Thus far we've looked at how the [http://hg.mozilla.org/mozilla-central/file/0cd41f599080/xpcom/io/nsILocalFile.idl nsILocalFile.idl] interface is defined, and seen what happens when it gets translated into [[Education/Learning/UnderstandingXpcomFiles/nsILocalFile.h|nsILocalFile.h]]. | Thus far we've looked at how the [http://hg.mozilla.org/mozilla-central/file/0cd41f599080/xpcom/io/nsILocalFile.idl nsILocalFile.idl] interface is defined, and seen what happens when it gets translated into [[Education/Learning/UnderstandingXpcomFiles/nsILocalFile.h|nsILocalFile.h]]. | ||
Now it's time to look for an implementation of this interface. The relevant files are [http://hg.mozilla.org/mozilla-central/file/0cd41f599080/xpcom/io/nsLocalFile.h nsLocalFile.h] and [http://hg.mozilla.org/mozilla-central/file/0cd41f599080/xpcom/io/nsLocalFileCommon.cpp nsLocalFileCommon.cpp]. | Now it's time to look for an implementation of this interface.
