This is about making the JPPF APIs fluent wherever applicable, as we have already done for the configuration API.

Basically, we want to refactor the modifiers in these public APIs such that they return an instance of the object they modify without type casting. This allows method calls chaining and makes the code both more readable and more compact. When the modifiers belong to multiple classes in the same class or interface hierarchy, we might need to genericize them to use the compiler's inherent type inference capabilities.

Some candidate APIs:

• job SLA
• JPPFJob / AbstractJPPFJob
• Metadata / Metadata
• Task / AbstractTask hierarchy
• ... ?
