Public Class methods

@overload [](hash)

  Creates a SymbolHash object from an existing Hash

  @example
    SymbolHash['x' => 1, :y => 2] # => #<SymbolHash:0x...>
  @param [Hash] hash the hash object
  @return [SymbolHash] a new SymbolHash from a hash object

@overload [](*list)

  Creates a SymbolHash from an even list of keys and values

  @example
    SymbolHash[key1, value1, key2, value2, ...]
  @param [Array] list an even list of key followed by value
  @return [SymbolHash] a new SymbolHash object

Creates a new SymbolHash object

@param [Boolean] symbolize_value converts any String values into Symbols

  if this is set to +true+.

Public Instance methods

Accessed a symbolized key @param [to_sym] key the key to access @return [Object] the value associated with the key

Assigns a value to a symbolized key @param [to_sym] key the key @param [Object] value the value to be assigned. If this is a String and

  values are set to be symbolized, it will be converted into a Symbol.

Deleted a key and value associated with it @param [to_sym] key the key to delete @return [void]

Tests if a symbolized key exists @param [to_sym] key the key to test @return [Boolean] whether the key exists

Merges the contents of another hash into a new SymbolHash object

@param [Hash] hash the hash of objects to copy @return [SymbolHash] a new SymbolHash containing the merged data

merge!(hash)

Alias for update

Updates the object with the contents of another Hash object. This method modifies the original SymbolHash object

@param [Hash] hash the hash object to copy the values from @return [SymbolHash] self
