LOSplitOutput
public LOSplitOutput(LogicalPlan plan,
OperatorKey key,
int index,
LogicalPlan condPlan)
- Parameters:
plan
- LogicalPlan this operator is a part of.key
- OperatorKey for this operatorindex
- index of this output in the splitcondPlan
- logical plan containing the condition for this split output
getConditionPlan
public LogicalPlan getConditionPlan()
name
public String name()
- Specified by:
name
in class Operator<LOVisitor>
getSchema
public Schema getSchema()
throws FrontendException
- Description copied from class:
LogicalOperator
- Get a copy of the schema for the output of this operator.
- Specified by:
getSchema
in class LogicalOperator
- Throws:
FrontendException
visit
public void visit(LOVisitor v)
throws VisitorException
- Description copied from class:
LogicalOperator
- Visit this node with the provided visitor. This should only be called by
the visitor class itself, never directly.
- Specified by:
visit
in class LogicalOperator
- Parameters:
v
- Visitor to visit with.
- Throws:
VisitorException
- if the visitor has a problem.
supportsMultipleInputs
public boolean supportsMultipleInputs()
- Description copied from class:
Operator
- Indicates whether this operator supports multiple inputs.
- Specified by:
supportsMultipleInputs
in class Operator<LOVisitor>
- Returns:
- true if it does, otherwise false.
getReadFrom
public int getReadFrom()
getType
public byte getType()
- Description copied from class:
LogicalOperator
- Get the type of this operator.
- Overrides:
getType
in class LogicalOperator
unsetSchema
public void unsetSchema()
throws VisitorException
- Description copied from class:
LogicalOperator
- Unset the schema as if it had not been calculated. This is used by
anyone who reorganizes the tree and needs to have schemas recalculated.
- Overrides:
unsetSchema
in class LogicalOperator
- Throws:
VisitorException
clone
protected Object clone()
throws CloneNotSupportedException
- Overrides:
clone
in class LogicalOperator
- Throws:
CloneNotSupportedException
- See Also:
Do not use the clone method directly. Operators are cloned when logical plans
are cloned using {@link LogicalPlanCloner}
