public SPInterface(Class provider) 
{
                    
        this(provider, provider.getName());
}

Construct object representing Class provider.

Parameters:

provider - The SPI class

 public SPInterface(Class spi,
    String propertyName) 
{
        this.spi = spi;
        this.propertyName = propertyName;
}

Construct object representing Class provider.

Parameters:

spi - The SPI class

propertyName - when looking for the name of a class implementing the provider class, a discovery strategy may involve looking for (system or other) properties having either the name of the class (provider) or the propertyName.

 public SPInterface(Class provider,
    Class[] constructorParamClasses,
    Object[] constructorParams) 
{
        this(provider,
             provider.getName(),
             constructorParamClasses,
             constructorParams);
}

Construct object representing Class provider.

Parameters:

provider - The SPI class

constructorParamClasses - classes representing the constructor argument types.

constructorParams - objects representing the constructor arguments.

}

Construct object representing Class provider.

Parameters:
