dojox/json/schema (version 1.10)

The checkPropertyChange method will check to see if an value can legally be in property with the given schema This is slightly different than the validate method in that it will fail if the schema is readonly and it will not check for self-validation, it is assumed that the passed in value is already internally valid. The checkPropertyChange method will return the same object type as validate, see JSONSchema.validate for information.

This checks to ensure that the result is valid and will throw an appropriate error message if it is not

To use the validator call this with an instance object and an optional schema object. If a schema is provided, it will be used to validate. If the instance object refers to a schema (self-validating), that schema will be used to validate and the schema parameter is not necessary (if both exist, both validations will occur).

The validate method will return an object with two properties:

• valid: A boolean indicating if the instance is valid by the schema
• errors: An array of validation errors. If there are no errors, then an empty list will be returned. A validation error will have two properties:
• property: which indicates which property had the error
• message: which indicates what the error was
