Instance Method Details

#[](key) ⇒ Object

Retrieves the value object corresponding to the key object. The key is automatically converted to a string.

Parameters:

  • key (Symbol, String) —

    The key to look up.

Returns:

  • (Object) —

    The value associated with the key.

def [](key)
  super(convert_key(key))
end

#[]=(key, value) ⇒ Object

Associates the value given by value with the key given by key. The key is automatically converted to a string. The value is processed to ensure nested structures are also indifferent.

Parameters:

  • key (Symbol, String) —

    The key to store.

  • value (Object) —

    The value to store.

Returns:

  • (Object) —

    The stored value.

end

#fetch(key, *args) ⇒ Object

Returns a key’s value, or the default value if the key is not found. The key is automatically converted to a string.

Parameters:

  • key (Symbol, String) —

    The key to look up.

  • args (Array) —

    Optional default value or block.

Returns:

  • (Object) —

    The value associated with the key.

#key?(key) ⇒ Boolean Also known as: include?, has_key?, member?

Returns true if the given key is present in the hash. The key is automatically converted to a string.

Parameters:

  • key (Symbol, String) —

    The key to check.

Returns:

  • (Boolean) —

    True if the key exists, false otherwise.
