Document

Returns a hash code based on the "deep contents" of the specified array.

Usage

From source file:org.apache.hadoop.mapreduce.counters.FrameworkCounterGroup.java

@Override
public synchronized int hashCode() {
    // need to be deep as counters is an array
    return Arrays.deepHashCode(new Object[] { enumClass, counters, displayName });
}
