#subclasses(include_subclassed_nodes = false) ⇒ Array<Class>

Returns a list of classes that extend this class, directly or indirectly (as in subclasses of subclasses).

Examples:

# Given the following class heirarchy:
#   A
#   |
#   +--B
#   |  +--B1
#   |  +--B2
#   |
#   +--C

A.subclasses         # => [B1, B2, C]
A.subclasses(false)  # => [B1, B2, C]
A.subclasses(true)   # => [B, B1, B2, C]

Parameters:

  • include_subclassed_nodes (defaults to: false) —

    If true then classes extended by other classes are returned. If false then you only get the end nodes.
