| # Exports AppSearch Androidx code to Framework |
| # |
| # NOTE: This will remove and replace all files in the |
| # packages/modules/AppSearch path. |
| # |
| # Example usage (from root dir of androidx workspace): |
| # $ ./frameworks/support/appsearch/exportToFramework.py "$HOME/android/master" "<jetpack git sha>" |
| |
| # Special directives supported by this script: |
| # |
| # Causes the file where it appears to not be copied at all: |
| # @exportToFramework:skipFile() |
| # |
| # Causes the text appearing between startStrip() and endStrip() to be removed during export: |
| # // @exportToFramework:startStrip() ... // @exportToFramework:endStrip() |
| # |
| # Replaced with @hide: |
| # <!--@exportToFramework:hide--> |
| # |
| # Replaced with @CurrentTimeMillisLong: |
| # /*@exportToFramework:CurrentTimeMillisLong*/ |
| # |
| # Removes the text appearing between ifJetpack() and else(), and causes the text appearing between |
| # else() and --> to become uncommented, to support framework-only Javadocs: |
| # <!--@exportToFramework:ifJetpack()--> |
| # Jetpack-only Javadoc |
| # <!--@exportToFramework:else() |
| # Framework-only Javadoc |
| # --> |
| # Note: Using the above pattern, you can hide a method in Jetpack but unhide it in Framework like |
| # this: |
| # <!--@exportToFramework:ifJetpack()-->@hide<!--@exportToFramework:else()--> |
