uk.gov.gchq.gaffer.spark.operation.scalardd.GetRDDOfElements

All Implemented Interfaces:

Closeable, AutoCloseable, GraphFilters, OperationView, SeededGraphFilters, Input<Iterable<? extends ElementId>>, InputOutput<Iterable<? extends ElementId>,org.apache.spark.rdd.RDD<Element>>, MultiElementIdInput, MultiInput<ElementId>, Output<org.apache.spark.rdd.RDD<Element>>, Operation

public class GetRDDOfElements
extends Object
implements InputOutput<Iterable<? extends ElementId>,org.apache.spark.rdd.RDD<Element>>, MultiElementIdInput, SeededGraphFilters

A GetRDDOfElements operation retrieves all the Elements for the input seeds from the target store, and returns them inside a RDD.

GetRDDOfElements

public GetRDDOfElements()

Method Detail

getOptions

public Map<String,String> getOptions()

Specified by:

getOptions in interface Operation

Returns:

the operation options. This may contain store specific options such as authorisation strings or and other properties required for the operation to be executed. Note these options will probably not be interpreted in the same way by every store implementation.

setOptions

public void setOptions(Map<String,String> options)

Specified by:

setOptions in interface Operation

Parameters:

options - the operation options. This may contain store specific options such as authorisation strings or and other properties required for the operation to be executed. Note these options will probably not be interpreted in the same way by every store implementation.

getOutputTypeReference

public com.fasterxml.jackson.core.type.TypeReference<org.apache.spark.rdd.RDD<Element>> getOutputTypeReference()

Specified by:

getOutputTypeReference in interface Output<org.apache.spark.rdd.RDD<Element>>

getInput

public Iterable<? extends ElementId> getInput()

Specified by:

getInput in interface Input<Iterable<? extends ElementId>>

Specified by:

getInput in interface MultiInput<ElementId>

setInput

public void setInput(Iterable<? extends ElementId> input)

Specified by:

setInput in interface Input<Iterable<? extends ElementId>>

Specified by:

setInput in interface MultiInput<ElementId>

getIncludeIncomingOutGoing

public SeededGraphFilters.IncludeIncomingOutgoingType getIncludeIncomingOutGoing()

Specified by:

getIncludeIncomingOutGoing in interface SeededGraphFilters

Returns:

includeIncomingOutGoing a SeededGraphFilters.IncludeIncomingOutgoingType that controls the incoming/outgoing direction of Edges that are filtered out in the operation.

See Also:

SeededGraphFilters.IncludeIncomingOutgoingType

setIncludeIncomingOutGoing

public void setIncludeIncomingOutGoing(SeededGraphFilters.IncludeIncomingOutgoingType inOutType)

Specified by:

setIncludeIncomingOutGoing in interface SeededGraphFilters

Parameters:

inOutType - a SeededGraphFilters.IncludeIncomingOutgoingType that controls the incoming/outgoing direction of Edges that are filtered out in the operation.

See Also:

SeededGraphFilters.IncludeIncomingOutgoingType

getView

public View getView()

Specified by:

getView in interface OperationView

Returns:

the View for the operation.

See Also:

View

setView

public void setView(View view)

Specified by:

setView in interface OperationView

Parameters:

view - the View for the operation.

See Also:

View

getDirectedType

public DirectedType getDirectedType()

Specified by:

getDirectedType in interface GraphFilters

setDirectedType

public void setDirectedType(DirectedType directedType)

Specified by:

setDirectedType in interface GraphFilters

shallowClone

public GetRDDOfElements shallowClone()

Description copied from interface: Operation

Operation implementations should ensure a ShallowClone method is implemented. Performs a shallow clone. Creates a new instance and copies the fields across. It does not clone the fields. If the operation contains nested operations, these must also be cloned.

Specified by:

shallowClone in interface Operation

Returns:

shallow clone
