A rule object is a logical container for components and filters that manipulate a piece of an input transaction to produce a part of the output transaction. Once the input data is placed into field objects, transaction production starts with the first rule object in the production object and continues through each rule object in presentation sequence.
Each rule object contains:
One or more rule component objects, which operate on the individual field objects. Component objects are executed in serial order.
A storage area, called a blob, where the output from the rule components is assembled. As the output of each rule component is generated, it is appended to the blob.
One or more filters, which operate on the blob after all rule components have finished processing.
