EnumeratedEntityTransformer

An EnumeratedEntityTransformer gives the Nth entity an accessible ${<entity>.n} == N. In addition, the entity may specify a chunkSize attribute, which will cause the chunkSize'th entity to gain the attribute $hasMore=true. A template for a nextUrl may also be specified on the entity, that is different from the url template.

Consider an API:

http://host:port/path/to/resource?maximum_number_returned=50&return_start_index=0

an entity could specify:

<entity name="myEntity" processor="XPathEntityProcessor" transformer="EnumeratedEntityTransformer" url="http://host:port/path/to/resource?maximum_number_returned=50&return_start_index=${myEntity.n}" chunkSize=50>...</entity>

This allows for fetching entities in chunks until there are < chunkSize returned.
