    ...

Gradle

Replace ${utility_version} with the current version.

dependencies {
    compile        "com.dua3.utility:utility:${utility_version}"

    ...        
}

Logging

As of version 12.0.0, logging changed from SLF4J to Log4J-API!

You can use whatever logging implementation you want, for configuration refer to the Log4J documentation. You can also look at the swing samples that use a SwingLogPane and route all logging output regardless of source (Log4J, SLF4J, JUL) to the logging implementation.

utility-logging

This project adds a small lightweight implementation that can be used instead of SLF4J SimpleLogger. It is intended as a lightweight logging implementation in desktop applications or during development and does not support advanced features such as log rotation or writing to a database.

Configuration is done by providing a file called logging.properties on the classpath.

• configure log level:

   logger.level = (ERROR|WARN|INFO|DEBUG|TRACE)(, <prefix>:(ERROR|WARN|INFO|DEBUG|TRACE))*
  

  setting ony the global level:

   logger.level = INFO
  

  setting global level and different levels for packages:

   logger.level = WARN, com.dua3.:DEBUG, my.current.project.:TRACE
  

• configure logging to console

   logger.console.stream = system.out|system.err
   logger.console.colored = true|false
  

• configure a log buffer (see below):

  logger.buffer = #entries
  

Using SLF4J with different logging frameworks

Just to save time searching the internet for this:

• JUL (java.util.logging)

  • add "org.slf4j:jul-to-slf4j:" to your dependencies

  • when using JPMS modules, add requires jul.to.slf4j; to your module-info.java

  • initialize the bridge handler:

    static {
        java.util.logging.LogManager.getLogManager().reset();
        SLF4JBridgeHandler.install();
    }
    

• Log4J2

  • add "org.apache.logging.log4j:log4j-to-slf4j:2.18.0" to your dependencies

SwingLogPane (Swing-widget for log viewing)

If you want to show logs in a swing application, configure a log buffer and add a SwingLogPane to your UI. Have a look at the code of SwingComponentsSample for details.

Using the BuildInfo class in Gradle builds

Add this to your build.gradle to include a build.properties file in your JAR:

// === generate BuildInfo ===
def generateBuildInfo = tasks.register('generateBuildInfo') {
    // do not cache the buildinfo
    outputs.upToDateWhen { false }

    // create build.properties
    doLast {
        def resourcesDir = sourceSets.main.output.resourcesDir
        resourcesDir.mkdirs()

        def buildTime = OffsetDateTime.now().atZoneSameInstant(ZoneId.of("UTC"))
        def contents = "build.time=${buildTime}\nbuild.version=${version}\n"

        def file = new File(resourcesDir, "build.properties")
        file.text = contents
    }
}

Add this in your code to read the build.properties file and create a BuildInfo instance containing version and build time information:

public static final BuildInfo BUILD_INFO = BuildInfo.create(Main.class, "/build.properties");

Cabe

Starting with version 10, utility uses cabe. Cabe is a library that is used only at compile time and does not introduce any dependencies for downstream projects. It contains source-only annotations that are not present in the compiled class files of the processed sources.

When you run your code with assertions disabled, virtually no overhead is introduced, as assertions are removed on the JVM level.

When running your code with exceptions enabled, parameters are checked for invalid null values and an AssertionError will be generated when null is passed for a @NotNull annotated parameter. The assertion message contains the name of the parameter.

Logging

• all internal logging is done through log4j-api instead of slf4j
• introduced util-logging-slf4j as sub project of util-logging. Note that util-logging is not intended as a production logging replacement. It is intended to provide utilites to capture and display log data in an application window.

• Better documentation for MathUtil.round() and MathUtil.roundToPrecision()
• fixed some compilation warnings

Version 4.1.0-BETA8

• DataUtil.collect() and DataUtil.collectArray()

Version 4.1.0-BETA7

Version 4.1.0-BETA4

• Support converting Long, Integer to Double, Float in DataUtil.convert...()-methods

Version 4.1.0-BETA3

• Support converting String to LocalDate in the DataUtil.convert...()-methods

Version 4.1.0-BETA2

• DataUtil.convert() and DataUtil.convertToArray() for converting objects to other types. Conversion is done as follows:
  • if value is {@code null}, {@code null} is returned;
  • if the target class is assignment compatible, a simple cast is performed;
  • if the target class is String, Object.toString() is used;
  • if the target class is an integer type and the value is of type double, a conversion without loss of precision is tried;
  • if the target class provides a method public static T valueOf(T) and value instanceof U, that method is invoked;
  • if useConstructor is true and the target class provides a constructor taking a single argument of value's type, that constructor is used;
  • otherwise an exception is thrown.

Version 4.0.8

• new class DataUtil, methods for data conversion

Version 4.0.7

• new helper method TextUtil.align()

Version 4.0.6

BETA 4

• changed the build system to make life easier for me as developer :) - version information is stored in a file named version in the project root. This makes it possible to consistently update dependencies information automatically using a script.

BETA 3

• set dependency version information in gradle.properties file
• JdbcDriverInfo: create connection URL from option values

BETA 2

• don't use decimal grouping in CSV output
• ValueChangeListener support in OptionValues
• classes FileType and OpenMode
• fix CSV date formatting issues

BETA 1

• update gradle wrapper
• CsvReader and CsvWriter classes
• new classes Option (an option to control object behavior), OptionSet (a set of options to control object behavior), and Options (a set of options and corresponding values)
• new package com.dua3.utility.data with classes TreeNode (to build tree data structures) and FileTreeNode to create a tree of files and subdirectories of a directory
• moved the Pair and Color classes to the com.dua3.utility.data package
• renamed Options to OptionValues

Version 3.1.4

• add uses declarations in module-info.java files (fix ServiceLoader issues when run from eclipse)
• spotbugs: use exclude filter for false positives; don't ignore failures

Version 3.1.3

• Added methods to measure text in TextUtil. The concrete implementation is using either AWT or JavaFX and is loaded via a ServiceLoader. The AWT implementation is included in utility.swing whereas a JavaFX implementation is included in the fx.util subproject of the fx project.

Version 3.1.2

• skipped

Version 3.1.1

• Fix NamedParameterStatement throwing exception when using ojdbc8.jar with certain statements.

Version 3.1.0

• The git repository moved to https://gitlab.com/com.dua3/lib/utility.git
• Added NamedParameterStatement.getParameterInfo() and NamedParameterStatement.getParameterInfo(String) to query parameter meta data (i.e. the corresponding SQL type)
• Added NamedParameterStatement.getResultSet()
• Added NamedParameterStatement.getUpdateCount()
• Added DbUtil.toLocalTime()

VERSION 3.0.1

• changed license to MIT to make it possible to use in pre-V3 GPL projects

VERSION 3.0

• BREAKING: package com.dua3.utility.db was moved to a separate library utility.db. You have to update dependencies and module-info.
• REMOVED: Font.getAwtFont() and Font.getTextWidth(); these introduced a dependency on java.desktop and can be easily replaced where needed.
• The utility.db library now include methods to dynamically load JDBC drivers. This allows to use jlink on applications that use non-modular JDBC-drivers.
• dependencies on these modules were removed from the main library, allowing for smaller jlink images:
  • java.xml
  • java.desktop
  • java.sql

version 2.2

• New class CryptUtil: encryption and decryption utility.
• TextUtil.base64Encode()
• TextUtil.base64Decode()
