Public Member Functions
	ezTypedMemberProperty (const char *szPropertyName)
	Passes the property name through to ezAbstractMemberProperty.
virtual const ezRTTI *	GetSpecificType () const override
	Returns the actual type of the property. You can then compare that with known types, eg. compare it to ezGetStaticRTTI<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 ezAbstractMemberProperty
	ezAbstractMemberProperty (const char *szPropertyName)
	Passes the property name through to ezAbstractProperty.
virtual ezPropertyCategory::Enum	GetCategory () const override
	Returns ezPropertyCategory::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 ezAbstractProperty
	ezAbstractProperty (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 ezBitflags< ezPropertyFlags > &	GetFlags () const
	Returns the flags of the property.
ezAbstractProperty *	AddFlags (ezBitflags< ezPropertyFlags > flags)
	Adds flags to the property. Returns itself to allow to be called during initialization.
ezAbstractProperty *	AddAttributes (ezPropertyAttribute *pAttrib1, ezPropertyAttribute *pAttrib2=nullptr, ezPropertyAttribute *pAttrib3=nullptr, ezPropertyAttribute *pAttrib4=nullptr, ezPropertyAttribute *pAttrib5=nullptr, ezPropertyAttribute *pAttrib6=nullptr)
	Adds attributes to the property. Returns itself to allow to be called during initialization. Allocate an attribute using standard 'new'.
ezArrayPtr< const ezPropertyAttribute *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 ezTypedMemberProperty< 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 ezAbstractMemberProperty and it returns that the property is of type 'int', you can cast the pointer to an pointer to ezTypedMemberProperty<int> which then allows you to access its values.

Member Function Documentation

GetSpecificType()

template<typename Type >

virtual const ezRTTI * ezTypedMemberProperty< Type >::GetSpecificType ( ) const

inlineoverridevirtual

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

Implements ezAbstractProperty.

GetValue()

template<typename Type >

virtual Type ezTypedMemberProperty< 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 ezResourceAccessorProperty< Class, Type >, ezAccessorProperty< Class, Type >, and ezMemberProperty< Class, Type >.

GetValuePtr()

template<typename Type >

virtual void ezTypedMemberProperty< 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 ezAbstractMemberProperty.

SetValue()

template<typename Type >

virtual void ezTypedMemberProperty< 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 ezResourceAccessorProperty< Class, Type >, and ezMemberProperty< Class, Type >.

SetValuePtr()

template<typename Type >

virtual void ezTypedMemberProperty< 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 ezAbstractMemberProperty.
