Class JavaVersion

java.lang.Object
  com.mucommander.runtime.RuntimeProperty
      com.mucommander.runtime.ComparableRuntimeProperty
          com.mucommander.runtime.JavaVersion

All Implemented Interfaces:

JavaVersions, java.lang.Comparable

public class JavaVersion
extends ComparableRuntimeProperty
implements JavaVersions

This class represents a major version of Java, like Java 1.5 for instance. The current runtime instance is determined using the value of the java.version system property. Being a ComparableRuntimeProperty, versions of Java are ordered and can be compared against each other.

Method Detail

init

public static void init()

Determines the current value by parsing the corresponding system property. This method is called automatically by this class the first time the current value is accessed. However, this method has been made public to allow to force the initialization if it needs to happen at a predictable time.

getCurrent

public static JavaVersion getCurrent()

Returns the Java version of the current runtime environment.

Returns:

the Java version of the current runtime environment

getRawSystemProperty

public static java.lang.String getRawSystemProperty()

Returns the value of the system property which serves to detect the Java version at runtime.

Returns:

the value of the system property which serves to detect the Java version at runtime.

getCurrentValue

protected RuntimeProperty getCurrentValue()

Description copied from class: RuntimeProperty

Returns the current runtime environment's value of this runtime property.

Specified by:

getCurrentValue in class RuntimeProperty

Returns:

the current runtime environment's value of this runtime property
