Constructor Detail

ComparableByteArray

public ComparableByteArray(byte[] array)

Creates a comparable byte array object.

Parameters:

array - The content array of this object.

Preconditions:

(array <> null)

Method Detail

equals

public static boolean equals(byte[] a1,
                             byte[] a2)

Compare both byte arrays. Both arrays are considered equal if both have the same length and contain the same values, or if both arrays are null.

Parameters:

a1 - The first array.

a2 - The second array.

Returns:

true if both are equal.

equals

public boolean equals(java.lang.Object otherObject)

Checks, if the content array of this object is equal to the content array of the other object.

Overrides:

equals in class java.lang.Object

Parameters:

otherObject - The other comparable byte array object.

Returns:

True, if the array of this object contains the same bytes as the content array of the other object; false, otherwise.

getArray

public byte[] getArray()

Get the content byte array of this object.

Returns:

The byte array that is the content of this object.

Postconditions:

(result <> null)

hashCode

public int hashCode()

A hash code of this object. Derived from the content byte array.

Overrides:

hashCode in class java.lang.Object

Returns:

A hash code specific for this object.

compareTo

public int compareTo(java.lang.Object otherObject)

Implementation of Comparable.compareTo(java.lang.Object).

Specified by:

compareTo in interface java.lang.Comparable

Parameters:

otherObject - The other ComparableByteArray object to compare to.

Returns:

A value < 0, if this array is lexicographically less than the other array; a value > 0, if this array is lexicographically greater than the other array; or 0, if both array have the same length and the same content.

Preconditions:

(otherObject instanceof ComparableByteArray)
