Class Inheritance
Imports
java.io.PrintStream, java.util.ArrayList, .Arrays, .Collection, .Collections, .HashMap, .Map.Entry
Instructions on how to use the NativeStats tool with a standalone SWT example:
  1. Compile the native libraries defining the NATIVE_STATS flag.
  2. Add the following code around the sections of interest to dump the native calls done in that section. 
         StatsInterface si = MyFooStatsInterface.INSTANCE;
     NativeStats stats = new NativeStats(si); 
     ... // your code
     stats.diff().dump(System.out);
  3. Or add the following code at a given point to dump a snapshot of the native calls done until that point. 
         stats.snapshot().dump(System.out);

Method Detail

public int compareTo(NativeStats.NativeFunction func)

Implements java.lang.Comparable.compareTo.

Doc from java.lang.Comparable.compareTo.

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

The implementor must ensure signum(x.compareTo(y)) == -signum(y.compareTo(x)) for all x and y. (This implies that x.compareTo(y) must throw an exception if and only if y.compareTo(x) throws an exception.)

The implementor must also ensure that the relation is transitive: (x.compareTo(y) > 0 && y.compareTo(z) > 0) implies x.compareTo(z) > 0.

Finally, the implementor must ensure that x.compareTo(y)==0 implies that signum(x.compareTo(z)) == signum(y.compareTo(z)), for all z.

Parameters
func:NativeStats.NativeFunction

the object to be compared.

Returns:int

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.
