Interface UpdateOperations<T>

Type Parameters:

T - The Java type used in the updates

All Known Implementing Classes:

UpdateOpsImpl

public interface UpdateOperations<T>

A nicer interface to the update operations in monogodb. All these operations happen at the server and can cause the server and client version of the Entity to be different

Method Summary

Methods

Modifier and Type	Method and Description
UpdateOperations<T>	add(String fieldExpr, Object value) adds the value to an array field
UpdateOperations<T>	add(String fieldExpr, Object value, boolean addDups)
UpdateOperations<T>	addAll(String fieldExpr, List<?> values, boolean addDups) adds the values to an array field
UpdateOperations<T>	dec(String fieldExpr) decrements the numeric field by 1
UpdateOperations<T>	disableValidation() Turns off validation (for all calls made after)
UpdateOperations<T>	enableValidation() Turns on validation (for all calls made after); by default validation is on
UpdateOperations<T>	inc(String fieldExpr) increments the numeric field by 1
UpdateOperations<T>	inc(String fieldExpr, Number value) increments the numeric field by value (negatives are allowed)
UpdateOperations<T>	isolated() Enables isolation (so this update happens in one shot, without yielding)
UpdateOperations<T>	max(String fieldExpr, Number value) sets the numeric field to value if it is greater than the current value.
UpdateOperations<T>	min(String fieldExpr, Number value) sets the numeric field to value if it is less than the current value.
UpdateOperations<T>	removeAll(String fieldExpr, List<?> values) removes the values from the array field
UpdateOperations<T>	removeAll(String fieldExpr, Object value) removes the value from the array field
UpdateOperations<T>	removeFirst(String fieldExpr) removes the first value from the array
UpdateOperations<T>	removeLast(String fieldExpr) removes the last value from the array

decrements the numeric field by 1

inc

UpdateOperations<T> inc(String fieldExpr)

increments the numeric field by 1

inc

UpdateOperations<T> inc(String fieldExpr,
                      Number value)

Turns on validation (for all calls made after); by default validation is on

disableValidation

UpdateOperations<T> disableValidation()

Turns off validation (for all calls made after)

isolated
