Description
Fields
|
myOperation: TOpcode; |
|
Refers to the operator encountered, if any | |
Methods
|
function parse: int64; override; |
|
Parse the expression. This method simply constructs an instance of ALinearCExpression and calls ALinearCExpression.parse on it. | |
|
function performOperation: int64; virtual; |
|
Perform the operation indicated by the ALinearCCompoundExpression.operation. This method is called by ALinearCCompoundExpression.parse after two subexpressions, separated by an operator, have been parsed. ReturnsThe total number of errors that occurred while attempting to perform the operation. A value of zero (0) indicates success. | |
|
function operation: TOpcode; |
|
Retrieve the operator encountered while parsing the compound expression, if any. Although a compound expression will generally consist of two or more subexpressions, separated by an operator, this is not required. It is perfectly valid for a compound expression to consist of a single subexpression with no operators, in which case this method will return zero (0). | |
