@groovy.transform.CompileStatic class EnumType extends AbstractMappingAwareCustomTypeMarshaller<java.lang.Object, org.bson.Document, org.bson.Document>
A custom type for persisting Enum which have an id field in domain classes. For example: To save identity instead of string in database for field type.
class User {
UserType type
String name
}
enum UserType {
A(1), B(2)
final int id
UserType(int id) {
this.id = id
}
}

Get type of collection by looking at hasMany static field in
the domain class.
@Example: Will return String class for list of String mapped by hasMany.
For custom user types, GORM return an empty map where our custom value needs to be inserted. For example: If our code is something like this:
User.withCriteria {
or {
eq("name", "admin")
eq("status", UserStatus.ACTIVE)
}
eq("foo", "bar")
}
Then the query we receive will be like:
[$and: [[$or: [["name": "admin"], [:]]], ["foo": "bar"]]
Now we have to place value of status to the blank field.
This method searches that empty place and put the value to the right place.
