## Detailed Description

defines a Qore-language class

Qore's classes can be either implemented by Qore language code (user classes) or in C++ (builtin classes), or both, as in the case of a builtin class that also has user methods.

## Member Function Documentation

## addBaseClass()

DLLEXPORT void QoreClass::addBaseClass | ( | QoreClass * | qc,
|  | bool | virt = `false`
| ) |  |

Adds a base class to the current class.

Parameters

  qc | the class to add
  virt | if the base class is "virtual", meaning that the current class's binary object is also compatible with this base class's data (meaning that the base class's private data object is also a base class of this class's private data object)

## addBuiltinBaseClass()

DLLEXPORT void QoreClass::addBuiltinBaseClass | ( | QoreClass * | qc | ) |

make a builtin class a child of another builtin class

the xargs argument must not be used; before qore supported function overloading, base class arguments could be given here

Parameters

  qc | the base class to add

## addBuiltinConstant()

DLLEXPORT void QoreClass::addBuiltinConstant | ( | const char * | name,
|  | QoreValue | value,
|  | ClassAccess | access = `Public`,
|  | const QoreTypeInfo * | typeInfo = `nullptr`
| ) |  |

adds a class constant to the class

Parameters

  name | the name of the constant; cannot be the same as the name of a static variable
  value | the value of the constant
  access | the access protection of the constant
  typeInfo | only need to set if the value assigned to the constant is not an internally-defined type and therefore the type info cannot be automatically determined, otherwise this parameter may be passed as NULL, in which case the type info will be automatically determined

## addBuiltinStaticVar()

DLLEXPORT void QoreClass::addBuiltinStaticVar | ( | const char * | name,
|  | QoreValue | value,
|  | ClassAccess | access = `Public`,
|  | const QoreTypeInfo * | typeInfo = `nullptr`
| ) |  |

adds a static variable to the class

Parameters

  name | the name of the static variable; cannot be the same as the name of a class constant
  value | the initial of the static variable
  access | the access protection of the static variable
  typeInfo | only need to set if the initial value assigned to the static variable (as given by the 'value' parameter) is not an internally-defined type and therefore the type info cannot be automatically determined, otherwise this parameter may be passed as NULL, in which case the type info will be automatically determined

## addBuiltinVirtualBaseClass()

DLLEXPORT void QoreClass::addBuiltinVirtualBaseClass | ( | QoreClass * | qc | ) |

sets "virtual" base class for a class, meaning that the base class data is appropriate for use in the subclass builtin methods

this method adds a base class placeholder for a subclass - where the subclass's private data object is actually a subclass of the parent class and all methods are virtual, so the base class's constructor, destructor, and copy constructor will never be run and the base class methods will be passed a pointer to the subclass's data

Parameters

  qc | the base class to add

## addConstructor()

DLLEXPORT void QoreClass::addConstructor | ( | const void * | ptr,
|  | q_external_constructor_t | meth,
|  | ClassAccess | access = `Public`,
|  | int64 | n_flags = `QCF_NO_FLAGS`,
|  | int64 | n_domain = `QDOM_DEFAULT`,
|  | const type_vec_t & | n_typeList = `type_vec_t()`,
|  | const arg_vec_t & | defaultArgList = `arg_vec_t()`,
|  | const name_vec_t & | n_names = `name_vec_t()`
| ) |  |

adds a constructor method variant with the external calling convention and includes the access specifier, additional functional domain info, and parameter type info

Since
  Qore 0.9

## addDefaultBuiltinBaseClass()

DLLEXPORT void QoreClass::addDefaultBuiltinBaseClass | ( | QoreClass * | qc | ) |

make a builtin class a child of another builtin class and ensures that the given class's private data will be used in all class methods

In the case this function is used, this objects of class cannot have private data saved against the class ID. The xargs argument must not be used; before qore supported function overloading, base class arguments could be given here

Parameters

  qc | the base class to add

## addMethod() [1/2]

DLLEXPORT void QoreClass::addMethod | ( | const char * | n_name,
|  | q_method_n_t | meth,
|  | ClassAccess | access = `Public`,
|  | int64 | n_flags = `QCF_NO_FLAGS`,
|  | int64 | n_domain = `QDOM_DEFAULT`,
|  | const QoreTypeInfo * | returnTypeInfo = `0`,
|  | unsigned | num_params = `0`,
|  |  | ...
| ) |  |

adds a builtin method variant to a class

Example:
  // the actual function can be declared with the class to be expected as the private data as follows:
  static QoreValue AL_lock(QoreObject* self, QoreAutoLock* m, const QoreListNode* args, q_rt_flags_t rtflag, ExceptionSink* xsink);
  ...
  // and then casted to (q_method_t) in the addMethod call:
  QC_AutoLock->addMethod("lock", (q_method_n_t)AL_lock, Public, QCF_NO_FLAGS, QDOM_DEFAULT, nothingTypeInfo);

in debuggging mode, the call will abort if the name of the method is "constructor", "destructor", or "copy", or if the method already exists in the class. To set the constructor method, call QoreClass::setConstructor(). To set the destructor method, call QoreClass::setDestructor(). To set the copy method, call QoreClass::setCopy().

  meth | the method to be added
  access | the access modifier for the method variant
  n_flags | code flags
  n_domain | functional domain
