Detailed Description

Transforms a mutable object to an immutable object.

If an object supports IFreezable interface, it is possible to transform it to immutable object. Once the object is frozen, it should not allow to change any of its properties or internal state.

Public Member Functions
virtual ErrCode INTERFACE_FUNC	freeze ()=0
	Makes the object frozen/immutable. It should return OPENDAQ_IGNORED value if the object is already frozen.
virtual ErrCode INTERFACE_FUNC	isFrozen (Bool *isFrozen) const =0
	Checks if the objects is frozen/immutable. More...
Public Member Functions inherited from IBaseObject
virtual ErrCode INTERFACE_FUNC	borrowInterface (const IntfID &intfID, void **obj) const =0
	Returns another interface which is supported by the object without incrementing the reference count. More...
virtual ErrCode INTERFACE_FUNC	dispose ()=0
	Disposes all references held by the object. More...
virtual ErrCode INTERFACE_FUNC	getHashCode (SizeT *hashCode)=0
	Returns hash code of the object. More...
virtual ErrCode INTERFACE_FUNC	equals (IBaseObject *other, Bool *equal) const =0
	Compares object to another object for equality. More...
virtual ErrCode INTERFACE_FUNC	toString (CharPtr *str)=0
	Returns a string representation of the object. More...
Public Member Functions inherited from IUnknown
virtual ErrCode INTERFACE_FUNC	queryInterface (const IntfID &intfID, void **obj)=0
	Returns another interface which is supported by the object and increments the reference count. More...
virtual int INTERFACE_FUNC	addRef ()=0
	Increments the reference count for an interface on an object. More...
virtual int INTERFACE_FUNC	releaseRef ()=0
	Decrements the reference count for an interface on an object. More...
