By looking at the senders of #copyInContext:, I believe it is used in RBStringReplaceRule. By looking at this rule class comment, I believe it replaces a matched tree with another tree.
So I guess copyInContext: is used to replace a subtree of the AST by another tree. Regards, Clement 2014-06-17 17:06 GMT+02:00 Mark Rizun <mri...@gmail.com>: > What is the purpose of the mothod copyInContext: in AST-Core package? > > Thanks, > Mark >
