getOutputs
public List<LogicalOperator> getOutputs()
setOutputs
public void setOutputs(ArrayList<LogicalOperator> outputs)
addOutput
public void addOutput(LogicalOperator lOp)
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

- Throws:
FrontendException
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.

supportsMultipleOutputs
in class LogicalOperator
- Returns:
- true if it does, otherwise false.
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.
getType
public byte getType()
- Description copied from class:
LogicalOperator
- Get the type of this operator.

clone
protected Object clone()
throws CloneNotSupportedException
- Overrides:
clone
in class LogicalOperator
- Throws:
CloneNotSupportedException
