You are here: Filters > ChangeDetector


Detects changes between two sets of input features.

This transformer is often used with multiple readers, to identify changed features in the two files. It can identify all features that two input files have in common, and those which are in one file and not the other, such as the additions and the deletions.

The ChangeDetector may require a significant amount of processing time, depending on the number of features and/or attributes. Alternatively, consider using the CRCCalculator to calculate a CRC value for each feature, then perform a match only on the CRC value attribute.

The Matcher provides a more general approach, which may be more convenient for certain applications.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter.
