Field Detail

emptyRange

public static final VersionRange emptyRange
An empty version range: "0.0.0". The empty version range includes all valid versions (any version greater than or equal to the version 0.0.0).

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. If null then Version.emptyVersion is used.
maxVersion - the maximum version of the range. If null then new Version(Integer.MAX_VALUE, Integer.MAX_VALUE, Integer.MAX_VALUE) is used.

VersionRange

public VersionRange(String versionRange)
Creates a version range from the specified string.

Here is the grammar for version range strings.

 version-range ::= interval | atleast
 interval ::= ( include-min | exclude-min ) min-version ',' max-version ( include-max | exclude-max )
 atleast ::= version
 floor ::= version
 ceiling ::= version
 include-min ::= '['
 exclude-min ::= '('
 include-max ::= ']'
 exclude-max ::= ')'
 

Parameters:
versionRange - string representation of the version range or null for the empty range "0.0.0"

Method Detail

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()
Deprecated. use VersionRange.getRight()

Returns the maximum Version of this VersionRange.

This method is deprecated. For ranges that have no maximum this method incorrectly returns a version equal to Version(Integer.MAX_VALUE, Integer.MAX_VALUE, Integer.MAX_VALUE). Use VersionRange.getRight() instead.

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

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.

Parameters:
version - a version to be tested for inclusion in this VersionRange. If null then Version.emptyVersion is used.
Returns:
true if the version is included, false otherwise
