Kettle learn from. ktr Files generating Transmeta objects

https://github.com/pentaho/pdi-sdk-plugins/blob/master/kettle-sdk-embedding-samples/src/org/pentaho/di/sdk/ Samples/embedding/runningtransformations.java

1, after the conversion is designed in the Di designer, the transformation is persisted to the local disk as a. ktr file. and Kettle provides a method call to parse the Transmeta object from the. ktr file. The Transmeta object is a Java object that characterizes the transformation run.

2, it is very simple to parse the Transmeta object from the. ktr file, first to initialize the running environment. Otherwise, a run-time error will be reported for a Dbcache class. Objects of this class are used when creating Transmeta objects.

Try {            kettleenvironment.init ();         Catch (kettleexception e) {            e.printstacktrace ();             return ;        }
Transmeta = new Transmeta (KTR, (Repository) null);
