                         throws ContinueProcessingException,
                                BreakChainException,
                                Exception

Description copied from class: CriteriaFilter

If the Failure needs to be accompanied with additional reasons then one may use ContinueProcessingException.

For all other major exceptions simply throw an Exception type.

Specified by:

checkCriteria in class CriteriaFilter

Returns:

Throws:

ContinueProcessingException - skipping further record processing

BreakChainException - for explained business logic failed conditions

Exception - for any serious Error

getPattern

public Pattern getPattern()

The Pattern to check against

setPattern

public void setPattern(Pattern pattern)

The Pattern to check against

isPartialMatch

public boolean isPartialMatch()

If true, and the input CONTAINTS the pattern then checkCriteria(Object) will stil return true

Default value:

false

setPartialMatch

public void setPartialMatch(boolean partialMatch)

If true, and the input CONTAINTS the pattern then checkCriteria(Object) will stil return true

Default value:

false
