#encode(data, separator = "") ⇒ Array<Hash{ Symbol => Object }>

Check and then pass data to the actual encoder.

Parameters:

  • data (Array, String, Enumerator) —

    Data to encode.

  • separator (String, Regexp) (defaults to: "") —

    (“”) Separator for the string arguments.

Returns:

  • (Array<Hash{ Symbol => Object }>) —

    Encoded data. Each element is a Hash with the following key-value pairs:

    [Constants::CHUNK_KEY => Object]
  A repeated object.

[Constants::COUNT_KEY => Integer]
  How many times the object is repeated.

Raises:
