Field Detail

emptyRange

public static final VersionRange emptyRange

TODO: This should not be OSGi but it has to be that for now since the resolver creates a filter where the min and max are converted into strings. When the filter is evaluated an attempt is made to recreate them as OSGi versions. An empty OSGi Version range.

Constructor Detail

VersionRange

public VersionRange(Version minVersion,
                    boolean includeMin,
                    Version maxVersion,
                    boolean includeMax)

Constructs a VersionRange with the specified minVersion and maxVersion.

Parameters:

minVersion - the minimum version of the range

maxVersion - the maximum version of the range

VersionRange

public VersionRange(String versionRange)

Constructs a VersionRange from the given versionRange String.

Parameters:

versionRange - a version range String that specifies a range of versions.

Method Detail

create

public static VersionRange create(String versionRange)

Parses a version range from the specified string.

Note that this method performs a non thread-safe object pooling. Instances are stored in a weak cache, i.e. for multiple calls with the same input it is likely but not guaranteed that the same instance is retrieved. Same holds for concurrent access on this method. Clients must not assume to get the same instance for subsequent calls.

Parameters:

versionRange - String representation of the version range. Leading and trailing whitespace will be ignored.

Returns:

A VersionRange object representing the version range or null if versionRange is null or an empty string.

Throws:

IllegalArgumentException - If versionRange is improperly formatted.

Since:

2.4

getFormat

public IVersionFormat getFormat()

Returns the version format.

getMinimum

public Version getMinimum()

Returns the minimum Version of this VersionRange

Returns:

the minimum Version of this VersionRange

getIncludeMinimum

public boolean getIncludeMinimum()

Indicates if the minimum version is included in the version range.

Returns:

true if the minimum version is included in the version range; otherwise false is returned

getMaximum

public Version getMaximum()

Returns the maximum Version of this VersionRange

Returns:

the maximum Version of this VersionRange

getIncludeMaximum

public boolean getIncludeMaximum()

Indicates if the maximum version is included in the version range.

Returns:

true if the maximum version is included in the version range; otherwise false is returned

intersect

public VersionRange intersect(VersionRange r2)

isIncluded

public boolean isIncluded(Version version)

Returns whether the given version is included in this VersionRange. This will depend on the minimum and maximum versions of this VersionRange and the given version.
