Method Detail

canMakeInstances

public static boolean canMakeInstances(java.lang.Class<?> clazz)

Returns true iff we can make instances of this class. Note that this will return false if the class does not have any public constructors.

makeInstancesOfSubclasses

public static <T> java.util.List<T> makeInstancesOfSubclasses(java.lang.Class<? extends T> clazz,
                                                              java.lang.Package pack)

Finds and creates objects of all concrete subclasses of the given class in the package. The public no-arg constructor is called to create the objects. GATKException is thrown if creation of any object fails.

Parameters:

clazz - class to be instantiated

pack - package in which the class will be searched for

makeInstanceOf

public static <T> T makeInstanceOf(java.lang.Class<T> clazz)

Create objects of a concrete class. The public no-arg constructor is called to create the objects.

Parameters:

clazz - class to be instantiated

Returns:

new object or null if cannot be instantiated.

knownSubInterfaceSimpleNames

public static java.util.List<java.lang.String> knownSubInterfaceSimpleNames(java.lang.Class<?> iface)

Finds sub-interfaces of the given interface (in the same package) and returns their simple names.

knownSubInterfaces

public static java.util.Set<java.lang.Class<?>> knownSubInterfaces(java.lang.Class<?> iface)

Finds all subinterfaces of the given interface (in the same package).

getClassesOfType

public static java.util.List<java.lang.Class<?>> getClassesOfType(java.lang.Class<?> targetClass,
                                                                  java.util.List<java.lang.Class<?>> classesToSearch)

Gets a list of classes that are either the same as, or a subclass/subinterface of a parent target class.

Parameters:

targetClass - Parent Class for which to check for inheritance.

classesToSearch - Classes to check for inheritance against targetClass.

Returns:

List of classes from classesToSearch that inherit from targetClass.
