public COSObjectKey(COSObject object) 
{
        this( object.getObjectNumber().longValue(), object.getGenerationNumber().longValue() );
}

PDFObjectKey constructor comment.

Parameters:

object - The object that this key will represent.

 public COSObjectKey(long num,
    long gen) 
{
        setNumber(num);
        setGeneration(gen);
}

PDFObjectKey constructor comment.

Parameters:

num - The object number.

gen - The object generation number.

 public boolean equals(Object obj) 
{
        return (obj instanceof COSObjectKey) &&
               ((COSObjectKey)obj).getNumber() == getNumber() &&
               ((COSObjectKey)obj).getGeneration() == getGeneration();
}

{@inheritDoc}

 public long getGeneration() 
{
        return generation;
}

This will get the generation number.

 public long getNumber() 
{
        return number;
}

This will get the objects id.

 public int hashCode() 
{
        return (int)(number + generation);
}

{@inheritDoc}

 public  void setGeneration(long newGeneration) 
{
        generation = newGeneration;
}

This will set the objects generation number.

 public  void setNumber(long newNumber) 
{
        number = newNumber;
}

This will set the objects id.

 public String toString() 
{
        return "" + getNumber() + " " + getGeneration() + " R";
}
