SchemaArrayOptions

The options defined on an Array schematype.

Example:

const schema = new Schema({ tags: [String] });
schema.path('tags').options; // SchemaArrayOptions instance

If set to false, will always deactivate casting non-array values to arrays. If set to true, will cast non-array values to arrays if init and SchemaArray.options.castNonArrays are also true

Example:

const Model = db.model('Test', new Schema({ x1: { castNonArrays: false, type: [String] } }));
const doc = new Model({ x1: "some non-array value" });
await doc.validate(); // Errors with "CastError"

If this is an array of strings, an array of allowed values for this path. Throws an error if this array isn't an array of strings.

If set, specifies the type of this array's values. Equivalent to setting type to an array whose first element is of.

Example:

// `arr` is an array of numbers.
new Schema({ arr: [Number] });
// Equivalent way to define `arr` as an array of numbers
new Schema({ arr: { type: Array, of: Number } });
