JSON Schema validating a range of numbers for a integer property

I'm using TV4 to validate my schema, and I saw that this lib use Json Schema model to validate a JSON.

But I didn't found a way to do a specific validation.

I have a integer property and this property can only have one of some numbers. For example, the valid number for me is, 10, 20, 30 and 40, so if I put some number different than these numbers, I need to show a validation error.

Has some way to do this specific validation in JSON Schema ?

You should be able to specify this JSON schema expression:

{
    "type"       : "number",
    "multipleOf" : 10,
    "maximum"    : 40,
    "minimum"    : 10
}

I'm not sure if you want an enum or you want your integer values to be multiples of 10.

For enum, you have an array of the allowed values. For example:

{
  "type": "string",
  "enum": ["red", "amber", "green"]
}

source

If you want values to be only multiples of a number, you want multipleOf.

{
    "type"       : "number",
    "multipleOf" : 10
}

source

These links are for the draft-4 version of JSON Schema, as that's what the library you're using supports, however these key words are also present in the lates version of JSON Schema (draft-7 at the time of writing). You may consider using a differnet library which supports newer versions.
