Class DeltaCollector

Utility class to construct a sequence of attached operations from a matching.

Constructor

class DeltaCollector(matching, root_a, root_b)

Arguments:

• matching –
• root_a –
• root_b –

Methods

equals

DeltaCollector#equals(a, b)

Arguments:

• a –
• b –

Default equality test. Override this method if you need to test other node properties instead/beside node value.

forEachChange

DeltaCollector#forEachChange(callback, T, root_a, root_b, path)

Arguments:

• callback –

  A function(type, path, removes, inserts) called

  for each detected set of changes.

• T – Context object bound to “this” when the callback is
• root_a – (internal use) Root node in tree a
• root_b –

  (internal use) Root node in tree b

  invoked.

• path –

  (internal use) current path relative to base node. Used

  from recursive calls.

Invoke a callback for each changeset detected between tree a and tree b according to the given matching.
