java.lang.Object

com.neurosys.etl.common.filters.CriteriaFilter

com.neurosys.etl.common.filters.EqualsCheckFilter

All Implemented Interfaces:

Lookup, Predicate, org.apache.commons.collections.Transformer

public class EqualsCheckFilter
extends CriteriaFilter

Checks if the input Object#equals() operand.
If using CriteriaFilter.transform(Object) and Not equals; it will throw a ContinueProcessingException else return the input if it succeeds in transformation.

Description copied from class: CriteriaFilter

Checks the business logic against which the Predicate will succeed (response as true) or fail (false).
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
