Interface NDSPostProcessorInterface

public interface NDSPostProcessorInterface

This interface supports user generated processing modules that can be sequentially chained thru the use of the NDS parameter processModules. There are a number of predefined modules. These include DataPivot, DataTranspose, DataGroup, DataFilter, and DataAggregate. This interface allows Developers to write custom data manipulation functions that then can be integrated into any Named Data Set (NDS). Developers using this interface should put the resultant class file(s) in the root/classes directory and reference the class in the NDS file using the complete classpath, e.g.: processModules: DataTranspose, com.yourcompany.YourProcess, DataAggregate

Method Summary

java.lang.Object[][]

processNDS(java.lang.Object[][] data, java.util.Hashtable parameters, int nth) Constructs a local toolkit with security credentials.

Method Detail

processNDS

public java.lang.Object[][] processNDS(java.lang.Object[][] data,
                                       java.util.Hashtable parameters,
                                       int nth)

Constructs a local toolkit with security credentials.

Parameters:

data - Two dimensional object array of input data.

parameters - The parameter hashtable will contain ALL parameters that were defined in the NDS template.

nth - Normally "1". If multiple instances of a given data processor are used in the same processModules chain, the "nth" key can be used to help distinguish which parameters should be attributed to which instance.

Returns:

output data object array
