JdkVersion
abstract public class JdkVersion (Code)
	Internal helper class used to find the Java/JDK version that Spring is operating on, to allow for automatically adapting to the present platform's capabilities. Note that Spring does not support 1.2 or earlier JVMs. author: Rod Johnson author: Juergen Hoeller author: Rick Evans

Field Summary
final public static int	JAVA_13 Constant identifying the 1.3.x JVM (JDK 1.3).
final public static int	JAVA_14 Constant identifying the 1.4.x JVM (J2SE 1.4).
final public static int	JAVA_15 Constant identifying the 1.5 JVM (Java 5).
final public static int	JAVA_16 Constant identifying the 1.6 JVM (Java 6).
final public static int	JAVA_17 Constant identifying the 1.7 JVM.

Method Summary
public static String	getJavaVersion() Return the full Java version string, as returned by `System.getProperty("java.version")`.
public static int	getMajorJavaVersion() Get the major version code.
public static boolean	isAtLeastJava14() Convenience method to determine if the current JVM is at least Java 1.4.
public static boolean	isAtLeastJava15() Convenience method to determine if the current JVM is at least Java 1.5 (Java 5).

Field Detail

JAVA_13
final public static int JAVA_13(Code)
	Constant identifying the 1.3.x JVM (JDK 1.3).

JAVA_14
final public static int JAVA_14(Code)
	Constant identifying the 1.4.x JVM (J2SE 1.4).

JAVA_15
final public static int JAVA_15(Code)
	Constant identifying the 1.5 JVM (Java 5).

JAVA_16
final public static int JAVA_16(Code)
	Constant identifying the 1.6 JVM (Java 6).

JAVA_17
final public static int JAVA_17(Code)
	Constant identifying the 1.7 JVM.

Method Detail

getJavaVersion
public static String getJavaVersion()(Code)
	Return the full Java version string, as returned by `System.getProperty("java.version")`. the full Java version string See Also: System.getProperty(String)

getMajorJavaVersion
public static int getMajorJavaVersion()(Code)
	Get the major version code. This means we can do things like `if (getMajorJavaVersion() < JAVA_14)`. a code comparable to the JAVA_XX codes in this class See Also: JdkVersion.JAVA_13 See Also: JdkVersion.JAVA_14 See Also: JdkVersion.JAVA_15 See Also: JdkVersion.JAVA_16 See Also: JdkVersion.JAVA_17

isAtLeastJava14
public static boolean isAtLeastJava14()(Code)
	Convenience method to determine if the current JVM is at least Java 1.4. `true` if the current JVM is at least Java 1.4 See Also: JdkVersion.getMajorJavaVersion() See Also: JdkVersion.JAVA_14 See Also: JdkVersion.JAVA_15 See Also: JdkVersion.JAVA_16 See Also: JdkVersion.JAVA_17

isAtLeastJava15
public static boolean isAtLeastJava15()(Code)
	Convenience method to determine if the current JVM is at least Java 1.5 (Java 5). `true` if the current JVM is at least Java 1.5 See Also: JdkVersion.getMajorJavaVersion() See Also: JdkVersion.JAVA_15 See Also: JdkVersion.JAVA_16 See Also: JdkVersion.JAVA_17
