public InjectorMeta()

Method Detail

clone

public Object clone()

Description copied from interface: ITransformMeta

Make an exact copy of this transform, make sure to explicitly copy Collections etc.

Specified by:

clone in interface ITransformMeta

Overrides:

clone in class BaseTransformMeta<Injector,InjectorData>

Returns:

an exact copy of this transform

getFields

public void getFields(IRowMeta inputRowMeta,
                      String name,
                      IRowMeta[] info,
                      TransformMeta nextTransform,
                      IVariables variables,
                      IHopMetadataProvider metadataProvider)
               throws HopTransformException

Description copied from class: BaseTransformMeta

Gets the fields. This method doesn't pass along any pipeline metadata to help resolve output row metadata.

Specified by:

getFields in interface ITransformMeta

Overrides:

getFields in class BaseTransformMeta<Injector,InjectorData>

Parameters:

inputRowMeta - the input row meta that is modified in this method to reflect the output row metadata of the transform

name - Name of the transform to use as input for the origin field in the values

info - Fields used as extra lookup information

nextTransform - the next transform that is targeted

variables - the variables The variable variables to use to replace variables

metadataProvider - the MetaStore to use to load additional external data or metadata impacting the output fields

Throws:

HopTransformException - the hop transform exception

check

public void check(List<ICheckResult> remarks,
                  PipelineMeta pipelineMeta,
                  TransformMeta transformMeta,
                  IRowMeta prev,
                  String[] input,
                  String[] output,
                  IRowMeta info,
                  IVariables variables,
                  IHopMetadataProvider metadataProvider)

Description copied from interface: ITransformMeta

Checks the settings of this transform and puts the findings in a remarks List.

Specified by:

check in interface ITransformMeta

Overrides:

check in class BaseTransformMeta<Injector,InjectorData>

Parameters:

remarks - The list to put the remarks in @see org.apache.hop.core.CheckResult

transformMeta - The transformMeta to help checking

prev - The fields coming from the previous transform

input - The input transform names

output - The output transform names

info - The fields that are used as information by the transform

variables - the variable variables to resolve variable expressions with

metadataProvider - the MetaStore to use to load additional external data or metadata impacting the output fields

getInjectorFields

public List<InjectorField> getInjectorFields()

Gets injectorFields

Returns:

value of injectorFields

setInjectorFields

public void setInjectorFields(List<InjectorField> injectorFields)

Parameters:

injectorFields - The injectorFields to set
