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);
