Hi,
I'll like to know what is happening exactly in background when I'm using a symbol as in *Collection withAllSubclasses collect: #numberOfLinesOfCode*.
Nicolas has a good answer. Now you could explore this yourself. First, as a reference inspect "Collection withAllSubclasses" on its own. Then try debugging into the expression (from the context menu in the Playground.) In particular in OrderedCollection>>collect: step-INTO "aBlock value: ....." For an even lower level (probably too low), try debugging into... OpalCompiler compile: 'Collection withAllSubclasses collect: #numberOfLinesOfCode' or more simply debug... OpalCompiler compile: '#numberOfLinesOfCode inspect'. Other things you could explore * Look at the class comment for class Symbol * Look at the tests of class SymbolTest * In the Browser with class Symbol selected, right-click and choose Analyze>Class refs. cheers -ben
I also want to know the other cases where I can use symbol.
Is there any tutorial about using symbol?
Thanks
