## org.tmatesoft.svn.core.wc
Class SVNBasicClient

    java.lang.Object
      org.tmatesoft.svn.core.wc.SVNBasicClient

All Implemented Interfaces:
  ISVNCanceller, ISVNEventHandler

Direct Known Subclasses:
  SVNAdminClient, SVNChangelistClient, SVNCommitClient, org.tmatesoft.svn.core.internal.wc.SVNCopyDriver, SVNLogClient, SVNLookClient, org.tmatesoft.svn.core.internal.wc.SVNMergeDriver, SVNStatusClient, SVNUpdateClient, SVNWCClient

public class SVNBasicClient
extends Object
implements ISVNEventHandler

The SVNBasicClient is the base class of all SVN*Client classes that provides a common interface and realization.

All of SVN*Client classes use inherited methods of SVNBasicClient to access Working Copies metadata, to create a driver object to access a repository if it's necessary, etc. In addition SVNBasicClient provides some interface methods - such as those that allow you to set your `event handler`, obtain run-time configuration options, and others.

Since:
  1.2

Constructor Detail

### SVNBasicClient

    protected SVNBasicClient(ISVNAuthenticationManager authManager,
                             ISVNOptions options)

### SVNBasicClient

    protected SVNBasicClient(ISVNRepositoryPool repositoryPool,
                             ISVNOptions options)

Method Detail

### getOptions

    public ISVNOptions getOptions()

  Gets run-time configuration options used by this object.

  Returns:
    the run-time options being in use

### setOptions

    public void setOptions(ISVNOptions options)

  Sets run-time global configuration options to this object.

  Parameters:
    `options` - the run-time configuration options

### setIgnoreExternals

    public void setIgnoreExternals(boolean ignore)

  Sets externals definitions to be ignored or not during operations.

  For example, if external definitions are set to be ignored then a checkout operation won't fetch them into a Working Copy.

  Parameters:
    `ignore` - true to ignore externals definitions, false - not to
  See Also:
    `isIgnoreExternals()`

### isIgnoreExternals

    public boolean isIgnoreExternals()

  Determines if externals definitions are ignored.

  Returns:
    true if ignored, otherwise false
  See Also:
    `setIgnoreExternals(boolean)`

### setLeaveConflictsUnresolved

    public void setLeaveConflictsUnresolved(boolean leave)

  Deprecated. this method should not be used anymore

  Sets (or unsets) all conflicted working files to be untouched by update and merge operations.

  By default when a file receives changes from the repository that are in conflict with local edits, an update operation places two sections for each conflicting snatch into the working file one of which is a user's local edit and the second is the one just received from the repository. Like this:

       <<<<<<< .mine
       user's text
       =======
       received text
       >>>>>>> .r2

  Also the operation creates three temporary files that appear in the same directory as the working file. Now if you call this method with `leave` set to true, an update will still create temporary files but won't place those two sections into your working file. And this behaviour also concerns merge operations: any merging to a conflicted file will be prevented. In addition if there is any registered event handler for an SVNDiffClient or SVNUpdateClient instance then the handler will be dispatched an event with the status type set to `SVNStatusType.CONFLICTED_UNRESOLVED`.

  The default value is false until a caller explicitly changes it calling this method.

  Parameters:
    `leave` - true to prevent conflicted files from merging (all merging operations will be skipped), otherwise false
  See Also:
    `isLeaveConflictsUnresolved()`, `SVNUpdateClient`, `SVNDiffClient`, `ISVNEventHandler`

### isLeaveConflictsUnresolved

    public boolean isLeaveConflictsUnresolved()

  Deprecated. this method should not be used anymore

  Determines if conflicted files should be left unresolved preventing from merging their contents during update and merge operations.

  Returns:
    true if conflicted files are set to be prevented from merging, false if there's no such restriction
  See Also:
    `setLeaveConflictsUnresolved(boolean)`

### setEventHandler

    public void setEventHandler(ISVNEventHandler dispatcher)

  Sets an event handler for this object. This event handler will be dispatched `SVNEvent` objects to provide detailed information about actions and progress state of version control operations performed by do*() methods of SVN*Client classes.

  Parameters:
    `dispatcher` - an event handler

### setPathListHandler

    public void setPathListHandler(ISVNPathListHandler handler)

  Sets a path list handler implementation to this object.

  Parameters:
    `handler` - handler implementation
  Since:
    1.2.0

### setDebugLog

    public void setDebugLog(org.tmatesoft.svn.util.ISVNDebugLog log)

  Sets a logger to write debug log information to.

  Parameters:
    `log` - a debug logger

### getDebugLog

    public org.tmatesoft.svn.util.ISVNDebugLog getDebugLog()

  Returns the debug logger currently in use.

  If no debug logger has been specified by the time this call occurs, a default one (returned by `org.tmatesoft.svn.util.SVNDebugLog.getDefaultLog()`) will be created and used.

  Returns:
    a debug logger

### getReposRoot

    public SVNURL getReposRoot(File path,
                               SVNURL url,
                               SVNRevision pegRevision,
                               org.tmatesoft.svn.core.internal.wc.admin.SVNAdminArea adminArea,
                               org.tmatesoft.svn.core.internal.wc.admin.SVNWCAccess access)
                        throws SVNException

  Returns the root of the repository.

  If `path` is not null and `pegRevision` is either `SVNRevision.WORKING` or `SVNRevision.BASE`, then attempts to fetch the repository root from the working copy represented by `path`. If these conditions are not met or if the repository root is not recorded in the working copy, then a repository connection is established and the repository root is fetched from the session.

  When fetching the repository root from the working copy and if `access` is null, a new working copy access will be created and the working copy will be opened non-recursively for reading only.

  All necessary cleanup (session or|and working copy close) will be performed automatically as the routine finishes.

  Parameters:
    `path` - working copy path
    `url` - repository url
    `pegRevision` - revision in which the target is valid
    `adminArea` - working copy administrative area object
    `access` - working copy access object
  Returns:
    repository root url
  Throws:
    `SVNException`
  Since:
    1.2.0
