compareTo

public int compareTo(Object valueToCompare,
 Object compareTo)
              throws CantCompareException

Description copied from interface: ObjectConverter

Compare two elements.

If required, try to convert the elementToCompare so it can be compared with compareTo. It is also possible that we have to convert compareTo, for the comparison to be possible. For example, if compareTo is Long(10) and elementToCompare is BigDecimal(12.34), we have to convert both elements to BigDecimal so they can be compared.

For a comparison to work, the two elements must be (after conversion or not) of the same type and this type must implement Comparable.

Specified by:

compareTo in interface ObjectConverter

Throws:

CantCompareException - if the elements can't be compared together.

isEquivalent

public boolean isEquivalent(Object valueToCompare,
 Object compareTo)

Description copied from interface: ObjectConverter

Are the two elements equivalent?

If required, try to convert the elementToCompare so it can be compared with compareTo. It is also possible that we have to convert compareTo, for the comparison to be possible. For example, if compareTo is Long(10) and elementToCompare is BigDecimal(12.34), we have to convert both elements to BigDecimal so they can be compared.

For the two elements to be equivalent, they must be (after conversion or not) of the same type and then the Object.equals(Object) method must return true.

Specified by:

isEquivalent in interface ObjectConverter

isAtLeastOneEquivalentElementInCommon

public boolean isAtLeastOneEquivalentElementInCommon(Collection<?> col1,
 Collection<?> col2)

Description copied from interface: ObjectConverter

Do the two Collections have at least one equivalent element in common?
