Public Member Functions
	plTypedMemberProperty (const char *szPropertyName)
	Passes the property name through to plAbstractMemberProperty.
virtual const plRTTI *	GetSpecificType () const override
	Returns the actual type of the property. You can then compare that with known types, eg. compare it to plGetStaticRTTI<int>() to see whether this is an int property.
virtual Type	GetValue (const void *pInstance) const =0
	Returns the value of the property. Pass the instance pointer to the surrounding class along.
virtual void	SetValue (void *pInstance, Type value) const =0
	Modifies the value of the property. Pass the instance pointer to the surrounding class along.
virtual void	GetValuePtr (const void *pInstance, void *pObject) const override
	Writes the value of this property in pInstance to pObject. pObject needs to point to an instance of this property's type.
virtual void	SetValuePtr (void *pInstance, const void *pObject) const override
	Sets the value of pObject to the property in pInstance. pObject needs to point to an instance of this property's type.
Public Member Functions inherited from plAbstractMemberProperty
	plAbstractMemberProperty (const char *szPropertyName)
	Passes the property name through to plAbstractProperty.
virtual plPropertyCategory::Enum	GetCategory () const override
	Returns plPropertyCategory::Member.
virtual void *	GetPropertyPointer (const void *pInstance) const =0
	Returns a pointer to the property data or nullptr. If a valid pointer is returned, that pointer and the information from GetSpecificType() can be used to step deeper into the type (if required).
Public Member Functions inherited from plAbstractProperty
	plAbstractProperty (const char *szPropertyName)
	The constructor must get the name of the property. The string must be a compile-time constant.
const char *	GetPropertyName () const
	Returns the name of the property.
const plBitflags< plPropertyFlags > &	GetFlags () const
	Returns the flags of the property.
plAbstractProperty *	AddFlags (plBitflags< plPropertyFlags > flags)
	Adds flags to the property. Returns itself to allow to be called during initialization.
plAbstractProperty *	AddAttributes (plPropertyAttribute *pAttrib1, plPropertyAttribute *pAttrib2=nullptr, plPropertyAttribute *pAttrib3=nullptr, plPropertyAttribute *pAttrib4=nullptr, plPropertyAttribute *pAttrib5=nullptr, plPropertyAttribute *pAttrib6=nullptr)
	Adds attributes to the property. Returns itself to allow to be called during initialization. Allocate an attribute using standard 'new'.
plArrayPtr< const plPropertyAttribute *const >	GetAttributes () const
	Returns the array of property attributes.
template<typename Type >
const Type *	GetAttributeByType () const
	Returns the first attribute that derives from the given type, or nullptr if nothing is found.

Detailed Description

template<typename Type>
class plTypedMemberProperty< Type >

The base class for all typed member properties. I.e. once the type of a property is determined, it can be cast to the proper version of this.

For example, when you have a pointer to an plAbstractMemberProperty and it returns that the property is of type 'int', you can cast the pointer to an pointer to plTypedMemberProperty<int> which then allows you to access its values.

Member Function Documentation

GetSpecificType()

template<typename Type >

virtual const plRTTI * plTypedMemberProperty< Type >::GetSpecificType ( ) const

inlineoverridevirtual

Returns the actual type of the property. You can then compare that with known types, eg. compare it to plGetStaticRTTI<int>() to see whether this is an int property.

Implements plAbstractProperty.

GetValue()

template<typename Type >

virtual Type plTypedMemberProperty< Type >::GetValue ( const void * pInstance ) const

pure virtual

Returns the value of the property. Pass the instance pointer to the surrounding class along.

Implemented in plAccessorProperty< Class, Type >, and plMemberProperty< Class, Type >.

GetValuePtr()

template<typename Type >

virtual void plTypedMemberProperty< Type >::GetValuePtr ( const void * pInstance, void * out_pObject ) const

inlineoverridevirtual

Writes the value of this property in pInstance to pObject. pObject needs to point to an instance of this property's type.

Implements plAbstractMemberProperty.

SetValue()

template<typename Type >

virtual void plTypedMemberProperty< Type >::SetValue ( void * pInstance, Type value ) const

pure virtual

Modifies the value of the property. Pass the instance pointer to the surrounding class along.

Note

Make sure the property is not read-only before calling this, otherwise an assert will fire.

Implemented in plMemberProperty< Class, Type >.

SetValuePtr()

template<typename Type >

virtual void plTypedMemberProperty< Type >::SetValuePtr ( void * pInstance, const void * pObject ) const

inlineoverridevirtual

Sets the value of pObject to the property in pInstance. pObject needs to point to an instance of this property's type.

Implements plAbstractMemberProperty.
