Constructor Detail

RowSorter

public RowSorter(int sortedColumnIndex,
                 java.lang.String beanProperty,
                 TableDecorator tableDecorator,
                 boolean ascendingOrder,
                 java.util.Comparator compar)

Initialize a new RowSorter.

Parameters:

sortedColumnIndex - index of the sorted column

beanProperty - name of the property. If pProperty is null column index is used to get a static cell value from the row object

tableDecorator - TableDecorator instance

ascendingOrder - boolean ascending order?

compar - the comparator to use

Method Detail

compare

public final int compare(java.lang.Object object1,
                         java.lang.Object object2)

Compares two objects by first fetching a property from each object and then comparing that value. If there are any errors produced while trying to compare these objects then a RunTimeException will be thrown as any error found here will most likely be a programming error that needs to be quickly addressed (like trying to compare objects that are not comparable, or trying to read a property from a bean that is invalid, etc...)

Specified by:

compare in interface java.util.Comparator

Parameters:

object1 - Object

object2 - Object

Returns:

int

Comparator.compare(Object, Object)

equals

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

Is this Comparator the same as another one?

Specified by:

equals in interface java.util.Comparator

Overrides:

equals in class java.lang.Object

Parameters:

object - Object

Returns:

boolean

See Also:

Comparator.equals(Object)

hashCode

public final int hashCode()

Overrides:

hashCode in class java.lang.Object
