java.lang.Object
- simple.FilterEcho

```
public class FilterEcho
extends java.lang.Object
```
Sample filtering echo topology application. This Java application builds a simple topology that echos its command line arguments to standard output.
The application implements the typical pattern of code that declares a topology followed by submission of the topology to a Streams context com.ibm.streamsx.topology.context.StreamsContext.
This demonstrates use of Java functional logic to filter the tuples. An in-line anonymous class implements the filtering logic, in this case only echo tuples that start with the letter d.
This topology is always executed in embedded mode, within this JVM.
This may be executed from the samples/java/functional directory as:
- ant run.filterecho - Using Apache Ant, this will run in embedded mode.
- java -cp functionalsamples.jar:../../../com.ibm.streamsx.topology/lib/com.ibm.streamsx.topology.jar:$STREAMS_INSTALL/lib/com.ibm.streams.operator.samples.jar simple.FilterEcho "d print this" "omit this" - Run directly from the command line in embedded mode.
- An application execution within your IDE once you set the class path to include the correct jars.
