xref: https://issues.redhat.com/browse/ENTESB-12403

Support indexed collection field path expression like /Email<1>, also range like /Email<0-3,5>.

Map items of a collection at defined indexes e.g.

/Company<0,1,5>/Person<0-9>/fullName -> Person<b>/fullName

=> The target will contain only 30 items from source

"Map items of a collection at defined indexes e.g.

Person<0-9>/fullName -> Person<b>/fullName

=> The target will contain only 10 items from source"

It needs some way to manually edit collection indexes in the expression. Currently it shows as label and collection index is not accessible.

feat: Support dynamic path expression resolution
2af150b 
Fixes: atlasmap#1512
Instead of having expression as a transformation, this will bring `<Document ID>:</path/to/field>` syntax of path expression directly into expression parser. It allows expression to support more complex cases like FILTER and SELECT.
This partially addresses atlasmap#1507, but in order to have it working for real usecase, atlasmap#1562 has to be addressed for each FieldReader of java/json/xml.
Also, this supports specifying single index on a field (atlasmap#1187).
