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.

n_name	the name of the class
n_domain	the functional domain of the class to be used to enforce functional restrictions within a Program object

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

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`,
