getInstance

public static SquirrelProvider getInstance()

setInstance

public static void setInstance(SquirrelProvider instance)

newInstance

public <T> T newInstance(TypeReference<T> typeRef)

newInstance

public <T> T newInstance(TypeReference<T> typeRef,
                Class<?>[] argTypes,
                Object[] args)

newInstance

public <T> T newInstance(Class<T> clz)

Create a new instance of the requested class using the internal registry.

Type Parameters:

T - type of new instance

Parameters:

clz - class of new instance

Returns:

new instance

newInstance

public <T> T newInstance(Class<T> clz,
                Class<?>[] argTypes,
                Object[] args)

Create a new instance of the requested class using the internal registry.

Type Parameters:

T - type of new instance

Parameters:

clz - class of new instance

argTypes - arguments type of new instance constructor

args - arguments of new instance constructor

Returns:

new instance

register

public void register(Class<?> clazz,
            Class<?> implementationClass)

Register the implementation class for a certain class. Note, if there is already an entry in the registry for the class, then it will be overwritten.

Parameters:

clazz - register class

implementationClass - implementation class of register class

unregister

public void unregister(Class<?> clazz)

clearRegistry

public void clearRegistry()

getImplementation

public <T> Class<T> getImplementation(Class<T> clz)

Return the current registered implementation. If class has register a implementation class, return register implementation class. If register class or implement class is an interface, try to find corresponding implementation class over naming convention. (implementation class simple name = interface class simple name + "Impl") First try to find the implementation class with conventional naming under the same package as interface class. If still not exist, try to find implementation class in (interface class package + ".impl").

Parameters:

clz - registered class

Returns:

current registered implementation
