1 This directory is for components that have the Content Module as the 2 uppermost layer they depend on. They may depend only on the Content 3 API (content/public) and on lower layers (e.g. base/, net/, ipc/ 4 etc.). 5 6 Components that have bits of code that need to live in different 7 processes (e.g. some code in the browser process, some in the renderer 8 process, etc.) should separate the code into different subdirectories. 9 Hence for a component named 'foo' you might end up with a structure 10 like the following: 11 12 components/foo - DEPS, OWNERS, foo.gypi 13 components/foo/browser - code that needs the browser process 14 components/foo/common - for e.g. IPC constants and such 15 components/foo/renderer - code that needs renderer process 16 17 These subdirectories should have DEPS files with the relevant 18 restrictions in place, i.e. only components/*/browser should 19 be allowed to #include from content/public/browser. 20 21 Note that there may also be an 'android' subdir, with a Java source 22 code structure underneath it where the package name is 23 org.chromium.components.foo, and with subdirs after 'foo' 24 to illustrate process, e.g. 'browser' or 'renderer': 25 26 components/foo/android/OWNERS, DEPS 27 components/foo/android/java/src/org/chromium/components/foo/browser/ 28 components/foo/android/javatests/src/org/chromium/components/foo/browser/ 29 30 Code in a component should be placed in a namespace corresponding to 31 the name of the component; e.g. for a component living in 32 //components/foo, code in that component should be in the foo:: 33 namespace. Note that it used to be the rule that all code under 34 //components should be in the components:: namespace; this is being 35 phased out. 36
