Member Function Documentation

HGL::IType * Poly::attachType ( IType *  type, const HGL::IType::TYPELIST::iterator &  before, bool  check  ) throw ( Exception::AttachException )

protectedvirtual

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

Referenced by HGL::Type::Curve::attachType().

void Poly::detachType ( IType *  type )

protectedvirtual

Detaches a child from the IType.

Parameters

type	the IType to detach

Since

0.5.21

Reimplemented from HGL::Type::TypeBase.

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

const Fill * Poly::getFill ( ) const

virtual

Gets the Fill type of the type.

Returns the last attached type if it is a Fill type

See Also

Poly::isValid

Returns

a Fill or NULL if none available

Implements HGL::Type::IFillable.

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

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

protectedvirtual

Gets the SerialID of HGL::IType::SPOLY

Returns

HGL::IType::SPOLY

Implements HGL::IType.

Reimplemented in HGL::Type::Curve.

References HGL::IType::SPOLY.

bool Poly::isValid ( ) const

virtual

Checks if the type is valid.

To be a valid Poly the Fill, if attached, must be the last attached type and it must contain at least two valid attached types.

Note

This method returns true if a reference is set, but not checking if the reference itself is valid. 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

Reimplemented from HGL::Type::ReferenceHolderBase.

Reimplemented in HGL::Type::Curve.
