Welcome to the Berkeley DB (DB) Collections API. This document provides a tutorial that introduces the collections API. The goal of this document is to provide you with an efficient mechanism with which you can quickly become efficient with this API. As such, this document is intended for Java developers and senior software architects who are looking for transactionally-protected backing of their Java collections. No prior experience with DB technologies is expected or required.
This document reflects Berkeley DB 11g Release 2, which provides DB library version 11.2.5.2.
The following typographical conventions are used within in this manual:
Class names are represented in monospaced font, as are method
names. For example: "The Environment.openDatabase() method
returns a Database class object."
Variable or non-literal text is presented in italics. For example: "Go to your DB_INSTALLATION_HOME directory."
Program examples are displayed in a monospaced font on a shaded background. For example:
import com.sleepycat.db.Environment; import com.sleepycat.db.EnvironmentConfig; import java.io.File; ... // Open the environment. Allow it to be created if it does not already // exist. Environment myDbEnvironment;
In situations in this book, programming examples are updated from one chapter to the next in this book. When
this occurs, the new code is presented in monospaced bold font. For example:
import com.sleepycat.db.Environment;
import com.sleepycat.db.EnvironmentConfig;
import java.io.File;
...
// Open the environment. Allow it to be created if it does not already
// exist.
Environment myDbEnv;
EnvironmentConfig envConfig = new EnvironmentConfig();
envConfig.setAllowCreate(true);
myDbEnv = new Environment(new File("/export/dbEnv"), envConfig);
