinimalSchema().id; }

◆ getMetadata()

std::shared_ptr<daf::base::PropertyList> lsst::afw::table::BaseTable::getMetadata ( ) const

208 {}

◆ make() [1/2]

static std::shared_ptr<SimpleTable> lsst::afw::table::SimpleTable::make ( Schema const & schema )

inlinestatic

Construct a new table.

Parameters

[in] schema Schema that defines the fields, offsets, and record size for the table.

This overload sets the ID factory to IdFactory::makeSimple().

Definition at line 129 of file Simple.h.

                                                                  {

◆ make() [2/2]

std::shared_ptr< SimpleTable > lsst::afw::table::SimpleTable::make	(	Schema const &	schema,
		std::shared_ptr< IdFactory > const &	idFactory
	)

static

Construct a new table.

Parameters

[in]	schema	Schema that defines the fields, offsets, and record size for the table.
[in]	idFactory	Factory class to generate record IDs when they are not explicitly given. If null, record IDs will default to zero.

Note that not passing an IdFactory at all will call the other override of make(), which will set the ID factory to IdFactory::makeSimple().

Definition at line 75 of file Simple.cc.

                                                                                           {
     if (!checkSchema(schema)) {
         throw LSST_EXCEPT(lsst::pex::exceptions::InvalidParameterError,
                           "Schema for Simple must contain at least the keys defined by makeMinimalSchema().");
     }
     return std::shared_ptr<SimpleTable>(new SimpleTable(schema, idFactory));
 }

◆ makeMinimalSchema()

static Schema lsst::afw::table::SimpleTable::makeMinimalSchema ( )

inlinestatic

Return a minimal schema for Simple tables and records.

The returned schema can and generally should be modified further, but many operations on SimpleRecords will assume that at least the fields provided by this routine are present.

Definition at line 140 of file Simple.h.

                                       {
         Schema r = getMinimalSchema().schema;
         r.disconnectAliases();
         return r;
     }

◆ makeRecord()

std::shared_ptr<SimpleRecord> lsst::afw::table::SimpleTable::makeRecord ( )

inline

Default-construct an associated record.

Derived classes should reimplement by static-casting the output of _makeRecord to the appropriate BaseRecord subclass to simulate covariant return types.

Definition at line 179 of file Simple.h.

                                              {

◆ popMetadata()

std::shared_ptr<daf::base::PropertyList> lsst::afw::table::BaseTable::popMetadata ( )

inlineinherited

Return the metadata and set the internal metadata to a null pointer.

Definition at line 85 of file BaseTable.h.

                                                      {
         std::shared_ptr<daf::base::PropertyList> tmp;
         _metadata.swap(tmp);
         return tmp;
     }

◆ preallocate()

void lsst::afw::table::BaseTable::preallocate ( std::size_t nRecords )

inherited

Allocate contiguous space for new records in advance.

If a contiguous memory block for at least n additional records has already been allocated, this is a no-op. If not, a new block will be allocated, and any remaining space on the old block will go to waste; this ensures the new records will be allocated contiguously. Note that "wasted" memory is not leaked; it will be deallocated along with any records created from that block when those records go out of scope.

Note that unlike std::vector::reserve, this does not factor in existing records in any way; nRecords refers to a number of new records to reserve space for.

Definition at line 110 of file BaseTable.cc.

110 { Block::preallocate(_schema.getRecordSize(), n, _manager); }

◆ setIdFactory()

void lsst::afw::table::SimpleTable::setIdFactory ( std::shared_ptr< IdFactory > f )

inline

Switch to a new IdFactory – object that generates IDs for the table (may be null).

Definition at line 161 of file Simple.h.

161 { _idFactory = f; }

◆ setMetadata()

void lsst::afw::table::BaseTable::setMetadata ( std::shared_ptr< daf::base::PropertyList > const & metadata )
