Member Function Documentation

const Fill * Ellipse::getFill ( ) const

virtual

Gets the Fill type of the type.

Returns

a Fill or NULL if none available

Implements HGL::Type::IFillable.

References HGL::Type::TypeBase::getAttachedTypes().

HGL::IType::SERIALID Ellipse::getSerialID ( ) const

protectedvirtual

Gets the SerialID of HGL::IType::SELLIPSE

Returns

HGL::IType::SELLIPSE

Implements HGL::IType.

References HGL::IType::SELLIPSE.

Referenced by isValid().

bool Ellipse::isValid ( ) const

virtual

Checks if the type is valid.

An Ellipse is valid if the

1. type is a Point
2. type is a Vector2D

Note

this method returns false if the type has no attached subtypes. A type is valid

1. if all attached types are allowed for this type, if not the type is invalid
2. if all attached types itself are valid, if not the type is invalid

Subclasses can add more checks if neccessary.

Returns

true if the type is valid, false otherwise
