calculate

public AggregatorInfo calculate(java.lang.String pAggregator,
                       java.lang.String pOperation,
                       java.lang.Double pAggValueSoFar,
                       java.lang.Long pQuantityMatched,
                       java.lang.Double pTargetValue,
                       CommerceItem pItem,
                       java.util.Map pAttributes)
                         throws PricingException

This method will call the correct aggregator based on the given pAggregator parameter. Aggregator specific parameters can be passed in via the pAttributes map.

Parameters:

pAggregator - the name of the aggregator to

pOperation - the operation to invoke on the aggregator

pAggValueSoFar - the aggregated value so far, which may be potentially derived from many calculations from multiple items

pQuantityMatched - the number of items that have contributed to the aggregated value

pTargetValue - a value specified in the condition/offer of a promotion which can be used as a target in relation to the aggregated value. May or may not be relevant to an aggregator

pItem - the item that is currently being evaluated

pAttributes - extra parameters

Returns:

holds amended aggValueSoFar and quantityMatched values

Throws:

PricingException - if an error occurred whilst calculating

getOverriddenProperties

public java.util.Set<java.lang.String> getOverriddenProperties()

Returns a set of the properties that have been overridden by the aggregators.

Returns:

a set of all properties that have been overridden by aggregators

isValidOperation

public boolean isValidOperation(java.lang.String pOperation,
                       java.lang.String pAggregator)

Returns true if the given operation is valid for the given aggregator, false otherwise. Will also return false if the aggregator has not been registered. The total operation for the quantity aggregator is always valid, no matter if the aggregator has been registered or not.

Parameters:

pOperation - the name of the operation to validate

pAggregator - the name of the aggregator to validate

Returns:

true if the aggregator operation is valid, false otherwise

isValidAggregator

public boolean isValidAggregator(java.lang.String pAggregator)

Returns true if the aggregator has been registered, false otherwise. The quantity aggregator is always valid, no matter if it has been registered or not.

Parameters:

pAggregator - the name of the aggregator to validate

Returns:

true if the aggregator is valid, false otherwise

isPropertyAggregator

public boolean isPropertyAggregator(java.lang.String pValue)

Returns true if the given value indicates that it is related to a property aggregator.

Parameters:

pValue - value to check

Returns:

true if it can be determined that the given value relates to a property aggregator, false otherwise

parseValue

public java.lang.Number parseValue(java.lang.String pAggregator,
                          java.lang.String pValue,
                          java.lang.Class<?> pType)
                            throws java.lang.NumberFormatException

Parses a string value and returns a Number representation.

Parameters:

pAggregator - the name of the aggregator

pValue - value to be parsed

pType - class type of pValue

Returns:

parsed value

Throws:

java.lang.NumberFormatException - if pValue could not be parsed

parseToLocalizedValue

public java.lang.String parseToLocalizedValue(java.lang.String pAggregator,
                                     java.lang.String pValue,
                                     java.lang.Class<?> pType)
