SVNRevision

public class SVNRevision (Code)

SVNRevision is a revision wrapper used for an abstract representation of revision information.

Most of high-level API classes' methods receive revision parameters as SVNRevision objects to get information on SVN revisions and use it in version control operations.

This class provides advantages of specifying revisions either as just long numbers or dated revisions (when a revision is determined according to a particular timestamp) or SVN compatible keywords denoting the latest revision (HEAD), Working Copy pristine revision (BASE) and so on. And one more feature is that SVNRevision can parse strings (that can be anything: string representations of numbers, dates, keywords) to construct an SVNRevision to use.
version:
1.1.1
author:
TMate Software Ltd.

Field Summary
final public static SVNRevision	BASE Denotes the 'pristine' revision of a Working Copy item.
final public static SVNRevision	COMMITTED Denotes the last revision in which an item was changed before (or at) BASE.
final public static SVNRevision	HEAD Denotes the latest repository revision.
final public static SVNRevision	PREVIOUS Denotes the revision just before the one when an item was last changed (technically, COMMITTED - 1).
final public static SVNRevision	UNDEFINED Used to denote that a revision is undefined (not available or not valid).
final public static SVNRevision	WORKING Denotes an item's working (current) revision.

Method Summary
public static SVNRevision	create(long revisionNumber) Creates an SVNRevision object given a revision number.
public static SVNRevision	create(Date date) Creates an SVNRevision object given a particular timestamp.
public boolean	equals(Object o) Compares this object with another SVNRevision object.
public Date	getDate() Gets the timestamp used to specify a revision.
public int	getID() Gets the identifier of the revision information kind this object represents.
public String	getName() Gets the revision keyword name.
public long	getNumber() Gets the revision number represented by this object.
public int	hashCode() Evaluates the hash code for this object.
public boolean	isLocal() Determines if the revision represented by this abstract object is Working Copy specific - that is one of SVNRevision.BASE or SVNRevision.WORKING .
public boolean	isValid() Checks if the revision information represented by this object is valid. SVNRevision.UNDEFINED is not a valid revision.
public static boolean	isValidRevisionNumber(long revision) Checks whether a revision number is valid.
public static SVNRevision	parse(String value) Parses an input string and be it a representation of either a revision number, or a timestamp, or a revision keyword, constructs an SVNRevision representation of the revision.
public String	toString() Gives a string representation of this object.

Field Detail

BASE
final public static SVNRevision BASE(Code)
	Denotes the 'pristine' revision of a Working Copy item. SVN's analogue keyword: BASE.

COMMITTED
final public static SVNRevision COMMITTED(Code)
	Denotes the last revision in which an item was changed before (or at) BASE. SVN's analogue keyword: COMMITTED.

HEAD
final public static SVNRevision HEAD(Code)
	Denotes the latest repository revision. SVN's analogue keyword: HEAD.

PREVIOUS
final public static SVNRevision PREVIOUS(Code)
	Denotes the revision just before the one when an item was last changed (technically, COMMITTED - 1). SVN's analogue keyword: PREV.

UNDEFINED
final public static SVNRevision UNDEFINED(Code)
	Used to denote that a revision is undefined (not available or not valid).

WORKING
final public static SVNRevision WORKING(Code)
	Denotes an item's working (current) revision. This is a SVNKit constant that should be provided to mean working revisions (what the native SVN client assumes by default).

Method Detail

create
public static SVNRevision create(long revisionNumber)(Code)
	Creates an SVNRevision object given a revision number. Parameters: revisionNumber - a definite revision number the constructed SVNRevision object

create
public static SVNRevision create(Date date)(Code)
	Creates an SVNRevision object given a particular timestamp. Parameters: date - a timestamp represented as a Date instance the constructed SVNRevision object

equals
public boolean equals(Object o)(Code)
	Compares this object with another SVNRevision object. Parameters: o - an object to be compared with; if it's not an SVNRevision then this method certainly returnsfalse true if equal, otherwisefalse

getDate
public Date getDate()(Code)
	Gets the timestamp used to specify a revision. a timestamp if any specified for this object

getID
public int getID()(Code)
	Gets the identifier of the revision information kind this object represents. this object's id

getName
public String getName()(Code)
	Gets the revision keyword name. Each of SVNRevision's constant fields that represent revision keywords also have its own name. a revision keyword name

getNumber
public long getNumber()(Code)
	Gets the revision number represented by this object. a revision number; -1 is returned when this object represents a revision information not using a revision number.

hashCode
public int hashCode()(Code)
	Evaluates the hash code for this object. A hash code is evaluated in this way: if this object represents revision info as a revision number then `hash code = (int) revisionNumber & 0xFFFFFFFF`; if this object represents revision info as a timestamp then java.util.Date.hashCode is used; if this object represents revision info as a keyword then java.lang.String.hashCode is used for the keyword name; this object's hash code

isLocal
public boolean isLocal()(Code)
	Determines if the revision represented by this abstract object is Working Copy specific - that is one of SVNRevision.BASE or SVNRevision.WORKING . true if this object represents a kind of a local revision, otherwise false

isValid
public boolean isValid()(Code)
	Checks if the revision information represented by this object is valid. SVNRevision.UNDEFINED is not a valid revision. true if valid, otherwisefalse

isValidRevisionNumber
public static boolean isValidRevisionNumber(long revision)(Code)
	Checks whether a revision number is valid. Parameters: revision - a revision number true if valid, otherwise false

parse
public static SVNRevision parse(String value)(Code)
	Parses an input string and be it a representation of either a revision number, or a timestamp, or a revision keyword, constructs an SVNRevision representation of the revision. Parameters: value - a string to be parsed an SVNRevision object that holds the revisioninformation parsed from `value`; howeverif an input string is not a valid one which can besuccessfully transformed to an SVNRevision thereturn value is SVNRevision.UNDEFINED

toString
public String toString()(Code)
	Gives a string representation of this object. a string representing this object
