public interface DomainFile extends Comparable<DomainFile>
DomainFile provides a storage interface for project files. A DomainFile is an immutable reference to file contained within a project. The state of a DomainFile object does not track name/parent changes made to the referenced project file.

  • Field Details

    • UNSUPPORTED_FILE_ICON

      static final Icon UNSUPPORTED_FILE_ICON

    • DEFAULT_VERSION

      static final int DEFAULT_VERSION
      Use with getDomainObject to request the default version. The default version is the private file or check-out file if one exists, or the latest version from the version controlled file system.

      Set the name on this domain file.
      Parameters:
      newName - domain file name
      Returns:
      renamed domain file (the original DomainFile object becomes invalid since it is immutable)
      Throws:
      InvalidNameException - if newName contains illegal characters

    • getSharedProjectURL

      URL getSharedProjectURL(String ref)
      Get a remote Ghidra URL for this domain file if available within an associated shared project repository. A null value will be returned if shared file does not exist and may also be returned if shared repository is not connected or a connection error occurs.

      IOException - if a folder item access error occurs or change set was produced by newer version of software and can not be read

    • getDomainObject

      DomainObject getDomainObject(Object consumer, boolean okToUpgrade, boolean okToRecover, TaskMonitor monitor) throws VersionException, IOException, CancelledException
      Opens and returns the current domain object. If the domain object is already opened, then the existing open domain object is returned.
      Parameters:
      consumer - consumer of the domain object which is responsible for releasing it after use. When all the consumers using the domain object release it, then the object is closed and its resources released.
      okToUpgrade - if true, allows the system to upgrade out of data domain objects to be in compliance with the current version of Ghidra. A Version exception will be thrown if the domain object cannot be upgraded OR okToUpgrade is false and the domain object is out of date.
      okToRecover - if true, allows the system to recover unsaved file changes which resulted from a crash. If false, any existing recovery data will be deleted. This flag is only relevant if project is open for update (isInProject) and the file can be opened for update.
      monitor - permits monitoring of open progress.
      Returns:
      an open domain object can be modified and saved. (Not read-only)
      Throws:
      VersionException - if the domain object could not be read due to a version format change. If okToUpgrade is true, then a VersionException indicates that the domain object cannot be upgraded to the current format. If okToUpgrade is false, then the VersionException only means the object is not in the current format - it may or may not be possible to upgrade.
      IOException - if an IO or access error occurs.
      CancelledException - if monitor cancelled operation

    • getOpenedDomainObject

      DomainObject getOpenedDomainObject(Object consumer)
      Returns the domainObject for this DomainFile only if it is already open.
      Parameters:
      consumer - the consumer that will use the object.
      Returns:
      the already opened domainObject or null if it is not currently open.

    • getReadOnlyDomainObject

      DomainObject getReadOnlyDomainObject(Object consumer, int version, TaskMonitor monitor) throws VersionException, IOException, CancelledException
      Returns a "read-only" version of the domain object. "Read-only" means that the domain object cannot be saved back into its original domain object. It can still be modified and saved to a new domain file. The domain object will be assigned a temporary domain file that will not allow a "save" operation. The user must do a "save as" to a new filename.
      Parameters:
      consumer - consumer of the domain object which is responsible for releasing it after use.
      version - the domain object version requested. DEFAULT_VERSION should be specified to open the current version.
      monitor - permits monitoring of open progress.
      Returns:
      a new domain object that is disassociated from its original domain file.
      Throws:
      VersionException - if the domain object could not be read due to a version format change.
      FileNotFoundException - if the stored file/version was not found.
      IOException - if an IO or access error occurs.
      CancelledException - if monitor cancelled operation

    • getImmutableDomainObject

      DomainObject getImmutableDomainObject(Object consumer, int version, TaskMonitor monitor) throws VersionException, IOException, CancelledException
      Returns a new DomainObject that cannot be changed or saved to its original file. NOTE: The use of this method should generally be avoided since it can't handle version changes that may have occured and require a data upgrade (e.g., DB schema change).
      Parameters:
      consumer - consumer of the domain object which is responsible for releasing it after use.
      version - the domain object version requested. DEFAULT_VERSION should be specified to open the current version.
      monitor - permits monitoring of open progress.
      Returns:
      a new domain object that is disassociated from its original domain file and cannot be modified
      Throws:
      VersionException - if the domain object could not be read due to a version format change.
      FileNotFoundException - if the stored file/version was not found.
      IOException - if an IO or access error occurs.
      CancelledException - if monitor cancelled operation

    • save

      Parameters:
      monitor - monitor for the task that is doing the save on the file
      Throws:
      FileInUseException - if the file is open for update by someone else, or a transient-read is in progress.

      Returns:
      true if recovery data exists.

    • takeRecoverySnapshot

      boolean takeRecoverySnapshot() throws IOException
      If the file has an updatable domain object with unsaved changes, generate a recovery snapshot.
      Returns:
