:relfileprefix: ../../
:mrdocs:

Remove the specified positions from this DepGraph.

== Synopsis

Declared in `<cluster_linearize.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
void
RemoveTransactions(SetType const& del) noexcept;
----

== Description

The specified positions will no longer be part of Positions(), and dependencies with them are removed. Note that due to DepGraph only tracking ancestors/descendants (and not direct dependencies), if a parent is removed while a grandparent remains, the grandparent will remain an ancestor.

Complexity: O(N) where N=TxCount().

== Parameters

[cols="1,4"]
