storeMetadata

storeMetadata

Stores Java transformation metadata that you can retrieve at runtime with the getMetadata method.
Use the following syntax:
storeMetadata (String key String data);
The following table describes the parameters:
Parameter
Parameter Type
Datatype
Description
key
Input
String
Identifies the metadata. The storeMetadata method requires a key to identify the metadata. Define the key as any string.
data
Input
String
The data that you want to store as Java transformation metadata.
You can add the storeMetadata method to the Java code to the following code entry tabs:
  • Helper
  • On Input
  • At End
  • Optimizer Interfaces
  • Functions
You can configure the storeMetadata method in an active transformation to accept filter conditions for push-into optimization. The storeMetadata method stores a filter condition that the optimizer pushes from the mapping to the Java transformation.
// Store a filter condition storeMetadata ("FilterKey", condition);
