Represents a dynamically implemented object.
This class is primarily intended for wrapping scripting language objects, but could be used for other purposes.
An instance of a DynamicObject can be used to store named properties, and by subclassing hasMethod() and invokeMethod(), you can give your object methods.
| DynamicObject::DynamicObject | ( | ) |
| DynamicObject::DynamicObject | ( | const DynamicObject & | ) |
| bool DynamicObject::hasProperty | ( | const Identifier & | propertyName | ) | const |
Returns true if the object has a property with this name.
Note that if the property is actually a method, this will return false.
| const var & DynamicObject::getProperty | ( | const Identifier & | propertyName | ) | const |
Returns a named property.
This returns var() if no such property exists.
| void DynamicObject::setProperty | ( | const Identifier & | propertyName, |
| const var & | newValue ) |
Sets a named property.
| void DynamicObject::removeProperty | ( | const Identifier & | propertyName | ) |
Removes a named property.
| bool DynamicObject::hasMethod | ( | const Identifier & | methodName | ) | const |
Checks whether this object has a property with the given name that has a value of type NativeFunction.
| var DynamicObject::invokeMethod | ( | Identifier | methodName, |
| const var::NativeFunctionArgs & | args ) |
Invokes a named method on this object.
The default implementation looks up the named property, and if it's a method call, then it invokes it.
| void DynamicObject::setMethod | ( | Identifier | methodName, |
| var::NativeFunction | function ) |
Adds a method to the class.
This is basically the same as calling setProperty (methodName, (var::NativeFunction) myFunction), but helps to avoid accidentally invoking the wrong type of var constructor. It also makes the code easier to read.
| void DynamicObject::clear | ( | ) |
Removes all properties and methods from the object.
|
noexcept |
Returns the NamedValueSet that holds the object's properties.
|
noexcept |
Returns the NamedValueSet that holds the object's properties.
| void DynamicObject::cloneAllProperties | ( | ) |
Calls var::clone() on all the properties that this object contains.
|
virtual |
Returns a clone of this object.
The default implementation of this method just returns a new DynamicObject with a (deep) copy of all of its properties. Subclasses can override this to implement their own custom copy routines.
|
virtual |
Writes this object to a text stream in JSON format.
This method is used by JSON::toString and JSON::writeToStream, and you should never need to call it directly, but it's virtual so that custom object types can stringify themselves appropriately.
