WriteTo

The WriteTo method writes this transform's matrix to the specified storage unit.

void WriteTo (in ODStorageUnit storageUnit);

storageUnit

A reference to the storage unit where this transform's matrix is to be written.

DISCUSSION

Before calling this method, you must focus the storage unit to the property where the matrix is to be written. This method writes the matrix into the value of type kODTransform in the focused property, replacing any matrix that was previously stored in that value or creating the value if it doesn't already exist.

OVERRIDING

If you subclass ODTransform to create a nonlinear transform class, you must override this method. Your override method can call its inherited method at any point in your implementation (it does not matter where).

EXCEPTIONS

kODErrUnfocusedStorageUnit

This storage unit is not focused on a property or a value.
