Prototype

boolean isEmpty();

Source Link

Document

Returns true if this multimap contains no key-value pairs.

Usage

From source file:com.google.idea.blaze.android.rendering.BlazeRenderErrorContributor.java

/**
 * Blaze doesn't resolve class dependencies from resources until building the final
 * android_binary, so we could end up with resources that ultimately build correctly, but fail to
 * find their class dependencies during rendering in the layout editor.
