    </dependency>
    ...

Gradle

Replace ${utility_version} with the current version.

dependencies {
    compile        "com.dua3.utility:utility:${utility_version}"
    compile        "com.dua3.utility:utility-db:${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 14, utility uses JSpecify annotations for all method parameters.

The resulting Jar files are instrumented using Cabe.

When you run your code with assertions disabled, virtually no overhead is introduced, as assertions are removed at 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 @NonNull annotated parameter. The assertion message contains the name of the parameter.

Logging

• all internal logging is done through log4j-api

Changes

15.0.2

• fix AwtFontUtil.deriveFont() always returning font instances with black text color

15.0.1

• added data.Converter interface
• added fx.PropertyConverter class to convert properties to properties of different types
• the Controls fluent builder interface supports bidirectional binding the selected state of ToggleButton and CheckBox instances to boolean properties

15.0.0

• BREAKING: font handling has been refactored for both AWT and JavaFX. Use FontUtil to get Font instances. To derive a font from a base font, use FontUtil as well.

  The Font class has been enhanced with methods to retrieve metric data like ascent, descent, and space width

  Memory footprint should be slightly reduced and performance increased for applications that dynamically allocate Font instances.

• small fixes and improvements

14.1.0

• BREAKING: when passing null as a non-nullable parameter, an IllegalArgumentException will be thrown (used to throw NullPointerException)
• Font.delta() now accepts null arguments
• IconView icon size and color properties are now bound bidirectional to the properties of the underlying ikonli icon

14.0.1

• add missing @Nullable in RichText.equalizer()
• update log4j to 2.24.2
• use log4j-bom
• improve logging in setTempFilePermissionsNonPosix();
• update cabe to final release

14

NOTE: starting with this release, for development builds of this library (i.e., builds that are neither release nor release candidate builds), return values of all methods returning a @NullMarked or @NonNull object (or derived) type are checked and will unconditionally throw an AssertionFailedError if the return value is found to be inconsistent.

Any AssertionError you encounter (with a message "invalid return value") means that you have found a bug in the library and are asked to open an issue against the library.

Release candidates and final releases will not contain any return value check.

Changes:

• org.jspecify annotations are used in the code base; all modules annotated with @NullMarked. That you may not pass null in any method or constructor parameter that is not explicitly annotated as @Nullable.
• module definitions have been reviewed.
• change type parameter for IoUtil.closeAll() to ? extends AutoCloseable
• complete Javadoc
• code cleanup and bug fixes
• XmlUtil.defaultInstance() and jaxpInstance() both return new instances for every invocation because the returned instances are not thread safe

• IoUtil.closeAll()
• code cleanup
• prevent serialization of logging related classes for security reasons
• javadoc

13.1.1

• FIX: do not throw an exception when temp directory permissions cannot be set, log a warning message instead. The reason is that especially the Files.setWriteable() does not seem to always return correct results, even when the
  directory does have the requested permissions.

13.1

• BREAKING: in the fx module, the methods Validator.matches() and Validator.notEmpty() have been renamed to setRegex() and disallowEmpty() to better express the fact that the content is not checked immediately but instead a rule is added that is validated at validation time
• IMPORTANT: resolved ambiguity of LangUtil.ConsumerThrows.andThen() overloads by renaming the version taking an argument of ConsumerThrows to andThenTry(); this might require a source change but code compiled using the previous version should still work in the same way
• IoUtil: added methods createSecureTempDirectory(), createSecureTempDirectoryAndDeleteOnExit(), deleteRecursiveOnExit()
• small improvements and code cleanup

13.0.2

• add overload of DataUtil.diff() that takes a map factory

13.0.1

• TextUtil.toString(Object obj, String valueIfNull)
• use HexFormat for converting Color instances to hex format

13

• new utility-fx modules with JavaFX related classes and components

• StreamUtil.concat() did not close streams
• SwingImageUtil, SwingFontUtil have been renamed to AwtImageUtil, AwtFontUtil as they are usable also in non-Swing applications
• Color methods have been renamed to reduce ambiguity
• SwingUtil.getDisplayScale() to retrieve the actual scaling factor for the display (taking into account UHD and retina displays)
• AffineTransformation2f.combine()
• return value of getTextDimension() changed to Rectangle2f (this gives access to the baseline value)
• Rectangle2f.getXCenter(), getYCenter(), min(), max(), center(), dimension(), withCenter()
• Dimension2f.scaled()
• Font.scaled()
• TextUtil.isBlank(CharSequence)
• toolkit agnostic Graphics interface and implementations for Swing and JavaFX
• code cleanups and reorganizations
• Javadoc additions
• many small fixes and improvements

• added documentation to the LogUtil classes about rerouting logging implementations
• code cleanup and minor fixes
• StopWatch.log...() returns an Object that does the formatting in the toString() method instead of a Supplier to integrate better with logging frameworks (this way, lambda support is not needed)
• TextUtil.nonEmptyOr()

12.2.1

• add LangUtil.require...() overloads for double and float arguments
• LangUtil.isBetween() will throw IllegalArgumentsException when an invalid intervall is specified instead of using an assertion

12.0.3

• fix record equals() not accepting null arguments
• make output of ArgumentsParser.help() more compact

12.0.2

• Use assertions to check parameters of internal methods, throw NPE for parameters to methods that are part of the public API. From now on, snapshots and beta versions will unconditionally throw AssertionErrors when null is passed to a parameter that isn't nullable. In release versions, standard assertions are used for internal methods while methods that are part of the public API will throw NullPointerExceptions.

• 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.
