org.tmatesoft.svn.core.wc.SVNRevision
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 1.3 @author TMate Software Ltd. @since 1.2
