From e684262ca6c2aba6ca58283e81376de7f98debc1 Mon Sep 17 00:00:00 2001 From: Cédric Walter Date: Mon, 31 Mar 2014 15:54:52 +0000 Subject: performance issue logging calls are expensive because of the objects created when assembling the log messages. Using the check() method of the logging sub-system can prevent object creation git-svn-id: https://svn.apache.org/repos/asf/poi/trunk@1583357 13f79535-47bb-0310-9956-ffa450edef68 --- .../org/apache/poi/ddf/EscherContainerRecord.java | 4 +- .../org/apache/poi/ddf/EscherMetafileBlip.java | 54 ++++++++--------- .../org/apache/poi/hssf/model/InternalSheet.java | 4 +- .../org/apache/poi/hslf/model/PPGraphics2D.java | 68 ++++++++++++++++------ .../org/apache/poi/hwpf/model/FIBFieldHandler.java | 8 ++- .../src/org/apache/poi/hwpf/model/ListTables.java | 4 +- .../apache/poi/hwpf/model/NilPICFAndBinData.java | 9 ++- .../src/org/apache/poi/hwpf/model/PlfLfo.java | 8 ++- .../src/org/apache/poi/hwpf/model/Xstz.java | 6 +- 9 files changed, 108 insertions(+), 57 deletions(-) diff --git a/src/java/org/apache/poi/ddf/EscherContainerRecord.java b/src/java/org/apache/poi/ddf/EscherContainerRecord.java index 860edd8071..8454231cf1 100644 --- a/src/java/org/apache/poi/ddf/EscherContainerRecord.java +++ b/src/java/org/apache/poi/ddf/EscherContainerRecord.java @@ -85,7 +85,9 @@ public final class EscherContainerRecord extends EscherRecord { addChildRecord(child); if (offset >= data.length && bytesRemaining > 0) { _remainingLength = bytesRemaining; - log.log(POILogger.WARN, "Not enough Escher data: " + bytesRemaining + " bytes remaining but no space left"); + if (log.check(POILogger.WARN)) { + log.log(POILogger.WARN, "Not enough Escher data: " + bytesRemaining + " bytes remaining but no space left"); + } } } return bytesWritten; diff --git a/src/java/org/apache/poi/ddf/EscherMetafileBlip.java b/src/java/org/apache/poi/ddf/EscherMetafileBlip.java index 428d11e4e9..f1444b9843 100644 --- a/src/java/org/apache/poi/ddf/EscherMetafileBlip.java +++ b/src/java/org/apache/poi/ddf/EscherMetafileBlip.java @@ -254,31 +254,31 @@ public final class EscherMetafileBlip extends EscherBlipRecord { " Filter: " + HexDump.toHex( field_7_fFilter ) + '\n' + " Extra Data:" + '\n' + extraData + (remainingData == null ? null : ("\n" + - " Remaining Data: " + HexDump.toHex(remainingData, 32))); - } - - @Override - public String toXml(String tab) { - String extraData = ""; - StringBuilder builder = new StringBuilder(); - builder.append(tab).append(formatXmlRecordHeader(getClass().getSimpleName(), HexDump.toHex(getRecordId()), HexDump.toHex(getVersion()), HexDump.toHex(getInstance()))) - .append(tab).append("\t").append("0x").append(HexDump.toHex( field_1_UID ) + '\n' + - (field_2_UID == null ?
