public void initialize()
                throws OperatorException

Description copied from class: Operator

Initializes this operator and sets the one and only target product.

The target product can be either defined by a field of type Product annotated with the TargetProduct annotation or by calling Operator.setTargetProduct(org.esa.snap.core.datamodel.Product) method.

This method shall never be called directly. The framework calls this method after it has created an instance of this Operator. This will occur only once durting the lifetime of an Operator instance. If not already done, calling the Operator.getTargetProduct() will always trigger a call to the initialize() method.

Any client code that must be performed before computation of tile data should be placed here.

Specified by:

initialize in class Operator

Throws:

OperatorException - If an error occurs during operator initialisation.
