Parameters

major:int: the major class file version as an integer

Returns:ClassFileFormatVersion

the latest class file format version whose major class file version matches the argument

Exceptions

IllegalArgumentException:: if the argument is outside of the range of major class file versions

runtimeVersion back to summary

runtimeVersion	back to summary
public Runtime.Version runtimeVersion() Returns the least runtime version that supports this class file format version; otherwise `null`. The returned runtime version has a feature large enough to support this class file format version and has no other elements set. Class file format versions greater than or equal to `RELEASE_6` have non-`null` results. Returns:Runtime.Version the least runtime version that supports this class file format version; otherwise `null`

public Runtime.Version runtimeVersion()

Returns the least runtime version that supports this class file format version; otherwise null. The returned runtime version has a feature large enough to support this class file format version and has no other elements set. Class file format versions greater than or equal to RELEASE_6 have non-null results.

Returns:Runtime.Version: the least runtime version that supports this class file format version; otherwise null

valueOf back to summary

valueOf	back to summary
public static ClassFileFormatVersion valueOf(Runtime.Version rv) Returns the latest class file format version that is usable under the runtime version argument. If the runtime version's feature is greater than the feature of the runtime version of the latest class file format version, an `IllegalArgumentException` is thrown. Because the class file format versions of the Java platform have so far followed a linear progression, only the feature component of a runtime version is queried to determine the mapping to a class file format version. If that linearity changes in the future, other components of the runtime version may influence the result. API Note An expression to convert from a string value, for example `"17"`, to the corresponding class file format version, `RELEASE_17`, is: `ClassFileFormatVersion.valueOf(Runtime.Version.parse("17"))` ClassFileFormatVersion.valueOf(Runtime.Version.parse("17")) Parameters rv:Runtime.Version runtime version to map to a class file format version Returns:ClassFileFormatVersion the latest class file format version that is usable under the runtime version argument Exceptions NullPointerException: if `rv` is `null` IllegalArgumentException: if the feature of version argument is greater than the feature of the platform version.

public static ClassFileFormatVersion valueOf(Runtime.Version rv)

Returns the latest class file format version that is usable under the runtime version argument. If the runtime version's feature is greater than the feature of the runtime version of the latest class file format version, an IllegalArgumentException is thrown.

Because the class file format versions of the Java platform have so far followed a linear progression, only the feature component of a runtime version is queried to determine the mapping to a class file format version. If that linearity changes in the future, other components of the runtime version may influence the result.

API Note

An expression to convert from a string value, for example "17", to the corresponding class file format version, RELEASE_17, is:

ClassFileFormatVersion.valueOf(Runtime.Version.parse("17"))

Parameters

rv:Runtime.Version: runtime version to map to a class file format version

Returns:ClassFileFormatVersion

the latest class file format version that is usable under the runtime version argument

Exceptions

NullPointerException:: if rv is null
IllegalArgumentException:: if the feature of version argument is greater than the feature of the platform version.
