Conditions::Condition Class Reference
#include <condition.h>
Inheritance diagram for Conditions::Condition:
Detailed Description
The base class for conditions. Conditions and Actions are the basic building blocks of world interaction. Conditions are small C++ objects which check whether some condition in the world is true. They are used by several other subsystems, like the quest and dialog system.(C) 2005 Radon Labs GmbH

Member Function Documentation
| Ptr< Condition > Conditions::Condition::CreateConditionFromString | ( | const Util::String & | cmd | ) | [static] |
create a complete condition object from a string
Static method which creates any condition object from a command string of the form:
cmd key0=value0 key1=value1 key2=value2
| Util::Array< Ptr< Condition > > Conditions::Condition::CreateConditionsFromString | ( | const Util::String & | cmd | ) | [static] |
create several conditions from semicolon-separated string
Static method which creates many action from a string of the form accepted by CreateConditionFromString() where several conditions are separated by a semicolon.
| void Conditions::Condition::Assert | ( | ) | [virtual] |
assert correct initialisation
This method asserts that all data required by the conditions actually exists. Override in subclass!
Reimplemented in Conditions::And, Conditions::Not, and Conditions::Or.
| bool Conditions::Condition::Assert | ( | const Ptr< Script::InfoLog > & | infoLog | ) | [virtual] |
like Assert() but adds errors to the info log object instead of closing the application
This method asserts that all data actually required by the conditions exist. In subclasses errors can be added to the info log object and in case of errors false can be returned instead of closing the application.
Override in subclass! (infoLog in this class is ignored; Assert() will be called; returns always true)
Reimplemented in Conditions::And, Conditions::Not, and Conditions::Or.
| void Conditions::Condition::ParseArgs | ( | const Util::CommandLineArgs & | args | ) | [virtual] |
parse arguments from command line args object
This method should initialize the Condition object from a CmdLineArgs object. Override in subclass.
| bool Conditions::Condition::Evaluate | ( | ) | [virtual] |
internal evaluation
This method evaluates whether the condition is true, Negates result if not flag is set.
Reimplemented in Conditions::And, Conditions::Not, and Conditions::Or.
| int Core::RefCounted::GetRefCount | ( | ) | const [inline, inherited] |
get the current refcount
Return the current refcount of the object.
| void Core::RefCounted::AddRef | ( | ) | [inline, inherited] |
increment refcount by one
Increment the refcount of the object.
| void Core::RefCounted::Release | ( | ) | [inline, inherited] |
decrement refcount and destroy object if refcount is zero
Decrement the refcount and destroy object if refcount is zero.
| const Util::String & Core::RefCounted::GetClassName | ( | ) | const [inline, inherited] |
get the class name
Get the class name of the object.
| Util::FourCC Core::RefCounted::GetClassFourCC | ( | ) | const [inline, inherited] |
get the class FourCC code
Get the class FourCC of the object.
| void Core::RefCounted::DumpRefCountingLeaks | ( | ) | [static, inherited] |
dump refcounting leaks, call at end of application (NEBULA3_DEBUG builds only!)
This method should be called as the very last before an application exits.
