Member Function Documentation

base_island_ptr pagmo::island::clone ( ) const

virtual

Clone method.

Provided that the derived island implements properly the copy constructor, virtually all implementations of this method will look like this:

return base_ptr(new derived_island(*this));

Returns: pagmo::base_island_ptr to a copy of this.

Implements pagmo::base_island.

Definition at line 70 of file island.cpp.

std::string pagmo::island::get_name ( ) const

virtual

Return a string identifying the island's type.

Default implementation will return the island's C++ mangled name.

Returns: a string identifying the island's type.

Reimplemented from pagmo::base_island.
