Class DomainFileProxy

java.lang.Object
ghidra.framework.data.DomainFileProxy
All Implemented Interfaces:
DomainFile, Comparable<DomainFile>
public class DomainFileProxy extends Object implements DomainFile
Implements the DomainFile interface for DomainObjects that are not currently associated with any real DomainFile. This class enforces the sharing of objects between tools. After the first tool gets the implementation, all other gets() just get the same instance. This class also keeps track of which tools are using a its domain object.

  • Method Details

    • exists

      public boolean exists()
      Description copied from interface: DomainFile
      Check for existence of domain file.
      Specified by:
      exists in interface DomainFile
      Returns:
      true if file exists. A proxy domain file will always return false.

    • setName

      public DomainFile setName(String newName)
      Description copied from interface: DomainFile
      Set the name on this domain file.
      Specified by:
      setName in interface DomainFile
      Parameters:
      newName - domain file name
      Returns:
      renamed domain file (the original DomainFile object becomes invalid since it is immutable)

    • getProjectLocator

      public ProjectLocator getProjectLocator()
      Description copied from interface: DomainFile
      Returns the local storage location for the project that this DomainFile belongs to.

      getProjectLocator in interface DomainFile
      Returns:
      the location

    • length

      public long length() throws IOException
      Description copied from interface: DomainFile
      Returns the length of this domain file. This size is the minimum disk space used for storing this file, but does not account for additional storage space used to track changes, etc.

      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exception will be thrown if the domain object cannot be upgraded OR okToUpgrade is false and the domain object is out of date.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.

    • getImmutableDomainObject

      public DomainObject getImmutableDomainObject(Object consumer, int fileVersion, TaskMonitor monitor) throws VersionException, IOException, CancelledException
      Description copied from interface: DomainFile
      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).
      Specified by:
      getImmutableDomainObject in interface DomainFile
      Parameters:
      consumer - consumer of the domain object which is responsible for releasing it after use.
      fileVersion - 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.
      IOException - if an IO or access error occurs.
      CancelledException - if monitor cancelled operation

    • getReadOnlyDomainObject

      public DomainObject getReadOnlyDomainObject(Object consumer, int fileVersion, TaskMonitor monitor) throws VersionException, IOException, CancelledException
      Description copied from interface: DomainFile
      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.
      Specified by:
      getReadOnlyDomainObject in interface DomainFile
      Parameters:
      consumer - consumer of the domain object which is responsible for releasing it after use.
      fileVersion - 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.
      IOException - if an IO or access error occurs.
      CancelledException - if monitor cancelled operation
