Constructor Detail

ClickHouseVersion

protected ClickHouseVersion(boolean latest,
                            int year,
                            int feature,
                            int maintenance,
                            int build)

Method Detail

check

public static boolean check(String version,
                            String range)

Checks if the version is valid according to the given maven-like version range. For examples:

• 21.3 21.3.x.x, short version of [21.3,21.4)
• [21.3,21.4) 21.3.x.x (included) to 21.4.x.x (not included)
• [21.3,21.4] 21.3.x.x to 21.4.x.x (both included)
• [21.3,) 21.3.x.x or higher
• (,21.3],[21.8,) to 21.3.x.x (included) and 21.8.x.x or higher

Parameters:

version - version, null is treated as 0.0.0.0

range - maven-like version range, null or empty means always invalid

Returns:

true if the version is valid; false otherwise

compare

public static int compare(String fromVersion,
                          String toVersion)

Compares two versions part by part, which is not semantical. For example: compare("21.3.1", "21.3") > 0, because "21.3.1.0" is greater than "21.3.0.0". However, check("21.3.1", "(,21.3]") == true, since "21.3.1" is considered as part of "21.3" series.

Parameters:

fromVersion - version

toVersion - version to compare with

Returns:

positive integer if fromVersion is newer than toVersion; zero if they're equal; or negative integer if fromVersion is older

of

public static ClickHouseVersion of(String version)

Parses the given string to extract version. Behind the scene, cache is used to avoid unnecessary overhead.

Parameters:

version - version, null or empty string is treated as 0.0.0.0

Returns:

parsed version

parseVersion

protected static ClickHouseVersion parseVersion(String version)

Parses given version without caching.

Parameters:

version - version, null or empty string is treated as 0.0.0.0

Returns:

parsed version

compareTo

protected int compareTo(ClickHouseVersion o,
                        boolean sameSeriesComparison)

Compares current version and the given one. When includeEmptyParts is true, this method returns 0(instead of 1) when comparing '21.3.1.2' with '21.3', because they're in the same series of '21.3'.

Parameters:

o - the object to be compared

sameSeriesComparison - whether compare if two version are in same series

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object

belongsTo

public boolean belongsTo(ClickHouseVersion version)

Checks if the version belongs to the given series. For example: 21.3.1.1 belongs to 21.3 series but not 21.4 or 21.3.2.

Parameters:

version - version series, null will be treated as 0.0.0.0

Returns:

true if the version belongs to the given series; false otherwise

belongsTo

public boolean belongsTo(String version)

Checks if the version belongs to the given series. For example: 21.3.1.1 belongs to 21.3 series but not 21.4 or 21.3.2.

Parameters:

version - version series

Returns:

true if the version belongs to the given series; false otherwise

isLatest

public boolean isLatest()

Checks if the version is latest or not.

Returns:

true if it's latest; false otherwise

getYear

public int getYear()

Gets year number.

Returns:

year number

getFeatureRelease

public int getFeatureRelease()

Gets feature release.

Returns:

feature release

getMaintenanceRelease

public int getMaintenanceRelease()

Gets maintenance release.

Returns:

maintenance release

getBuilderNumber

public int getBuilderNumber()

Gets build number.

Returns:

build number

getMajorVersion

public int getMajorVersion()

Gets major version in semantic versioning. Same as getYear().

Returns:

major version

getMinorVersion

public int getMinorVersion()

Gets minor version in semantic versioning. Same as getFeatureRelease().

Returns:

minor version

getPatch

public int getPatch()

Gets patch in semantic versioning. Same a getMaintenanceRelease().

Returns:

patch

isNewerOrEqualTo

public boolean isNewerOrEqualTo(ClickHouseVersion version)

Checks if the version is newer or equal to the given one. Pay attention that when comparing "21.3.1.1" to "21.3", compareTo(ClickHouseVersion) says the former is greater, but this method will return false(because 21.3.x.x still belongs to 21.3 series).

Parameters:

version - version to compare

Returns:

true if the version is newer or equal to the given one; false otherwise

isNewerOrEqualTo

public boolean isNewerOrEqualTo(String version)

Checks if the version is newer or equal to the given one. Pay attention that when comparing "21.3.1.1" to "21.3", compareTo(ClickHouseVersion) says the former is greater, but this method will return false(because 21.3.x.x still belongs to 21.3 series).

Parameters:

version - version to compare

Returns:

true if the version is newer or equal to the given one; false otherwise

isNewerThan

public boolean isNewerThan(ClickHouseVersion version)

Checks if the version is newer than the given one. Same as compareTo(version) > 0.

Parameters:

version - version to compare

Returns:

true if the version is newer than the given one; false otherwise

isNewerThan

public boolean isNewerThan(String version)

Checks if the version is newer than the given one. Same as compareTo(version) > 0.

Parameters:

public boolean isOlderOrEqualTo(ClickHouseVersion version)

Checks if the version is older or equal to the given one. Pay attention that when comparing "21.3.1.1" to "21.3", compareTo(ClickHouseVersion) says the former is greater, but this method will return true(because 21.3.x.x still belongs to 21.3 series).

Parameters:
