| ExpOperation |
Copy constructor
Parameters:
| original | Operation to copy |
| inline ExpOperation (const ExpOperation& original, const char* name)
| ExpOperation |
Copy constructor with renaming, to be used for named results
Parameters:

| ExpOperation |
Constructor from components
Parameters:
| oper | Operation code |
| name | Optional name of the operation or result |
| value | Optional integer constant used as function parameter count |
| barrier | True if the operation is an expression barrier on the stack |

| ExpOperation |
Constructor of non-integer operation from components
Parameters:
| oper | Operation code |
| name | Name of the operation or result |
| value | String value of operation |
| barrier | True if the operation is an expression barrier on the stack |
| inline ExpOperation (ExpEvaluator::Opcode oper, const char* name, const char* value, int64_t number, bool barrier)
| ExpOperation |
Constructor from components
Parameters:
| oper | Operation code |
| name | Optional name of the operation or result |
| value | String value of operation |
| number | Integer value |
| barrier | True if the operation is an expression barrier on the stack |
| inline ExpEvaluator::Opcode opcode ()
| opcode |
[const]
Retrieve the code of this operation
Returns: Operation code as declared in the expression evaluator
| inline bool isInteger ()
| isInteger |
[const]
Check if an integer value is stored
Returns: True if an integer value is stored
| inline int64_t number ()
| number |
[const]
Retrieve the number stored in this operation
Returns: Stored number
| inline bool barrier ()
| barrier |
[const]
Check if this operation acts as an evaluator barrier on the stack
Returns: True if an expression should not pop this operation off the stack
| inline unsigned int lineNumber ()
| lineNumber |
[const]
Retrieve the line number where the operation was compiled from
Returns: Line number, zero if unknown
| inline void lineNumber (unsigned int line)
| lineNumber |
Set the line number where the operation was compiled from
Parameters:
| line | Number of the compiled line |
| inline int64_t operator= (int64_t num)
| operator= |
Number assignment operator
Parameters:
| num | Numeric value to assign to the operation |
Returns: Assigned number
Reimplemented from NamedString.
| int64_t valInteger ()
| valInteger |
[const virtual]
Retrieve the numeric value of the operation
Returns: Number contained in operation, zero if not a number
| bool valBoolean ()
| valBoolean |
[const virtual]
Retrieve the boolean value of the operation
Returns: True if the operation is to be interpreted as true value
| const char* typeOf ()
| typeOf |
[const virtual]
Retrieve the name of the type of the value of this operation
Returns: Name of the type of the value
| ExpOperation* clone (const char* name)
| clone |
[const virtual]
Clone and rename method
Parameters:
| name | Name of the cloned operation |
Returns: New operation instance
