Constructor Detail

PluginConfigComparator

public PluginConfigComparator(Global glob,
                              boolean isAscending)

Parameters:

isAscending - 'true' if you want to use this comparator for increasing (ascending) runlevels, i.e. for startup sequences. 'false' if you want to use it for descending (shutdown) sequences.

Method Detail

compare

public final int compare(java.lang.Object o1,
                         java.lang.Object o2)

Compares its two arguments for order. Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second. Null objects are considered of different type and therefore will throw a runtime exception (ClassCastException).

Specified by:

compare in interface java.util.Comparator

equals

public boolean equals(java.lang.Object obj)

Indicates whether some other object is "equal to" this Comparator.

Specified by:

equals in interface java.util.Comparator

Overrides:

equals in class java.lang.Object
