Class FileSystemSource

java.lang.Object
  org.modeshape.graph.connector.path.AbstractPathRepositorySource
      org.modeshape.connector.filesystem.FileSystemSource

All Implemented Interfaces:

Serializable, Referenceable, ObjectFactory, PathRepositorySource, RepositorySource

@ThreadSafe
public class FileSystemSource
extends AbstractPathRepositorySource
implements ObjectFactory

The RepositorySource for the connector that exposes an area of the local file system as content in a repository. This source considers a workspace name to be the path to the directory on the file system that represents the root of that workspace. New workspaces can be created, as long as the names represent valid paths to existing directories.

Constructor Detail

FileSystemSource

public FileSystemSource()

Method Detail

getCapabilities

public RepositorySourceCapabilities getCapabilities()

Get the capabilities for this source.

Specified by:

getCapabilities in interface RepositorySource

Returns:

the capabilities for this source; never null

See Also:

RepositorySource.getCapabilities()

getUpdatesAllowed

public boolean getUpdatesAllowed()

Get whether this source supports updates.

Returns:

true if this source supports updates, or false if this source only supports reading content.

getWorkspaceRootPath

public String getWorkspaceRootPath()

Get the relative root directory for the workspaces. If this property is set, workspaces can be given as relative paths from this directory and all workspace paths must be ancestors of this path.

Returns:

the root directory for workspaces

setWorkspaceRootPath

public void setWorkspaceRootPath(String workspaceRootPath)

Sets the relative root directory for workspaces

Parameters:

workspaceRootPath - the relative root directory for workspaces. If this value is non-null, all workspace paths will be treated as paths relative to this directory

getExclusionPattern

public String getExclusionPattern()

Get the regular expression that, if matched by a file or folder, indicates that the file or folder should be ignored

Returns:

the regular expression that, if matched by a file or folder, indicates that the file or folder should be ignored

setExclusionPattern

public void setExclusionPattern(String exclusionPattern)

Sets the regular expression that, if matched by a file or folder, indicates that the file or folder should be ignored

Parameters:

exclusionPattern - the regular expression that, if matched by a file or folder, indicates that the file or folder should be ignored. If this pattern is null, no files will be excluded.

getMaxPathLength

public int getMaxPathLength()

Get the maximum path length (in characters) allowed by the underlying file system

Returns:

the maximum path length (in characters) allowed by the underlying file system

setMaxPathLength

public void setMaxPathLength(int maxPathLength)

Set the maximum absolute path length supported by this source.

The length of any path is calculated relative to the file system root, NOT the repository root. That is, if a workspace foo is mapped to the /tmp/foo/bar directory on the file system, then the path /node1/node2 in the foo workspace has an effective length of 23 for the purposes of the maxPathLength calculation (/tmp/foo/bar has length 11, /node1/node2 has length 12, 11 + 12 = 23).

Parameters:

maxPathLength - the maximum absolute path length supported by this source; must be non-negative

getDefaultWorkspaceName

public String getDefaultWorkspaceName()

Get the name of the default workspace.

Specified by:

getDefaultWorkspaceName in interface PathRepositorySource

Returns:

the name of the workspace that should be used by default; never null

setDefaultWorkspaceName

public void setDefaultWorkspaceName(String nameOfDefaultWorkspace)

Set the name of the workspace that should be used when clients don't specify a workspace.

Parameters:

nameOfDefaultWorkspace - the name of the workspace that should be used by default, or null if the default name should be used

getPredefinedWorkspaceNames

public String[] getPredefinedWorkspaceNames()

Gets the names of the workspaces that are available when this source is created. Each workspace name corresponds to a path to a directory on the file system.

Returns:

the names of the workspaces that this source starts with, or null if there are no such workspaces

See Also:

setPredefinedWorkspaceNames(String[]), setCreatingWorkspacesAllowed(boolean)

setPredefinedWorkspaceNames

public void setPredefinedWorkspaceNames(String[] predefinedWorkspaceNames)

See Also:

setCreatingWorkspacesAllowed(boolean), getPredefinedWorkspaceNames()

isCreatingWorkspacesAllowed

public boolean isCreatingWorkspacesAllowed()

Get whether this source allows workspaces to be created dynamically.

Returns:

true if this source allows workspaces to be created by clients, or false if the set of workspaces is fixed

See Also:

setPredefinedWorkspaceNames(String[]), getPredefinedWorkspaceNames(), setCreatingWorkspacesAllowed(boolean)

setCreatingWorkspacesAllowed
