Constructor Detail

AbstractTestSemantics

public AbstractTestSemantics()

Method Detail

compareTo

public final int compareTo(Test o)

Define ordering.

Specified by:

compareTo in interface java.lang.Comparable<Test>

Parameters:

o - Object to compare.

Returns:

-1 if o is less, 0 if its equal, 1 if its greater.

hashCode

public final int hashCode()

Define hash semantics. The test number is used as the hash code. I wondered whether it was worth distributing the hash codes more evenly across the range of an int, but using the value is good enough for java.lang.Integer so its good enough for us.

Overrides:

hashCode in class java.lang.Object

Returns:

The hash code.

equals

public final boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

toString

public final java.lang.String toString()

Overrides:

toString in class java.lang.Object
