Method Detail

fromPath

public void fromPath(String path)

Sets the stem from a path like a.b.c.d, resulting in a value of

['a','b','c','d']

N.B. that the first element is not the stem. The result is a simple path that can be used to access the element. This crops up a fair bit in system programming.

Parameters:

path -
