Constructor Detail

LOStore

public LOStore(LogicalPlan plan,
               FileSpec outputFileSpec,
               StoreFuncInterface storeFunc,
               String signature)

LOStore

public LOStore(LogicalPlan plan,
               FileSpec outputFileSpec,
               StoreFuncInterface storeFunc,
               String signature,
               boolean disambiguationEnabled)

Method Detail

getOutputSpec

public FileSpec getOutputSpec()

getStoreFunc

public StoreFuncInterface getStoreFunc()

getSchema

public LogicalSchema getSchema()
                        throws FrontendException

Description copied from class: LogicalRelationalOperator

Get the schema for the output of this relational operator. This does not merely return the schema variable. If schema is not yet set, this will attempt to construct it. Therefore it is abstract since each operator will need to construct its schema differently.

Specified by:

getSchema in class LogicalRelationalOperator

Returns:

the schema

Throws:

FrontendException

accept

public void accept(PlanVisitor v)
            throws FrontendException

Description copied from class: Operator

Accept a visitor at this node in the graph.

Specified by:

accept in class Operator

Parameters:

v - Visitor to accept.

Throws:

FrontendException

isEqual

public boolean isEqual(Operator other)
                throws FrontendException

Description copied from class: Operator

This is like a shallow equals comparison. It returns true if two operators have equivalent properties even if they are different objects. Here properties mean equivalent plan and equivalent name.

Specified by:

isEqual in class Operator

Returns:

true if two object have equivalent properties, else false

Throws:

FrontendException

getSortInfo

public SortInfo getSortInfo()

setSortInfo

public void setSortInfo(SortInfo sortInfo)

isTmpStore

public boolean isTmpStore()

setTmpStore

public void setTmpStore(boolean isTmpStore)

setInputSpec

public void setInputSpec(FileSpec in)

getInputSpec

public FileSpec getInputSpec()

getSignature

public String getSignature()

getFileSpec

public FileSpec getFileSpec()
