class Eth::Abi::Type

def parse(type, components = nil, component_name = nil)

Raises:
  • (ParseError) - if it fails to parse the type.

Returns:
  • (Eth::Abi::Type) - a parsed Type object.

Parameters:
  • component_name (String) -- the tuple component's name.
  • components (Array) -- the components attribute.
  • type (String) -- a common Solidity type.
