Introduction

The purpose of this Terracotta integration module (TIM) is to enable cluster autolocking on certain Java synchronized collections. This TIM is actually a set of several individual TIMs aimed at integrating synchronized collections. It includes Hashtable , Vector , and synchronized wrapper collections returned by the Collections.synchronized*() methods.

Dependencies

None.

Usage

After you download and unpack the synchronized Java collection TIMs into the Terracotta modules directory, add the following to your tc-config.xml:

<clients>
   <modules>
      <module name="tim-hashtable" version="2.2.0" group-id="org.terracotta.modules"/>
      <module name="tim-synchronizedcollection" version="2.2.0" group-id="org.terracotta.modules"/>
      <module name="tim-synchronizedmap" version="2.2.0" group-id="org.terracotta.modules"/>
      <module name="tim-synchronizedset" version="2.2.0" group-id="org.terracotta.modules"/>
      <module name="tim-synchronizedsortedmap" version="2.2.0" group-id="org.terracotta.modules"/>
      <module name="tim-synchronizedsortedset" version="2.2.0" group-id="org.terracotta.modules"/>
      <module name="tim-vector" version="2.2.0" group-id="org.terracotta.modules"/>
   </modules>
</clients>

The <module> elements shown are configured for TIMs installed in the <TC_HOME>/modules/org/terracotta/modules directory. For information on installing TIMs in other directories, see the Configuration Guide and Reference.

To avoid using a synchronized Java collection TIM, do not enter a <module> element for it in tc-config.xml.

Known Issues

None.
