Detailed Description

Holds information for read DS9 regions.

A DS9Region consists of a type, a list of coordinates, a coordinate system, and a set of properties. Composite regions also have a list of children regions. For simplicity, properties are either bool properties or String properties. All properties have defaults which are set during construction.

Member Function Documentation

bool casa::DS9Region::boolValue ( const String & property )

Returns the value for the given bool property.

bool casa::DS9Region::checkCoordinates ( )

Returns true if this region's coordinates are valid, false otherwise.

If the coordinates are invalid, this method will attempt to fix them first.

bool casa::DS9Region::checkProperties ( )

Returns true if this region's properties are valid, false otherwise.

If the properties are invalid, this method will attempt to fix them first.

static bool casa::DS9Region::defaultBoolValue ( const String & property ) [inline, static]

Returns the default value for the given bool property.

static String casa::DS9Region::defaultStringValue ( const String & property ) [inline, static]

Returns the default value for the given String property.

bool casa::DS9Region::define	(	const String &	property,
		bool	value
	)

Defines the given bool property with the given value.

Returns false if the given property is invalid.

bool casa::DS9Region::define	(	const String &	property,
		const String &	value
	)

Defines the given String property with the given value.

Returns false if the given property or value is invalid.

static bool casa::DS9Region::isBoolProperty ( const String & property ) [inline, static]

Returns true if the given String is a valid bool property, false otherwise.

bool casa::DS9Region::isDefined ( const String & property )

Returns true if the given property is defined, false otherwise.

const RFError& casa::DS9Region::lastError ( ) const

Returns the last error found during toRegionShape().

This error is only valid if toRegionShape() returns NULL which indicates an error was encountered.

Returns a name.

Note: when adding new properties: 1) add to properties(), DS9RegionFileWriter::globalProperties() (if necessary) 2) add to isBoolProperty() 3) for strings, add to valueIsValid 4) add to defaultBoolValue() or defaultStringValue() 5) if special printing is required, edit toPrintString, DS9RegionFileWriter::writeGlobals() 6) if special input is required, edit DS9RegionFileReader::readProperties()

Returns all valid properties.
