    • isReadOnly

      public boolean isReadOnly()
      Description copied from interface: IPObject
      All write attempts on read-only objects will end up with exception.

      Temporary objects are never read-only, even their fields, which are defined as read-only in prototype can be written to temporary objects (since they are likely needed during the creation).

      Specified by:
      isReadOnly in interface IPObject
      Returns:
      true is this object is read-only, false otherwise. There are several reasons for object to be read-only: it can be marked on prototype or recognized from the URL (which points to particular version of the object) or when the current transaction is read-only.

      public boolean isModified()
      Specified by:
      isModified in interface IPObject
      Returns:

    • isUnresolvable

      public boolean isUnresolvable()

      This method guarantees that the object is either resolved, or unresolvable.
      Specified by:
      isUnresolvable in interface IPObject

      false if this object is resolved. Returns true if attempt to resolve did fail. If this method returns true then all attempts to call get/set methods will result in exception.

    • isResolved

      public boolean isResolved()
      Specified by:
      isResolved in interface IPObject
      Returns:
      Returns true is data of this object are already loaded, false otherwise.

      Specified by:
      update in interface IPObject
      See Also:

    • forget

      public void forget()
      Description copied from interface: IPObject

    • adapt

      public Object adapt(Class targetClass)
      Specified by:
      adapt in interface IAdaptable
      Returns:
      The incance of targetClass representing this object or null if adaptation is not possible.

      equals in class Object

    • getDataSvc

      public IDataService getDataSvc()
      Description copied from interface: IPObject
      This is a convenience method, so that everyone, who has a IPObject in hand, can easily get the IDataService as well and doesn't have to do some additional work (since the IPObject has this reference anyway.
      Specified by:
      getDataSvc in interface IPObject
      Returns:
      The data service this object is bound to.

    • copyTo

      public void copyTo(@NotNull IPObject dest, @Nullable Set<String> includeKeys, @Nullable Set<String> excludeKeys, boolean includeAllCustomFields, @Nullable Set<String> notCopiedCustomFields, @Nullable Set<String> convertedCopiedCustomFields)
      Description copied from interface: IPObject
      Copies the content of this IPObject to a given IPObject.

      Both objects must be of the same prototype.

      New persistent objects may be created in the process.

      IPObject.save() may be called on any object (this object, the destination object or any new object) during the execution of this method. However the caller must call IPObject.save() on the destination object in order to make all changes persistent.

      The exact implementation is type-dependent.

      Specified by:
      copyTo in interface IPObject
      Parameters:
      dest - destination object (not null)
      includeKeys - which keys to include when copying (null means all); can also include custom keys
      excludeKeys - which keys to exclude when copying (null means none); can also include custom keys
      includeAllCustomFields - true if all custom fields should also be copied; if false then only those mentioned in includeKeys and not mentioned in excludeKeys are copied
      notCopiedCustomFields - custom fields that could not be copied (output); note that since 3.5.1 this is always an empty set, because the 'incompatibleCustomFields' feature is used for custom fields of this type
      convertedCopiedCustomFields - custom fields which were converted rather than exact copies (output). Since 3.5.1 this also includes incompatible custom fields.
