Interface FeatureStoreTransform

All Superinterfaces:

Cloneable, Persistent

All Known Implementing Classes:

public interface FeatureStoreTransform
extends Persistent, Cloneable

A FeatureStoreTransform provides a mechanism for mapping a source FeatureType to a target FeatureType, allowing to build different views (as in database view) over different feature types even from different stores.

Method Summary

Modifier and Type	Method and Description
void	applyTransform(Feature source, EditableFeature target) Applies this transform between two features, copying the source data to the target feature.
FeatureType	getDefaultFeatureType() Returns the default FeatureType.
String	getDescription()
Object	getDynValue(String name)
FeatureStore	getFeatureStore() Returns the FeatureStore to which this transform belongs.
List<FeatureType>	getFeatureTypes() Returns this FeatureStoreTransform's FeatureType(s)
String	getName()
FeatureType	getSourceFeatureTypeFrom(FeatureType targetFeatureType) Returns the original store FeatureType that replaces targetFeatureType of this FeatureStoreTransform's
boolean	hasDynValue(String name)
boolean	isTransformsOriginalValues() Retruns true if this make changes of any attributes values or false if only FeatureType definitions is changed.
void	setDynValue(String name, Object value)
void	setFeatureStore(FeatureStore featureStore) Sets the FeatureStore to which this transform is applied.
void	setSourceMetadata(DynObject metadata) Sets the original metadata for this transform
void	setUp() This method must perform the necessary actions to set up the transformation.

Method Detail

getDefaultFeatureType

FeatureType getDefaultFeatureType()
                           throws DataException

Returns the default FeatureType.

Returns:

default FeatureType

Throws:

DataException

Returns this FeatureStoreTransform's FeatureType(s)

Returns:

Throws:

DataException

getSourceFeatureTypeFrom

FeatureType getSourceFeatureTypeFrom(FeatureType targetFeatureType)

Returns the original store FeatureType that replaces targetFeatureType of this FeatureStoreTransform's

Returns:

source FeatureType

applyTransform

void applyTransform(Feature source,
                    EditableFeature target)
             throws DataException

Applies this transform between two features, copying the source data to the target feature.

Parameters:

source - feature whose data will be used as source

target - feature in which the source data will be copied

Throws:

DataException

setFeatureStore

void setFeatureStore(FeatureStore featureStore)

Sets the FeatureStore to which this transform is applied.

Parameters:

featureStore - FeatureStore to which this transform is applied.

getFeatureStore

FeatureStore getFeatureStore()

Returns the FeatureStore to which this transform belongs.

Returns:

FeatureStore to which this transform belongs.

isTransformsOriginalValues

boolean isTransformsOriginalValues()

setSourceMetadata

void setSourceMetadata(DynObject metadata)

Sets the original metadata for this transform

Parameters:

metadata -

setDynValue

void setDynValue(String name,
                 Object value)
          throws DynFieldNotFoundException

Throws:

DynFieldNotFoundException

setUp

void setUp()
    throws Exception

This method must perform the necessary actions to set up the transformation. It is called automatically when adding the transformation to the store and when the store is retrieved from the persistence.

Throws:

Exception
