afMorphia::Queries

Convenience shortcut methods for creating Query objects. These values mimic those on QueryCriterion.

const class MyQueries : Queries {

    Query price() {
        return and([
            or([ eq("price", 0.99f), eq("price", 1.99f)  ]),
            or([ eq("sale", true),   lessThan("qty", 29) ])
        ])
    }

and

Source

Query and(Query q1, Query q2, Query? q3 := null, Query? q4 := null)

Selects documents that pass all the query expressions in the given list. Example:

query := and(
  lessThan("quantity", 20),
  eq("price", 10)
)

Note the above could also be written as:

lessThan("quantity", 20).and([eq("price", 10)])
