◆ hintOperation()

Operation & TTAProgram::Terminal::hintOperation ( ) const

virtual

Return the operation to which this terminal was originally bound.

NOTE! : Method must not be used for checkin if terminal contains opcode. See. operation().

Method is mainly used for preserving information to which operation port reference is bound, during TPEF -> POM -> TPEF write cycles.

Returns: The operation code to which terminal was originally bound. Null operation if terminal does not contain operation code.

Todo:: This should be probably merged with operation() as "hints" are not really useful, we should make sure the operation of the move is known.

◆ registerFile()

const RegisterFile & TTAProgram::Terminal::registerFile ( ) const

virtual

Returns the register file of the general-purpose register.

Applicable only if the unit of the terminal is an instance of RegisterFile.

Returns: The register file of the general-purpose register.

Exceptions

WrongSubclass if the unit of the terminal is not an instance of RegisterFile.

Reimplemented in TTAProgram::TerminalRegister.

Definition at line 225 of file Terminal.cc.

◆ setIndex()

void TTAProgram::Terminal::setIndex ( int index )

virtual

Change the register of the register file to the given index.

Parameters

index The new register index.

Exceptions

OutOfRange	if index is not smaller than the size of the register file or immediate unit it belongs to.
WrongSubclass	if the terminal is not an instance of TerminalRegister.

Reimplemented in TTAProgram::TerminalRegister.
