Interface UpdateConstraint.PartialJSON

All Superinterfaces:

UpdateConstraint

Enclosing interface:

UpdateConstraint

public static interface UpdateConstraint.PartialJSON
extends UpdateConstraint

A constraint requiring the current value of a JSON topic to match the partially described value.

The code:

 
 Constraint.Factory factory = Diffusion.updateConstraints();
 PartialJSON constraint =
     factory.jsonValue()
         .with("/id", String.class, idValue)
         .without("/cancellation");
 
 

creates a constraint for a JSON object with a specific ID value and no value for a "cancellation" property.

Missing keys are matched differently to keys that are present with null values.

with

<V> UpdateConstraint.PartialJSON with(String pointer,
                                      Class<V> valueClass,
                                      V value)

Require a value at a specific position in the JSON object.

The pointer is a JSON Pointer syntax reference locating the value in the JSON object.

Only string, int64, and double values are supported. The null value may be passed for any type.

Type Parameters:

V - the value type of the value at the pointer

Parameters:

pointer - the pointer expression

valueClass - the value class

value - the value

Returns:

a new constraint

Throws:

IllegalArgumentException - if the pointer parameter cannot be parsed as a JSON pointer or if the value class is not one of String, Long or Double.

without

UpdateConstraint.PartialJSON without(String pointer)

Require a specific position in the JSON object to be absent. This does not match positions that have null values.

The pointer is a JSON Pointer syntax reference that should have no value in the JSON object.

Parameters:

pointer - the pointer expression

Returns:

a new constraint

Throws:

IllegalArgumentException - if the pointer parameter cannot be parsed as a JSON pointer
