Method Detail

addJarToPackages

public void addJarToPackages(java.net.URL jarurl)

Gathers classes info from jar specified by a URL. Eventually just using previously cached info. Eventually updated info is not cached. Persistent cache storage access goes through inOpenCacheFile() and outCreateCacheFile().

addJarToPackages

public void addJarToPackages(java.net.URL jarurl,
                             boolean cache)

Gathers classes info from jar specified by URL. Eventually just using previously cached info. Eventually updated info is (re-)cached if param cache is true. Persistent cache storage access goes through inOpenCacheFile() and outCreateCacheFile().

addJarToPackages

public void addJarToPackages(java.io.File jarfile)

Gathers classes info from jar specified by File jarfile. Eventually just using previously cached info. Eventually updated info is not cached. Persistent cache storage access goes through inOpenCacheFile() and outCreateCacheFile().

addJarToPackages

public void addJarToPackages(java.io.File jarfile,
                             boolean cache)

Gathers package and class lists from a jar specified by a File. Eventually just using previously cached info. Eventually updated info is (re-)cached if param cache is true. Persistent cache storage access goes through inOpenCacheFile() and outCreateCacheFile().

saveCache

public void saveCache()

Write back cache index. The index is a mapping from each source of class definitions to the file where the cache for that source is held. This list is accessed through outOpenIndex().
