Method Detail

executeOperator

public ValueBuffer executeOperator(java.util.LinkedList<ValueBuffer> args)
ENDSWITH operator returns a truth-value indicating whether the first argument's ending sequence of tokens is identical to the second argument's complete sequence of tokens.

Specified by:
executeOperator in interface OperatorImplementation
Parameters:
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.
Returns:
A ValueBuffer object holding the result value of the operator execution in internal format.

getArgumentTypeNames

public java.lang.String[] getArgumentTypeNames()
ENDSWITH takes two arguments, both of type NAME

Specified by:
getArgumentTypeNames in interface OperatorImplementation
Returns:
The names of the argument types

getReturnTypeName

public java.lang.String getReturnTypeName()
ENDSWITH returns a BOOLEAN

Specified by:
getReturnTypeName in interface OperatorImplementation
Returns:
the name of the type of the return value

isDeterministic

public boolean isDeterministic()
Description copied from interface: OperatorImplementation_V0104
Tells whether the operator is deterministic with respect to the arguments of its invocations. An operator is deterministic if and only if for any two distinct invocations, if all the argument values are the same, then the result value returned will also be the same. An example of a nondeterministic operators is RANDOM().

Specified by:
isDeterministic in interface OperatorImplementation_V0104
Returns:
true if the operator is deterministic.
