All Implemented Interfaces:

Serializable

public class QueryFieldInfo
extends Object
implements Serializable

Contains information about a field in the query

    { field; 'x.y', op:'=', rvalue= }
 

• fieldNameInClause: x.y
• fullFieldName: x.y
• fieldMd: Metadata node for x.y
• fieldEntity: The metadata for the entity containing x.y
• entityRelativeFieldName: x.y, the relative field name of the field in the entity containing it, as it appears in clause
• entityRelativeFieldNameWithContext: x.y, the relative field name of the field in the entity containing it, including any enclosing arrays
• clause: The query clause
• leaf: true (whether of not the field is used in an actual comparison)

  { array: 'a.b', elemMatch: { field:'x.y', op:'=',rvalue:} }
 

• fieldNameInClause: x.y
• fullFieldName: a.b.*.x.y
• entityRelativeFieldName: If a.b.* is a reference field, entity relative field name is x.y.
• entityRelativeFieldNameWithContext: If a.b.* is a reference field, entity relative field name is a.b.*.x.y.
• clause: {field:'x.y', op:'=',rvalue:}
• leaf: For a.b, false, for a.b.*.x.y, true
