Throws:

java.lang.ClassNotFoundException

java.lang.IllegalAccessException

java.lang.InstantiationException

discoverDriverSupport

public DriverSupport discoverDriverSupport()

discoverAlgorithms

public java.util.Set<MaskingComponent> discoverAlgorithms()

Discovers the MaskingAlgorithm classes in the jar file location. The jar file location is scanned for all the jar files and classes stored in those jar file are tested for masking algorithm classes. A list of these algorithm classes are returned.

Returns:

Returns the list of objects of discovered Algorithm classes.

Throws:

DuplicateComponentNameException - if two algorithms in the jar have same name.

isBuiltIn

public boolean isBuiltIn()
