Class SVNEvent

java.lang.Object

org.tmatesoft.svn.core.wc.SVNEvent

Direct Known Subclasses:

SVNEventExt

public class SVNEvent
extends Object

The SVNEvent class is used to provide detailed information on an operation progress to the ISVNEventHandler (if any) registered for an SVN*Client object. Such events are generated by an operation invoked by do*() method of an SVN*Client object and passed to a developer's event handler for notification. Retrieving information out of an SVNEvent the developer can decide how it should be interpreted.

This is an example:
implementing ISVNEventHandler

 import org.tmatesoft.svn.core.wc.ISVNEventHandler;
 import org.tmatesoft.svn.core.SVNCancelException;
 import org.tmatesoft.svn.core.wc.SVNEvent;
 import org.tmatesoft.svn.core.wc.SVNEventAction;
 import org.tmatesoft.svn.core.wc.SVNStatusType;
 import org.tmatesoft.svn.core.SVNNodeKind;
 import java.io.File;
 ...
 
 public class MyCustomUpdateEventHandler implements ISVNEventHandler {
     public void handleEvent(SVNEvent event, double progress) {
         //get the action type
         if(event.getAction() == SVNEventAction.UPDATE_UPDATE){
             //get the item's node kind
             SVNNodeKind kind = even.getNodeKind();
             //get the item's contents status
             if(event.getContentsStatus() == SVNStatusType.CHANGED &&
                kind == SVNNodeKind.FILE){
                 ...
             }
             ...
             //get the item's properties status
             if(event.getPropertiesStatus() == SVNStatusType.MERGED){
                 ...
             }
             //get the item's lock status
             if(event.getLockStatus() == SVNStatusType.LOCK_UNLOCKED){
                 ...
             }
             //get the item's relative path
             String path = event.getPath();
             //or in a java.io.File representation
             File fsEntry = event.getFile(); 
             
             //get update revision
             long revision = event.getRevision(); 
             ...
         }
         ...
     }
     
     public void checkCancelled() throws SVNCancelException{
         throw new SVNCancelException("cancelled!");
     }
 }

then registering a handler:

 import org.tmatesoft.svn.core.wc.SVNUpdateClient;
 ...
 
 SVNUpdateClient updateClient;
 ...
 updateClient.setEventHandler(new MyCustomUpdateEventHandler());
 ...

now when invoking an update operation:

 updateClient.doUpdate(...);

the registered instance of the ISVNEventHandler implementation will be dispatched progress events.

Constructor Detail

SVNEvent

public SVNEvent(SVNErrorMessage errorMessage,
                SVNEventAction expected)

Constructs an SVNEvent object given an error message for a filed operation.

Used by SVNKit internals to construct and initialize an SVNEvent object. It's not intended for users (from an API point of view).

Parameters:

errorMessage - the message describing the operation fault

mimetype - the item's MIME type

cstatus - the item's contents status

pstatus - the item's properties status

Method Detail

getFile

public File getFile()

Returns local path the event is fired for.

Returns:

local path

getAction

public SVNEventAction getAction()

Gets the type of an action performed upon the item. An action is one of predefined SVNEventAction constants that are specific for each kind of operation, such as update actions, commit actions, etc.

Returns:

the current action

getExpectedAction

public SVNEventAction getExpectedAction()

Returns the expected action. It is always the same as the action returned by getAction() except those cases when getAction() returns SVNEventAction.SKIP (i.e. when the expected operation is skipped).

Returns:

the expected action

getContentsStatus

public SVNStatusType getContentsStatus()

Gets the status type of either file or directory contents. Use predefined SVNStatusType constants to examine the item's status. For a directory contents are its entries.

Returns:

the item's status type

getErrorMessage

public SVNErrorMessage getErrorMessage()

Gets the error message that (if it's an error situation and therefore the string is not null) points to some fault.

Returns:

an error message (in case of an error occured) or null if everything is OK

getLock

public SVNLock getLock()

Gets the file item's lock information (if any) represented by an SVNLock object.

Returns:

the file item's lock info if the file is locked; otherwise null

getLockStatus

public SVNStatusType getLockStatus()

Gets the file item's lock status. The value of SVNStatusType.LOCK_INAPPLICABLE means the lock status is irrelevant during the current event action.

Returns:

the lock status of the file item

getMimeType

public String getMimeType()

Gets the MIME type of the item relying upon the special SVN's 'svn:mime-type' property.

You can use SVNProperty's metods to find out whether it's a text MIME type or a binary:

 import org.tmatesoft.svn.core.SVNProperty;
 ...
 
 String mimeType = event.getMimeType();
 if(SVNProperty.isBinaryMimeType(mimeType)){
     //your processing
 }

Returns:

the item's MIME type as a string or null if the item has no 'svn:mime-type' property set

getNodeKind

public SVNNodeKind getNodeKind()

Gets the node kind of the item characterizing it as an entry - whether it's a directory, file, etc. The value of SVNNodeKind.NONE may mean the node kind is inapplicable diring the current event action. The value of SVNNodeKind.UNKNOWN may mean deleted entries.

Returns:

the item's node kind

getPropertiesStatus

public SVNStatusType getPropertiesStatus()

Gets the status type of the item's properties. The value of SVNStatusType.INAPPLICABLE may mean the item has no versioned properties or that properties status is irrelevant during the current event action.

Returns:

the status type of the item's properties

getRevision

public long getRevision()

Gets the revision number specific for the action context. It may be whether an update revision or a committed one or an inapplicable value when a revision number is irrelevant during the event action.

Returns:

a revision number

getPreviousRevision

public long getPreviousRevision()

Returns the local revision before it will be changed by an update.

Returns:

revision prior to modification

Since:

getURL

public SVNURL getURL()

Returns the repository URL that this event is fired for.

Returns:

repository url

getPreviousURL

public SVNURL getPreviousURL()

Returns the item's repository url before it will be changed by an update.

Returns:

repository url prior to modification

Since:

1.2.0, SVN 1.5.0

public String getChangelistName()

Returns a changelist name. Relevant for changelist operations provided by SVNChangelistClient.

Returns:

changelist name

Since:

1.2.0, SVN 1.5.0

getMergeRange
