Obsolete Pointer Functions

this_node()

Syntax:

n.this_node(x)
n.this_node(x, sec=section)
Description:

Return a pointer (coded as a double) to the segment of section that contains location x. If no section is specified, it uses the currently accessed section; see cas(). If you wish to compute a segment number index where 1 is the first nonzero area segment and nseg is the last nonzero area segment of the currently accessed section corresponding to position x use the hoc function

Warning

This function is useless and should be removed.

Syntax:

this_node(x)

Description:

Return a pointer (coded as a double) to the segment of the currently accessed section that contains location x. If you wish to compute a segment number index where 1 is the first nonzero area segment and nseg is the last nonzero area segment of the currently accessed section corresponding to position x use the hoc function

func segnum() {
        if ($1 <= 0) {
                return 0
        }else if ($1 >= 1) {
                return nseg+1
        }else {
                return int($1*nseg + .5)
        }
}

Warning

This function is useless and should be removed.

this_section()

Syntax:

n.this_section(x)
Description:

Return a pointer (coded as a double) to the section which contains location 0 of the currently accessed section. This pointer can be used as the argument to push_section(). Functions that return pointers coded as doubles are unsafe with 64 bit pointers. This function has been superseded by SectionRef and in Python the use of Section objects.
