Getting a property (could be environment, properties files or Spring Context)

Utils4J provides a very flexible and convenient interface to retrive the properties from any source, the beauty is no need to define the source to get the property from, as given below:

final Object value = VarraProperties.getProperty("env"+ StringUtils.DOT + "property" + StringUtils.DOT + "name");
final String value = VarraProperties.getPropertyAsGeneric("file"+ StringUtils.DOT + "property" + StringUtils.DOT + "name");
final Student student = VarraProperties.getWrapperProperty("spring"+ StringUtils.DOT + "student", Student.class);

Features at a Glance

Utils4J provides flexible construction to create a property repository with a combination of the following features:

• Automatic way of loading the properties, optionally asynchronously.
• Time based eviction of properties, if you prefer to unload the entries.
• Flexible way to load the spring context, and make them available as part of repo.
• Automatic loading of system environment's properties and make them available as part of repo to an entire application.
• asynchronous way of refreshing/reloading the properties.
• Property values automatically wrapped in to the desired types.
• Provides an interface for storing the todo tasks.
• Asynchronous way of executing the tasks, maintains an in-memory based queue with fixed or unlimted based on configuration.
• Evicts the tasks if the queue is full and notifys the evicted tasks to the listener thread in an asynchrounous way.
• Provides an interface to perform some household work when the task is completed/failed.
• Misc utilities for day to day developer's usage.
