ios - Should we define a position to CCAnimation? -

-
well, asking question ccanimation example in book " learn cocos2d ". in example (ch6), don't see code define position ccanimation , see ccsprite-derived class, called "ship", given position. why? ccanimation knows animate? thanks ccanimation has no position. animation changes sprite frames (textures) of sprite (the ship). therefore ship's position determines animation played.

java - Clojure Reflection warning - call to write can't be resolved -

-
i'm struggling correct type hints avoid warn on reflection while writing text-file-output database query. i've tried put ^string type hints before each function being called, output going hit text file on disk. the reflection warning occurs on :row-fn line towards end of function. have comment reflection warning, dbdump/dbdump.clj:157:44 - call write can't resolved. on same line. how can rid of warning? i'm thinking there performance cost when working large datasets. (defn run-job [job-time-string db-spec config] (let [; {{{ source-sql (str "select * " (:source-base-name config)(:table-name config)) max-rows (:max-rows config) fetch-size (:fetch-size config) working-dir (:working-dir config) output-name (str working-dir "/" job-time-string ".pipe" ) field-delim (:field-delim config)
