Function Documentation

◆ get_param_value()

static QoreValue get_param_value ( const QoreListNode n,
qore_size_t  i 
)
inlinestatic

returns the argument in the position given or 0 if there is none

Parameters
na pointer to the argument list
ithe offset in the list to test (first element is offset 0)
Returns
the argument in the position given or 0 if there is none

References QoreListNode::retrieveEntry().

◆ num_args()

static unsigned num_args ( const QoreListNode n)
inlinestatic

returns the number of arguments passed to the function

Parameters
na pointer to the argument list
Returns
the number of arguments passed to the function

References QoreListNode::size().

◆ num_params()

static unsigned num_params ( const QoreListNode n)
inlinestatic

returns the number of arguments passed to the function

Parameters
na pointer to the argument list
Returns
the number of arguments passed to the function

References QoreListNode::size().

◆ test_reference_param()

static const ReferenceNode* test_reference_param ( const QoreListNode n,
qore_size_t  i 
)
inlinestatic

returns a ReferenceNode pointer for the argument position given or 0 if there is no argument there or if the argument is not a ReferenceNode

Note that this will also return a value for a closure; this is a synonym for test_funcref_param

Parameters
na pointer to the argument list
ithe offset in the list to test (first element is offset 0)
Returns
a ReferenceNode pointer for the argument position given or 0 if there is no argument there or if the argument is not a ReferenceNode
