Function Documentation

get_param_value()

static QoreValue get_param_value ( const QoreListNode *  n, size_t  i  )

inlinestatic

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

Parameters

n	a pointer to the argument list
i	the 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

n	a 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

n	a 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, 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

n	a pointer to the argument list
i	the 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
