string ExtendedInstructionDef::getName ( ) [inline]

Returns the name of this instruction.

00074         return _name;

const vector<StandardTypeDescriptorOrdinal>& ExtendedInstructionDef::getParameterTypes ( ) [inline]

Returns the parameter types of this instruction.

00082         return _parameterTypes;
00083     }

string ExtendedInstructionDef::getSignature ( ) const [inline]

Returns the signature of this instruction.

The signature is always of the form "<name>(<type0>,<type1>,...)", for example "substr(ptr,ptr,int,intr)". The signature is used to identify instructions in an ExtendedInstructionTable, and in assembly language instructions such as "CALL 'substr(ptr,ptr,int,ptr) &0, &1, &2, &3".

00093         return _signature;
00094     }

virtual ExtendedInstruction* ExtendedInstructionDef::createInstruction ( vector< RegisterReference * > const & regs ) [pure virtual]

Creates an instruction of this type which references a particular set of registers.

The registers supplied must be the same number and type as the registers supported by the function.

Implemented in FunctorExtendedInstructionDef< T >.

Referenced by InstructionFactory::createInstruction(), testConvertDecimal(), testConvertDoubleToFloat(), testConvertExactNumberToString(), testConvertFloatToDouble(), testConvertFloatToIntTypes(), testConvertIntTypesToFloat(), and testConvertStringToExactNumber().

string ExtendedInstructionDef::computeSignature ( ) [private]
