#include <cdynamicexpression.h>
Description
Interface for extending cDynamicExpression with support for variables, member access, (extra) function calls, and method calls. If a variable/member/etc was not found, the corresponding method should return cValue(), i.e. the "undefined" value.

Member Function Documentation
◆ dup()
|
pure virtual |
Create and return an exact copy of this object.
Implemented in cDynamicExpression::SymbolTable.
◆ readVariable() [1/2]
Return the value of a variable with the given name.
Reimplemented in cDynamicExpression::SymbolTable.
◆ readVariable() [2/2]
Return the value of an element of an array variable with the given name. Expression syntax: name[index]
Reimplemented in cDynamicExpression::SymbolTable.
◆ readMember() [1/2]
|
inlinevirtual |
Return the value of a member of the given object. Expression syntax: object.name
◆ readMember() [2/2]
|
inlinevirtual |
Return the value of an element of an array member of the given object. Expression syntax: object.name[index]
◆ callFunction()
|
inlinevirtual |
Evaluate a function call with the given arguments. Expression syntax: name(argv0, argv1,...)
◆ callMethod()
|
inlinevirtual |
Evaluate a method call on the given object with the given arguments. Expression syntax: object.name(argv0, argv1,...)
