Package org.pentaho.di.core.util.serialization

Class StepMetaProps

java.lang.Object

org.pentaho.di.core.util.serialization.StepMetaProps

public class StepMetaProps
extends Object

A slim representation of StepMetaInterface properties, used as a way to leverage alternative serialization strategies (e.g. MetaXmlSerializer

Public methods allow conversion: from(StepMetaInterface) and to(StepMetaInterface)

Internally, the StepMetaProps holds a list of StepMetaProps.PropGroup elements, each corresponding to a MetadataInjection group.

InjectionDeep not yet supported.

Method Summary

Modifier and Type	Method	Description
static StepMetaProps	from(StepMetaInterface stepMeta)	Retuns an instance of this class with stepMeta properties mapped to a list of StepMetaProps.PropGroup
List<Object>	getPropertyValue(String group, String property)
StepMetaInterface	to(StepMetaInterface stepMetaInterface)	Sets the properties of this StepMetaProps on
String	toString()
StepMetaProps	withVariables(org.pentaho.di.core.variables.VariableSpace space)	Allows specifying a variable space to be used when applying property values to a stepMeta.

Method Details

from

public static StepMetaProps from(StepMetaInterface stepMeta)

Retuns an instance of this class with stepMeta properties mapped to a list of StepMetaProps.PropGroup

to

public StepMetaInterface to(StepMetaInterface stepMetaInterface)

Sets the properties of this StepMetaProps on

This method mutates the stepMeta, as opposed to returning a new instance, to match more cleanly to Kettle's StepMetaInterface.loadXML(org.w3c.dom.Node, java.util.List<org.pentaho.di.core.database.DatabaseMeta>, java.util.Map<java.lang.String, org.pentaho.di.core.Counter>) design, which loads props into an instance.

withVariables

public StepMetaProps withVariables(org.pentaho.di.core.variables.VariableSpace space)

Allows specifying a variable space to be used when applying property values to a stepMeta.

toString

public String toString()

Overrides:

toString in class Object

getPropertyValue

public List<Object> getPropertyValue(String group,
 String property)
