# Object Validator

Determines whether the tested value is an object.

The [utils.isObject()][utils/utils.isObject()] is used internally.

```javascript
var schema = new Schema({
  dict: {
    object: true
  }
});

console.log(utils.catchError(schema.validate, schema, [{dict: 'text'}])+'');
// "SchemaError: dict must be an object"

console.log(utils.catchError(schema.validate, schema, [{dict: null}])+'');
// "SchemaError: Required property dict not found"

console.log(schema.validate({dict: {}}));
// true
```

This validator accepts the properties array used to describe the allowed properties.

```javascript
var schema = new Schema({
  dict: {
    object: {
      properties: ['name', 'age']
    }
  }
});

console.log(utils.catchError(schema.validate, schema, [{dict: { address: 'abc' }}])+'');
// "SchemaError: dict doesn't provide address property"

console.log(schema.validate({dict: { name: 'John' }}));
// true
```

    assert = require 'src/assert'
    utils = require 'src/utils'

    module.exports = (Schema) -> (row, value, expected) ->
        unless expected
            return

        unless utils.isObject(value)
            throw new Schema.Error row, 'object', "#{row} must be an object"

        # available properties
        if props = expected?.properties
            assert.isArray props

            for prop of value
                unless ~props.indexOf prop
                    throw new Schema.Error row, 'object.properties', "#{row} doesn't provide #{prop} property"

        return
