Detailed Description

Basic property descriptor interface.

A property descriptor provides a uniform way to change the value of a simple property. The values are safely wrapped inside an Ogre::Any.

This only works for simple properties which are copied by value. This includes floats strings and vectors but not things like Entity pointers.

All public methods are const because the descriptor itself is not modified by these methods.

Member Function Documentation

virtual bool Caelum::ValuePropertyDescriptor::canGetValue ( ) const

pure virtual

If the value of the property can be read (true means write-only).

This is false for write-only properties. Write-only properties are generally a bad idea but they are supported. Scripting (with .os files) doesn't actually require reading existing values.

Implemented in Caelum::AccesorPropertyDescriptor< TargetT, ParamT, InParamT, OutParamT >.

virtual const Ogre::Any Caelum::ValuePropertyDescriptor::getValue ( const void * target ) const

pure virtual

Get the value of the property packed in an Ogre::Any.

Parameters

target Object to fetch the property from. If target is not of the correct type behaviour is undefined.

virtual void Caelum::ValuePropertyDescriptor::setValue	(	void *	target,
		const Ogre::Any &	value
	)		const

pure virtual

Set the value of the property packed in an Ogre::Any.

Parameters

target	Object set the property on. If target is not of the correct type then behaviour is undefined.
value	New value of the property.

virtual bool Caelum::ValuePropertyDescriptor::implementsTypedValuePropertyDescriptor ( ) const

inlinevirtual

Check if this class also implements TypedValuePropertyDescriptor.

If this property returns true then you can static_cast this object to a TypedValuePropertyDescriptor<ValueT>; for the appropiate ValueT. The appropriate ValueT can be obtained with getValueTypeId.
