Member Function Documentation

getAlias()

std::string lsst::afw::table::SlotDefinition::getAlias ( ) const

inlineinherited

Return the alias field prefix used to lookup Keys for the slot.

This simply prepends "slot_" to the slot name.

Definition at line 60 of file slots.h.

{ return "slot_" + _name; }

getErrKey()

ErrKey lsst::afw::table::CentroidSlotDefinition::getErrKey ( ) const

inline

Return the cached Key used to access the slot uncertainty.

Definition at line 137 of file slots.h.

{ return _errKey; }

getFlagKey()

Key<Flag> lsst::afw::table::CentroidSlotDefinition::getFlagKey ( ) const

inline

Return the cached Key used to access the slot failure flag.

Definition at line 140 of file slots.h.

{ return _flagKey; }

getMeasKey()

MeasKey lsst::afw::table::CentroidSlotDefinition::getMeasKey ( ) const

inline

Return the cached Key used to access the slot measurement.

Definition at line 134 of file slots.h.

{ return _measKey; }

getName()

std::string lsst::afw::table::SlotDefinition::getName ( ) const

inlineinherited

Return the name of the slot (e.g. "Centroid" or "PsfFlux")

Definition at line 53 of file slots.h.

{ return _name; }

isValid()

bool lsst::afw::table::CentroidSlotDefinition::isValid ( ) const

inline

Return true if the key associated with the measurement is valid.

Definition at line 131 of file slots.h.

{ return _measKey.isValid(); }

operator=() [1/2]

CentroidSlotDefinition& lsst::afw::table::CentroidSlotDefinition::operator= ( CentroidSlotDefinition &&  )

default

operator=() [2/2]

CentroidSlotDefinition& lsst::afw::table::CentroidSlotDefinition::operator= ( CentroidSlotDefinition const &  )

default

setKeys()

void lsst::afw::table::CentroidSlotDefinition::setKeys	(	std::string const &	alias,
		Schema const &	schema
	)

Update the cached Keys following an change of aliases in the given Schema.

This method is intended for internal use by SourceTable only.

Parameters

[in]	alias	If non-empty, abort early if this string does not start with getAlias() (used to see if an alias change might have affected this slot, and avoid unnecessary work if not).
[in]	schema	Schema to search for Keys.
