public class AnalyzeQuery
extends QueryIterator

Analyzes a query to collect field information. For each field in a query, these are collected:

• fieldNameInClause: Name of the field as it appears in the smallest clause containing it.
• fullFieldName: Full name of the field as known to the query. For fields in an array elemMatch query, this is the name of the field containing the array name and field name under the array.
• fieldMd: Metadata node for the field
• fieldEntity: The metadata for the entity containing the field
• entityRelativeFieldName: The relative field name of the field in the entity containing it
• clause: The query clause
