1. Instance methods

checkbox → Boolean, Hash

checkbox of Page property returns the boolean property values of the page.
checkbox of Database or DataSource property returns the schema Hash. For Checkbox property, it is an empty Hash {}.
```
page.properties["CheckboxTitle"].checkbox
# => true
ds.properties["CheckboxTitle"].checkbox
# => {}
```

[P] checkbox=(value)

[PARAM] value new boolean value

checkbox=(value) of Page property sets the boolean property value of the page and sets will_update_flag to true.
Set true or false as value. Checkbox property cannot be set to nil; use false when the checkbox is unchecked.

checkbox=(value) of Database or DataSource property raises StandardError.

page.properties["CheckboxTitle"].checkbox = true
# => true

page.properties["CheckboxTitle"].checkbox = false
# => false

ds.properties["CheckboxTitle"].checkbox = true
# ...:in `assert_page_property': checkbox= can execute only Page property. (StandardError)

### only RollupProperty (number)
ds.properties["RollupTitle"].filter_does_not_equal 100, another_type: "number"

filter_equals(value) → Query

[PARAM] value value for filter

### only RollupProperty (date)
ds.properties["RollupTitle"].filter_equals Date.new(2022, 5, 7), another_type: "date"
# => #<NotionRubyMapping::Query:0x000000010925b480 @filter={"property"=>"RollupTitle", "date"=>{"equals"=>"2022-05-07"}}, @page_size=100, @sort=[], @start_cursor=nil>
