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.

should be only called under the appropriate lock (ex: program parse lock while parsing)

Member Function Documentation

◆ addBaseClass()

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

Adds a base class to the current class.

Parameters
qcthe class to add
virtif 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
qcthe 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
namethe name of the constant; cannot be the same as the name of a static variable
valuethe value of the constant
accessthe access protection of the constant
typeInfoonly 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
namethe name of the static variable; cannot be the same as the name of a class constant
valuethe initial of the static variable
accessthe access protection of the static variable
typeInfoonly 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
qcthe 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, objects of this class cannot have private data saved against the class ID.

Parameters
qcthe base class to add

◆ addMethod() [1/2]

DLLEXPORT void QoreClass::addMethod ( const char *  n_name,
q_method_n_t  meth,
ClassAccess  access = Public,

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:

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().
