Assigns a new value to the hash:
hash = HashWithIndifferentAccess.new hash[:key] = "value"
# File lib/active_support/hash_with_indifferent_access.rb, line 44 44: def []=(key, value) 45: regular_writer(convert_key(key), convert_value(value)) 46: end
# File lib/active_support/hash_with_indifferent_access.rb, line 22 22: def default(key = nil) 23: if key.is_a?(Symbol) && include?(key = key.to_s) 24: self[key] 25: else 26: super 27: end 28: end
Removes a specified key from the hash.
# File lib/active_support/hash_with_indifferent_access.rb, line 120 120: def delete(key) 121: super(convert_key(key)) 122: end
Returns an exact copy of the hash.
# File lib/active_support/hash_with_indifferent_access.rb, line 99 99: def dup 100: HashWithIndifferentAccess.new(self) 101: end
# File lib/active_support/hash_with_indifferent_access.rb, line 9 9: def extractable_options? 10: true 11: end
Fetches the value for the specified key, same as doing hash[key]
# File lib/active_support/hash_with_indifferent_access.rb, line 83 83: def fetch(key, *extras) 84: super(convert_key(key), *extras) 85: end
Checks the hash for a key matching the argument passed in:
hash = HashWithIndifferentAccess.new hash["key"] = "value" hash.key? :key # => true hash.key? "key" # => true
# File lib/active_support/hash_with_indifferent_access.rb, line 74 74: def key?(key) 75: super(convert_key(key)) 76: end
Merges the instantized and the specified hashes together, giving precedence to the values from the second hash Does not overwrite the existing hash.
# File lib/active_support/hash_with_indifferent_access.rb, line 105 105: def merge(hash) 106: self.dup.update(hash) 107: end
Performs the opposite of merge, with the keys and values from the first hash taking precedence over the second. This overloaded definition prevents returning a regular hash, if reverse_merge is called on a HashWithDifferentAccess.
# File lib/active_support/hash_with_indifferent_access.rb, line 111 111: def reverse_merge(other_hash) 112: super self.class.new_from_hash_copying_default(other_hash) 113: end
# File lib/active_support/hash_with_indifferent_access.rb, line 115 115: def reverse_merge!(other_hash) 116: replace(reverse_merge( other_hash )) 117: end
# File lib/active_support/hash_with_indifferent_access.rb, line 125 125: def stringify_keys; dup end
# File lib/active_support/hash_with_indifferent_access.rb, line 124 124: def stringify_keys!; self end
# File lib/active_support/hash_with_indifferent_access.rb, line 127 127: def symbolize_keys; to_hash.symbolize_keys end
Convert to a Hash with String keys.
# File lib/active_support/hash_with_indifferent_access.rb, line 131 131: def to_hash 132: Hash.new(default).merge!(self) 133: end
# File lib/active_support/hash_with_indifferent_access.rb, line 128 128: def to_options!; self end
Updates the instantized hash with values from the second:
hash_1 = HashWithIndifferentAccess.new hash_1[:key] = "value" hash_2 = HashWithIndifferentAccess.new hash_2[:key] = "New Value!" hash_1.update(hash_2) # => {"key"=>"New Value!"}
# File lib/active_support/hash_with_indifferent_access.rb, line 60 60: def update(other_hash) 61: other_hash.each_pair { |key, value| regular_writer(convert_key(key), convert_value(value)) } 62: self 63: end
Returns an array of the values at the specified indices:
hash = HashWithIndifferentAccess.new hash[:a] = "x" hash[:b] = "y" hash.values_at("a", "b") # => ["x", "y"]
# File lib/active_support/hash_with_indifferent_access.rb, line 94 94: def values_at(*indices) 95: indices.collect {|key| self[convert_key(key)]} 96: end
# File lib/active_support/hash_with_indifferent_access.rb, line 136 136: def convert_key(key) 137: key.kind_of?(Symbol) ? key.to_s : key 138: end
# File lib/active_support/hash_with_indifferent_access.rb, line 140 140: def convert_value(value) 141: case value 142: when Hash 143: self.class.new_from_hash_copying_default(value) 144: when Array 145: value.collect { |e| e.is_a?(Hash) ? self.class.new_from_hash_copying_default(e) : e } 146: else 147: value 148: end 149: end
