  +--com.bea.wlpi.common.VersionInfo

public final class VersionInfo

extends java.lang.Object

implements java.io.Serializable, java.lang.Comparable

Holds information about a version number. Objects of this class are available in both clients and server (via the ServerProperties session bean, and can be compared with each other to determine up/down level compatibility.

Objects of this class override the boolean equals(Object) and implement the comparable interface.

Constructor Detail

VersionInfo

public VersionInfo(int majorVersion,
                   int minorVersion,
                   java.lang.String build,
                   java.lang.String name)

Create a new VersionInfo object.

Parameters:

majorVersion - The major version number (e.g., the 1 in "1.2").

minorVersion - The minor version number (e.g., the 2 in "1.2").

build - The build number or name.

name - The release name (e.g. "Chicoutimi").

VersionInfo

public VersionInfo(int majorVersion,
                   int minorVersion,
                   int volume,
                   java.lang.String build,
                   java.lang.String name)

Create a new VersionInfo object.

Parameters:

majorVersion - The major version number (e.g., the 1 in "1.2").

minorVersion - The minor version number (e.g., the 2 in "1.2").

volume - The volume number (e.g., the 3 in "1.2.3"). Used only in volume releases.

build - The build number or name.

name - The release name (e.g. "Chicoutimi").

VersionInfo

public VersionInfo(java.lang.String version)

Create a new VersionInfo object from a string.

Parameters:

version - The version number expressed in Dewey Decimal format (e.g., "1.2.3"). The string can contain between two and four dot-separated integer components, corresponding to the majorVersion, minorVersion, volume, build values. If there are three such components, the third is interpreted as the volume number: to specify a build number, supply four tokens (the volume number can be 0).

Method Detail

getDefaultVersion

public static final VersionInfo getDefaultVersion()

Return the information about the first release of WebLogic Process Integrator.

Returns:

information for "1.0.0 Athabasca"

getMajorVersion

public final int getMajorVersion()

Return the major version number.

Returns:

The major version number as set by the constructor.

getMinorVersion

public final int getMinorVersion()

Return the minor version number.

Returns:

The minor version number as set by the constructor.

getVolume

public final int getVolume()

Return the volume number.

Returns:

The volume number as set by the constructor.

getBuild

public final java.lang.String getBuild()

Return the build number or name.

Returns:

The build number or name as set by the constructor.

getName

public final java.lang.String getName()

Return the release name.

Returns:

The release name as set by the constructor.

equals

public boolean equals(java.lang.Object obj)

Test two VersionInfo objects for equality. The comparison is based solely on the major and minor version numbers.

Parameters:

obj - Object with which to compare this one.

Returns:

true if obj is an instance of VersionInfo with the same majorVersion and minorVersion as this one.

Overrides:

equals in class java.lang.Object

compareTo(java.lang.Object)

compareTo

public int compareTo(java.lang.Object obj)

Compare two VersionInfo objects.

Specified by:

compareTo in interface java.lang.Comparable

Parameters:

obj - Object with which to compare this one.

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object. The result of detemined by comparing the majorVersion and minorVersion members of the two objects.

Throws:

java.lang.ClassCastException - if o is not an instance of VersionInfo.

equals(java.lang.Object)

toString

public java.lang.String toString()

Return a string representation of the object. The string contains the values of the majorVersion, minorVersion, volume and build members, separated by periods (e.g., "1.2.3 SP4"). Volume and build (i.e., Service Pack) are only shown if they are non-zero.

Returns:

the version number as a string.

Overrides:

toString in class java.lang.Object
