createFile
public long createFile(FileSystem fs, FileSystem userfs, String path, String name, DomainObject obj, TaskMonitor monitor) throws IOException, InvalidNameException, CancelledException Description copied from interface:ContentHandler
Creates a new folder item within a specified file-system. If fs is versioned, the resulting item is marked as checked-out within the versioned file-system. The specified domainObj will become associated with the newly created database.- Parameters:
fs

- the name of the new folder itemobj
- the domain object to store in the newly created folder itemmonitor
- the monitor that allows the user to cancel- Returns:
- checkout ID for new item
- Throws:
IOException
- if an IO error occurs or an unsupporteddomainObject
implementation is specified.InvalidNameException
- if the specified name contains invalid charactersCancelledException
- if the user cancels
-

- consumer of the returned objectversion
- version of the stored folder item to be opened. DomainFile.DEFAULT_VERSION (-1) should be specified when not opening a specific file version.minChangeVersion
- the minimum version which should be included in the change set for the returned object. A value of -1 indicates the default change set.monitor
- the monitor that allows the user to cancel- Returns:
- immutable domain object
- Throws:
IOException
- if an IO or folder item access error occursVersionException
- if unable to handle file content due to version difference which could not be handled.CancelledException
- if operation is cancelled by user
-
getReadOnlyObject
public DataTypeArchiveDB getReadOnlyObject(FolderItem item, int version, boolean okToUpgrade, Object consumer, TaskMonitor monitor) throws IOException, VersionException, CancelledException Description copied from interface:ContentHandler
Open a folder item for read-only use. While changes are permitted on the returned object, the original folder item may not be overwritten / updated.- Parameters:
item
- stored folder itemversion
- version of the stored folder item to be opened. DomainFile.DEFAULT_VERSION should be specified when not opening a specific file version.okToUpgrade
- if true a version upgrade to the content will be done if necessary.consumer
- consumer of the returned objectmonitor
- the monitor that allows the user to cancel- Returns:
- read-only domain object
- Throws:
IOException
- if an IO or folder item access error occursVersionException
- if unable to handle file content due to version difference which could not be handled.CancelledException
- if operation is cancelled by user
-
getDomainObject
public DataTypeArchiveDB getDomainObject(FolderItem item, FileSystem userfs, long checkoutId, boolean okToUpgrade, boolean recover, Object consumer, TaskMonitor monitor) throws IOException, VersionException, CancelledException Description copied from interface:ContentHandler
Open a folder item for update. Changes made to the returned object may be saved to the original folder item.- Parameters:
item
- stored folder itemuserfs
- file system which contains associated user datacheckoutId
- an appropriate checout ID required to update the specified folder item.okToUpgrade
- if true a version upgrade to the content will be done if necessary.recover
- if true an attempt to recover any unsaved changes resulting from a crash will be attempted.consumer
- consumer of the returned objectmonitor
- cancelable task monitor- Returns:
- updateable domain object
- Throws:
IOException
- if an IO or folder item access error occursVersionException
- if unable to handle file content due to version difference which could not be handled.CancelledException
- if operation is cancelled by user
-
getChangeSet
public ChangeSet getChangeSet(FolderItem item, int fromVer, int toVer) throws VersionException, IOException Description copied from interface:ContentHandler
Returns the object change data which includes changes made to the specified olderVersion through to the specified newerVersion.- Parameters:
item
- versioned folder itemfromVer
- the older version numbertoVer
- the newer version number- Returns:
- the set of changes that were made
- Throws:
VersionException
- if a database version change prevents reading of data.IOException
- if an IO or folder item access error occurs or change set was produced by newer version of software and can not be read

canResetDBSourceFile
public boolean canResetDBSourceFile()Description copied from interface:ContentHandler
Determine if this content handler supports the use ofContentHandler.resetDBSourceFile(FolderItem, DomainObjectAdapterDB)
.A versioned
domain object
open for update may have its underlying database reset to the latest buffer file version:- The
ContentHandler.resetDBSourceFile(FolderItem, DomainObjectAdapterDB)
method is invoked (synchronized on filesystem) to reset the underlying database source file and and any corresponding change sets held by the specified domain object to the latest version, - afterwhich the caller must
invalidate
the domain object instance which will clear all caches and generate aDomainObjectEvent.RESTORED
event.
- Returns:
- true if this content handler supports DB source file replacement, else false
- The
-
resetDBSourceFile
Description copied from interface:ContentHandler
Reset the database for the specified domain object to its latest buffer file version. It is very important that the specified folder item matches the item which was used to originally open the specified domain object. This method should be invoked with a filesystem lock.Following the invocation of this method, the specified domain object should be
invalidated
without a filesystem lock.- Parameters:
item
- local versioned database folder item currently checked-out. An error will be thrown if not an instanceof LocalDatabaseItem. This should always be the case for an item which has just processed a versioning action with a retained checkout (e.g., checkin, merge, add-to-version-control).domainObj
- domain object which is currently open for update- Throws:
IOException
- if an IO error occurs
