-
public class BigDecimalMin
- extends AbstractBigDecimalAggregator
Calculates a minimum of numeric values extracted from a set of entries in a Map in a form of a BigDecimal
value. All the extracted objects will be treated as BigDecimal
, BigInteger
or Java double values. If the set of entries is empty, a null result is returned.

BigDecimalMin
public BigDecimalMin()
- Default constructor (necessary for the ExternalizableLite interface).
BigDecimalMin
public BigDecimalMin(ValueExtractor extractor)
- Construct a BigDecimalMin aggregator.
- Parameters:
extractor
- the extractor that provides a value in the form of any Java object that is a Number
BigDecimalMin
public BigDecimalMin(String sMethod)
- Construct a BigDecimalMin aggregator.
- Parameters:
sMethod
- the name of the method that returns a value in the form of any Java object that is a Number
process
protected void process(Object o,
boolean fFinal)
- Incorporate one aggregatable value into the result. <p/> If the fFinal parameter is true, the given object is a partial result (returned by an individual parallel aggregator) that should be incorporated into the final result; otherwise, the object is a value extracted from an
InvocableMap.Entry
.
-
- Specified by:
process
in class AbstractAggregator
-
- Parameters:
o
- the value to incorporate into the aggregated result
fFinal
- true to indicate that the given object is a partial result returned by a parallel aggregator
