create

protected Criteria create(Part part,
 Iterator<Object> iterator)

Specified by:

create in class AbstractQueryCreator<Query,Criteria>

and

protected Criteria and(Part part,
 Criteria base,
 Iterator<Object> iterator)

Specified by:

and in class AbstractQueryCreator<Query,Criteria>

or

protected Criteria or(Criteria base,
 Criteria criteria)

Specified by:

or in class AbstractQueryCreator<Query,Criteria>

complete

protected Query complete(@Nullable Criteria criteria,
 Sort sort)

Specified by:

complete in class AbstractQueryCreator<Query,Criteria>

in

protected Criteria in(Criteria criteria,
 Part part,
 Object param)

nin

protected Criteria nin(Criteria criteria,
 Part part,
 Object param)

regex

protected Criteria regex(Criteria criteria,
 Object param)

exists

protected Criteria exists(Criteria criteria,
 Object param)

empty

protected Criteria empty(MongoPersistentProperty property,
 Criteria criteria)

Modifies a criterion for the Part.Type.IS_EMPTY and Part.Type.IS_NOT_EMPTY keywords. Make sure to apply negation first for Part.Type.IS_NOT_EMPTY. For Collection properties, checks if the collection size is 0. For String properties, checks if the value equals an empty string and for Map and other types, checks if the value equals an empty document.

Parameters:

property - the targeted property within the domain model.

criteria - the criteria to modify.

Returns:

the criteria with empty semantics applied.

Since:

5.1

createContainingCriteria

protected Criteria createContainingCriteria(Part part,
 MongoPersistentProperty property,
 Criteria criteria,
 Object parameter)

If the target property of the comparison is of type String, then the operator checks for match using regular expression. If the target property of the comparison is a Collection then the operator evaluates to true if it finds an exact match within any member of the Collection.

Parameters:

part -

property -

criteria -

parameter -

Returns:
