Package org.pentaho.di.core.bowl

Class DefaultBowl

java.lang.Object
org.pentaho.di.core.bowl.BaseBowl
org.pentaho.di.core.bowl.DefaultBowl
All Implemented Interfaces:
Bowl
public class DefaultBowl extends BaseBowl
This Bowl will access the default local configuration for Kettle. It does not include configuration from any other contexts.

This Bowl is roughly backwards-compatible with pre-Bowl behavior. It will access metastore configuration from a connected Repository if there is one, but otherwise uses all local config.

If available, most code that needs a Bowl should get Bowls for Management from Spoon, and for execution from TransMeta or JobMeta.

    • getMetastore

      public org.pentaho.metastore.api.IMetaStore getMetastore() throws org.pentaho.metastore.api.exceptions.MetaStoreException
      Description copied from interface: Bowl
      Gets a Read-Only Metastore that handles any defaulting required for execution-time handling of metastores, for the Bowl.
      Returns:
      IMetaStore A metastore for execution with the Bowl. Never null.
      Throws:
      org.pentaho.metastore.api.exceptions.MetaStoreException

    • getManager

      public <T> T getManager(Class<T> managerClass) throws KettleException
      Description copied from interface: Bowl
      Gets a Manager for some type of object specifically in the context of this Bowl.

      Since constructing and initializing Managers can be expensive, and instances may share state or have other limitations, callers with a Bowl should use this method in favor of directly using the manager type.

      Specified by:
      getManager in interface Bowl
      Overrides:
      getManager in class BaseBowl
      Returns:
      a manager instance, never null.
      Throws:
      KettleException - for other errors.

      Implementations may include different sets of Variables depending on what is in context for that Bowl.

      Returns:

      public void setMetastoreSupplier(Supplier<org.pentaho.metastore.api.IMetaStore> metastoreSupplier)
