22 | What is a method pool? | ||
23 | |||
24 | BitBake has a global method scope where .bb, .inc and .bbclass | ||
25 | files can install methods. These methods are parsed from strings. | ||
26 | To avoid recompiling and executing these string we introduce | ||
27 | a method pool to do this task. | ||
28 | |||
29 | This pool will be used to compile and execute the functions. It | ||
