From 010a8c96c15d8f4b96bb3057988a03a42a1098f1 Mon Sep 17 00:00:00 2001 From: maximthomas Date: Sun, 11 Oct 2026 21:12:06 +0300 Subject: [PATCH 01/16] [#157] Add an index of XML entries by __UID__ and __NAME__ Identifier lookups in the XML connector walk the whole DOM today, which is quadratic on Xerces. EntryIndex keeps entries by class and by __UID__ and __NAME__ so these lookups no longer walk the document. It mirrors the XQuery /icf:OpenICFContainer//ri:CLASS[$x/icf:FIELD = 'VALUE'] in result and order. --- .../openicf/connectors/xml/EntryIndex.java | 237 ++++++++++++++++++ .../connectors/xml/EntryIndexTests.java | 192 ++++++++++++++ 2 files changed, 429 insertions(+) create mode 100644 OpenICF-xml-connector/src/main/java/org/forgerock/openicf/connectors/xml/EntryIndex.java create mode 100644 OpenICF-xml-connector/src/test/java/org/forgerock/openicf/connectors/xml/EntryIndexTests.java diff --git a/OpenICF-xml-connector/src/main/java/org/forgerock/openicf/connectors/xml/EntryIndex.java b/OpenICF-xml-connector/src/main/java/org/forgerock/openicf/connectors/xml/EntryIndex.java new file mode 100644 index 00000000..ab7cc055 --- /dev/null +++ b/OpenICF-xml-connector/src/main/java/org/forgerock/openicf/connectors/xml/EntryIndex.java @@ -0,0 +1,237 @@ +/* + * The contents of this file are subject to the terms of the Common Development and + * Distribution License (the License).
