Emmanuel Lecharny commented on DIRSTUDIO-1200:
----------------------------------------------
It should be easy to fix the {{AttributeComparator.compare}} method. The
problem is in the two tests {{if ( value1 != null && value2 != null )}} and
{{if ( attribute1 != null && attribute2 != null )}}.
Something like that could work :
{code:java}
private IValue getValue( Object element )
{
if ( element instanceof IValue )
{
return ( IValue ) element;
}
else if ( element instanceof LdifAttrValLine )
{
return ModelConverter.ldifAttrValLineToValue( ( LdifAttrValLine )
element, dummyEntry );
}
else
{
return null;
}
}
private IAttribute getAttribute( Object element )
{
if ( element instanceof IAttribute )
{
return ( IAttribute ) element;
}
else if ( element instanceof IValue )
{
return ( ( IValue ) element ).getAttribute();
}
else if ( element instanceof LdifAttrValLine )
{
LdifAttrValLine line1 = ( LdifAttrValLine ) element;
IValue value = ModelConverter.ldifAttrValLineToValue( line1,
dummyEntry );
return value.getAttribute();
}
else
{
return null;
}
}
private int compare( IValue value1, IValue value2 )
{
if ( this.getSortByOrDefault() ==
BrowserCoreConstants.SORT_BY_ATTRIBUTE_DESCRIPTION )
{
if ( value1.getAttribute() != value2.getAttribute() )
{
return this.compareAttributeNames( value1.getAttribute(),
value2.getAttribute() );
}
else
{
return this.compareValues( value1, value2 );
}
}
else if ( this.getSortByOrDefault() ==
BrowserCoreConstants.SORT_BY_VALUE )
{
return this.compareValues( value1, value2 );
}
else
{
return this.equal();
}
}
@Override
public int compare( Object o1, Object o2 )
{
IAttribute attribute1 = getAttribute( o1 );
IValue value1 = getValue( o1);
IAttribute attribute2 = getAttribute( o2 );
IValue value2 = getValue( o2 );
if ( value1 != null )
{
if ( value2 == null )
{
return greaterThan();
}
else
{
return compare( value1, value2 );
}
}
else if ( value2 != null )
{
return lessThan();
}
if ( attribute1 != null )
{
if ( attribute2 == null )
{
return greaterThan();
}
else
{
return compareAttributeNames( attribute1, attribute2 );
}
}
else if ( attribute2 != null )
{
return lessThan();
}
else
{
return equal();
}
}
