ValueBuffer |
executeOperator(java.util.LinkedList<ValueBuffer> args)
Interval UNION returns an interval value that contains all the points that are contained in either of the two interval parameter values.
|
java.lang.String[] |
getArgumentTypeNames()
Interval UNION takes two arguments that are both of the same interval type
|
TypeDeclaration |
getReturnTypeDeclaration()
Gets the full type declaration of the type of the return value.
|
java.lang.String |
getReturnTypeName()
Interval UNION returns the same interval type as its arguments
|
java.lang.String |
getSignature()
Gets the name of the operator implemented by this implementation object
|
boolean |
isDeterministic()
Tells whether the operator is deterministic with respect to the arguments of its invocations.

args
- the argument list. The list must hold as many ValueBuffer objects as there are arguments to the operator, and each ValueBuffer object holds a value for some argument to the operator. ValueBuffer objects on the list must appear in the same order as the operator argument declarations. Implementations have the option, but are not required, to do a check the conformance of the argument list (the argument count, notably) to the operator signature.public java.lang.String[] getArgumentTypeNames()
