Method Summary

Modifier and Type	Method and Description
void	execute(TAMERequest request, TAMEResponse response, ValueSet blockLocal, Operation statement) Calls the operation and increments the operation count.
ArgumentType[]	getArgumentTypes() Returns the argument types that this operation expects.
ArgumentType	getReturnType() Returns the return types that this operation return.
boolean	isInternal() Is this an internal operation type? Internal operations are not exposed to the parser.

Method Detail

execute

void execute(TAMERequest request,
             TAMEResponse response,
             ValueSet blockLocal,
             Operation statement)
      throws TAMEInterrupt

Calls the operation and increments the operation count. Also performs a runaway check.

Parameters:

request - the TAME request.

response - the TAME response.

blockLocal - the block local variable bank.

statement - the calling statement (get blocks from this).

Throws:

TAMEInterrupt - if a TAMEInterrupt occurs.

isInternal

boolean isInternal()

Is this an internal operation type? Internal operations are not exposed to the parser.

Returns:

true if so, false if not.

getArgumentTypes

ArgumentType[] getArgumentTypes()

Returns the argument types that this operation expects.

Returns:

the argument types.

getReturnType

ArgumentType getReturnType()

Returns the return types that this operation return.

Returns:

the return type, or null for no return.
