namesDisabled

public static final boolean namesDisabled

gcDisabled

public static final boolean gcDisabled

Flag to indicate whether the system hint garbage collection is enabled or not. As a rule of thumb, it is desirable to enable garbage collection when reading large spreadsheets from a batch process or from the command line, but better to deactivate the feature when reading large spreadsheets within a WAS, as the calls to System.gc() not only garbage collect the junk in JExcelApi, but also in the webservers JVM and can cause significant slowdown GC deactivated using -Dnogc=true on the JVM command line Activated by default or by using -Dnogc=false on the JVM command line
