Detailed Description

contains constants, classes, and subnamespaces in QoreProgram objects

Constructor & Destructor Documentation

◆ QoreNamespace()

DLLEXPORT QoreNamespace::QoreNamespace ( const char *  n)

creates a namespace with the given name

the name of a subnamespace must be unique in the parent namespace and must not have the same name as a class in the parent namespace either

Parameters
nthe name of the namespace

Member Function Documentation

◆ addConstant() [1/2]

DLLEXPORT void QoreNamespace::addConstant ( const char *  name,
QoreValue  value 
)

adds a constant definition to the namespace

use addConstant(const char* name, QoreValue value, const QoreTypeInfo* typeInfo) when adding constants of externally-defined base (non-class) types; all other types (and all objects) can have their type information automatically added

Parameters
namethe name of the constant to add
valuethe value of the constant

◆ addConstant() [2/2]

DLLEXPORT void QoreNamespace::addConstant ( const char *  name,
QoreValue  value,
const QoreTypeInfo *  typeInfo 
)

adds a constant definition to the namespace with type information

Parameters
namethe name of the constant to add
valuethe value of the constant
typeInfothe type of the constant

QoreTypeInfoHelper

◆ addInitialNamespace()

DLLEXPORT void QoreNamespace::addInitialNamespace ( QoreNamespace ns)

adds a subnamespace to the namespace

use this function when the QoreNamespace can be added directly to the tree (does not need to be merged with another namespace of the same name and does not contain user code)

Parameters
nsthe subnamespace to add to the namespace

◆ addNamespace()

DLLEXPORT void QoreNamespace::addNamespace ( QoreNamespace ns)

adds a namespace to the namespace tree

the namespace must be unique, must also not clash with a class name in the same parent namespace

Parameters
nsthe namespace to add, memory is now owned by parent namespace

◆ addSystemClass()

DLLEXPORT void QoreNamespace::addSystemClass ( QoreClass oc)

adds a class to a namespace

Parameters
octhe class to add to the namespace

◆ addSystemHashDecl()

DLLEXPORT void QoreNamespace::addSystemHashDecl ( TypedHashDecl hashdecl)

adds a hashdecl to a namespace

Parameters
hashdeclthe hashdecl to add to the namespace
Since
Qore 0.8.13

◆ clear()

DLLEXPORT void QoreNamespace::clear ( ExceptionSink xsink)

clears the contents of the namespace before deleting

use if the namespace could contain objects

Since
Qore 0.8.13

◆ copy() [1/2]

DLLEXPORT QoreNamespace* QoreNamespace::copy ( int  po) const

returns a deep copy of the namespace; DEPRECATED: use copy(int64) instead

Parameters
poparse options to use when copying the namespace
Returns
a deep copy of the namespace

◆ copy() [2/2]

DLLEXPORT QoreNamespace* QoreNamespace::copy ( int64  po = PO_DEFAULT) const

returns a deep copy of the namespace

Parameters
poparse options to use when copying the namespace
Returns
a deep copy of the namespace

◆ findCreateNamespacePath()

DLLEXPORT QoreNamespace* QoreNamespace::findCreateNamespacePath ( const char *  nspath)

finds a Namespace based on the argument; creates it (or the whole path) if necessary

can only be called in the parse lock

Parameters
nspathmust be a complete path ("ns1::ns2[::ns3...]" to a namespace, which will be found or created in this namespace
Returns
the namespace found or created according to the path
Note
namespaces are created private by default

◆ findLocalClass()

DLLEXPORT QoreClass* QoreNamespace::findLocalClass ( const char *  cname) const

finds a class in this namespace, does not search child namespaces

can only be called in the parse lock does not call the class handler

Parameters
cnamethe class name to find in this namespace, must be unqualified (without a namespace path)
Returns
the class found or 0 if not present

◆ findLocalConstant()
