Methods

Modifier and Type	Method and Description
protected boolean	matchBetween(OwSearchCriteria filter, Date value) Between value compare, where both limits must be include for comparison. Neither the minimum limit nor the maximum limit should be excluded.
protected boolean	matchEquals(OwSearchCriteria filter, Date value) Value and filter value must be equal! But equal operation is depending on the type and restriction of the given value.
protected boolean	matchGreater(OwSearchCriteria filter, Date value) Value restriction where it must be greater as the filter.
protected boolean	matchGreaterEquals(OwSearchCriteria filter, Date value) Greater or equals compare of given value and filter.
protected boolean	matchLess(OwSearchCriteria filter, Date value) Value must be less than the defined filter.
protected boolean	matchLessEquals(OwSearchCriteria filter, Date value) Less or equals compare of the value and filter.
protected boolean	matchLike(OwSearchCriteria filter, Date value) A like compare of the value, the filter criteria can be used to get the representation of wildcard characters.

Method Detail

matchBetween

protected boolean matchBetween(OwSearchCriteria filter,
                   Date value)

Description copied from class: OwAbstractComparator

Between value compare, where both limits must be include for comparison. Neither the minimum limit nor the maximum limit should be excluded.

Specified by:

matchBetween in class OwAbstractComparator<Date>

Parameters:

filter - OwSearchCriteria providing the limit(s)

value - T to match with criteria

Returns:

boolean if matches criteria

matchLessEquals

protected boolean matchLessEquals(OwSearchCriteria filter,
                      Date value)

Description copied from class: OwAbstractComparator

Less or equals compare of the value and filter.

Specified by:

matchLessEquals in class OwAbstractComparator<Date>

Parameters:

filter - OwSearchCriteria to restrict value

value - T to match against filter

Returns:

boolean if matches criteria

matchGreaterEquals

protected boolean matchGreaterEquals(OwSearchCriteria filter,
                         Date value)

Description copied from class: OwAbstractComparator

Greater or equals compare of given value and filter.

Specified by:

matchGreaterEquals in class OwAbstractComparator<Date>

Parameters:

filter - OwSearchCriteria to restrict value

value - T to match against filter

Returns:

boolean if matches criteria

matchLess

protected boolean matchLess(OwSearchCriteria filter,
                Date value)

Description copied from class: OwAbstractComparator

Value must be less than the defined filter.

Specified by:

matchLess in class OwAbstractComparator<Date>

Parameters:

filter - OwSearchCriteria to restrict value

value - T to match against filter

Returns:

boolean if matches criteria

matchGreater

protected boolean matchGreater(OwSearchCriteria filter,
                   Date value)

Description copied from class: OwAbstractComparator

Value restriction where it must be greater as the filter.

Specified by:

matchGreater in class OwAbstractComparator<Date>

Parameters:

filter - OwSearchCriteria to restrict value

value - T to match against filter

Returns:

boolean if matches criteria

matchLike

protected boolean matchLike(OwSearchCriteria filter,
                Date value)

Description copied from class: OwAbstractComparator

A like compare of the value, the filter criteria can be used to get the representation of wildcard characters.

Specified by:

matchLike in class OwAbstractComparator<Date>

Parameters:

filter - OwSearchCriteria to restrict value

value - T to match against filter

Returns:

boolean if matches criteria

matchEquals

protected boolean matchEquals(OwSearchCriteria filter,
                  Date value)

Description copied from class: OwAbstractComparator

Value and filter value must be equal! But equal operation is depending on the type and restriction of the given value.

For special cases (Date, Number,...) an equal compare will still return true even if the filter and given value not match fully each other .

Specified by:

matchEquals in class OwAbstractComparator<Date>

Parameters:

filter - OwSearchCriteria to restrict value

value - T to match against filter

Returns:

boolean if matches criteria
