Method Detail

factory

public F factory()

Main method of this factory. This method makes classes from the class names defined in environment variables. Such variables are defined by each concrete factory, which implement the abstract factory through the getVariableName () method. Once the environment variable is read, the value of the variable is stored in the "className" property. If the environment variable is not set, a default object is built using the abstract method called factoryDefault().

Returns:

factory instance

factoryFromClassName

protected F factoryFromClassName(String className)

Instantiate an object from the name of this class

Parameters:

className - class name to create

Returns:

instance of factory for class

factoryDefault

public abstract F factoryDefault()

It forces the concrete class to fabricate an default object

Returns:

instance of default factory

getVariableName

protected abstract String getVariableName()

Every concrete factory must define in which environment variable it contains the name of the class to be fabricated.

Returns:

variable name
