Method Details

getStepInjectionMetadataEntries

public List<StepInjectionMetaEntry> getStepInjectionMetadataEntries()
                                                             throws org.pentaho.di.core.exception.KettleException

Specified by:

getStepInjectionMetadataEntries in interface StepMetaInjectionInterface

Returns:

A list of step injection metadata entries. In case the data type of the entry is NONE (0) you will get at least one entry in the details section. You can use this list to see a description of all the metadata.

Throws:

org.pentaho.di.core.exception.KettleException

injectStepMetadataEntries

public void injectStepMetadataEntries(List<StepInjectionMetaEntry> all)
                               throws org.pentaho.di.core.exception.KettleException

Description copied from interface: StepMetaInjectionInterface

Inject the metadata specified into the step metadata

Specified by:

injectStepMetadataEntries in interface StepMetaInjectionInterface

Parameters:

all - the metadata to inject.

Throws:

org.pentaho.di.core.exception.KettleException

extractStepMetadataEntries

public List<StepInjectionMetaEntry> extractStepMetadataEntries()
                                                        throws org.pentaho.di.core.exception.KettleException

Description copied from interface: StepMetaInjectionInterface

Extracts the step metadata in a standard fashion. Enables unit testing more easily by extracting the step metadata and then doing the re-injection into an empty step.

Specified by:

extractStepMetadataEntries in interface StepMetaInjectionInterface

Returns:

A list of step injection metadata entries in a standard fashion. Includes both the entry and the value for the entry.

Throws:

org.pentaho.di.core.exception.KettleException

getMeta

public JaninoMeta getMeta()
