Member Function Documentation

MyColor Graphwhiz::MyColor::generate

(

string

id

)

[static]

Generate a colour for id.

The method creates a "hash" value (an integer) from id. To create the three components of the colour, the method takes the modulus of the id with three prime numbers close to 255.

Note:

g++-4.5 spews error messages when using first declaration, as hash<*>::hash refers to a constructor, not a type. However, previous versions of GCC (revision < 154519) would accept such declaration: see BUG-report+Changlog-in-response to this bug here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11764#c19 We don't know in which gcc version this have been fixed but found that g++-4.5.2 no longer accepts it, so conditionally build it:
