NodeIterator.filter
The NodeIterator.filter
read-only method returns a NodeFilter
object, that is an object implement an acceptNode(node)
method, used to screen nodes.
When creating the NodeIterator
, the filter object is passed in as the third parameter, and the object method acceptNode(node)
is called on every single node to determine whether or not to accept it. This function should return the constant NodeFilter.FILTER_ACCEPT
for cases when the node should be accepted and NodeFilter.FILTER_REJECT
for cases when the node should be rejected.
