Method Summary

Modifier and Type	Method	Description
static Version	defaultInitial(Scheme scheme)	Returns a Version instance representing the default initial value to use for the given scheme.
static boolean	isLegal(Scheme scheme, String s)	Returns true if the given string is a legal version which, for example, can be parsed using valueOf(Scheme, String) without exceptions using the implementation selected by the given scheme.
static boolean	isLegal(Scheme scheme, String s, boolean lenient)	Returns true if the given string is a legal version which, for example, can be parsed using valueOf(Scheme, String, boolean) without exceptions using the implementation selected by the given scheme.
static boolean	isLegal(Scheme scheme, String s, String prefix)	Returns true if the given string is a legal version which, for example, can be parsed using valueOf(Scheme, String, boolean) without exceptions using the implementation selected by the given scheme.
static Version	valueOf(Scheme scheme, String s)	Returns a Version instance representing the specified String value.
static Version	valueOf(Scheme scheme, String s, boolean sanitize)	Returns a Version instance representing the specified String value.
static Version	valueOf(Scheme scheme, String s, String prefix)	Returns a Version instance representing the specified String value.

Method Detail

defaultInitial

public static final Version defaultInitial(Scheme scheme)

Returns a Version instance representing the default initial value to use for the given scheme.

Parameters:

scheme - the scheme to get the initial version for

Returns:

the new Version instance representing the default initial value. The concrete class depends on the given scheme

Throws:

NullPointerException - if the given arguument is null

isLegal

public static boolean isLegal(Scheme scheme,
                              String s)

Returns true if the given string is a legal version which, for example, can be parsed using valueOf(Scheme, String) without exceptions using the implementation selected by the given scheme.
This method uses a strict criteria, without trying to sanitize the given string.

Parameters:

scheme - the scheme the check against.

s - the string version to check.

Returns:

true if the given string represents a legal version sing the implementation selected by the given scheme, false otherwise.

See Also:

valueOf(Scheme, String)

isLegal

public static boolean isLegal(Scheme scheme,
                              String s,
                              boolean lenient)

Returns true if the given string is a legal version which, for example, can be parsed using valueOf(Scheme, String, boolean) without exceptions using the implementation selected by the given scheme.
This method is different than isLegal(Scheme, String, String) as it also sanitizes extra characters in the body of the version identifier instead of just an optional prefix (when sanitize is true).

Parameters:

scheme - the scheme the check against.

s - the string version to check.

lenient - when true prefixes and non critical extra characters are tolerated even if they are not strictly legal from the version scheme specification perspective.

Returns:

true if the given string represents a legal version sing the implementation selected by the given scheme, false otherwise.

See Also:

valueOf(Scheme, String, boolean)

isLegal

public static boolean isLegal(Scheme scheme,
                              String s,
                              String prefix)

Returns true if the given string is a legal version which, for example, can be parsed using valueOf(Scheme, String, boolean) without exceptions using the implementation selected by the given scheme.
This method is different than isLegal(Scheme, String, boolean) as it only tolerates a prefix, while isLegal(Scheme, String, boolean) is more lenient as it also sanitizes extra characters in the body of the version identifier (when sanitize is true).

Parameters:

scheme - the scheme the check against.

s - the string version to check.

prefix - the initial string that is used for the version prefix. This will be stripped off from the given string representation of the version. It can be null or empty, in which case it's ignored. If not empty and the given version string doesn't start with this prefix, this prefix is ignored.

Returns:

true if the given string represents a legal version sing the implementation selected by the given scheme, false otherwise.

valueOf(Scheme, String, boolean)

valueOf

public static final Version valueOf(Scheme scheme,
                                    String s)

Returns a Version instance representing the specified String value. No sanitization attempt is done.

Parameters:

scheme - the scheme the version belongs to

s - the string to parse

Returns:

the new Version instance representing the given string. The concrete class depends on the given scheme

Throws:

NullPointerException - if a given arguument is null

IllegalArgumentException - if the given string doesn't represent a legal version, according to the selected scheme

valueOf

public static final Version valueOf(Scheme scheme,
                                    String s,
                                    boolean sanitize)

Returns a Version instance representing the specified String value. No sanitization attempt is done.
If sanitize is true this method will try to sanitize the given string before parsing so that if there are illegal characters like a prefix or leading zeroes in numeric identifiers they are removed.
When sanitization is enabled on a string that actually needs sanitization the string representation of the returned object will not exactly match the input value.
This method is different than valueOf(Scheme, String, String) as it also sanitizes extra characters in the body of the version identifier instead of just an optional prefix (when sanitize is true).

Parameters:

scheme - the scheme the version belongs to

s - the string to parse

sanitize - optionally enables sanitization before parsing

Returns:

the new Version instance representing the given string. The concrete class depends on the given scheme

Throws:

NullPointerException - if a given arguument is null

IllegalArgumentException - if the given string doesn't represent a legal version, according to the selected scheme

valueOf

public static final Version valueOf(Scheme scheme,
                                    String s,
                                    String prefix)

Returns a Version instance representing the specified String value.
This method is different than valueOf(Scheme, String, boolean) as it only tolerates a prefix, while valueOf(Scheme, String, boolean) is more lenient as it also sanitizes extra characters in the body of the version identifier (when sanitize is true).

Parameters:

scheme - the scheme the version belongs to

s - the string to parse

prefix - the initial string that is used for the version prefix. This will be stripped off from the given string representation of the version. It can be null or empty, in which case it's ignored. If not empty and the given version string doesn't start with this prefix, this prefix is ignored.

Returns:

the new Version instance representing the given string. The concrete class depends on the given scheme

Throws:

NullPointerException - if a given arguument is null

IllegalArgumentException - if the given string doesn't represent a legal version, according to the selected scheme
