Method Detail

buildIndexInterruptibly

void buildIndexInterruptibly()
                      throws java.lang.InterruptedException

Instructs this class locator to start building its index for locating files. This method runs on the current thread and blocks until the index build is completed. To build the index in the background, call this method on a background thread.

Throws:

java.lang.InterruptedException - if the build is interrupted

getPackagesInterruptibly

java.util.Collection<java.lang.String> getPackagesInterruptibly(java.lang.String packagePrefix)

Fetch the list of subpackages within the given package. To get a list of top-level packages, use an empty, "", prefix. The names of the subpackages will not contain the package prefix.

Parameters:

packagePrefix - the package prefix, i.e., "java.io"

Returns:

a collection of (String) subpackage names in the given package
