## Detailed Description

knows all currently used and all free numbers for using with untitled but counted objects.

## Member Function Documentation

## ◆ getUntitledPrefix()

string getUntitledPrefix | ( |  | ) |

returns the localized string value to be used for untitled objects in combination with the leased number.

Note: Such string already contains leading spaces/tabs etc. ! The only thing which an outside code has todo then ... adding a leased number to the string.

Returns
  the localized string for untitled components.

## ◆ leaseNumber()

long leaseNumber | ( | [in] com::sun::star::uno::XInterface | xComponent | ) |
raises | ( | com::sun::star::lang::IllegalArgumentException
| ) |  |

callee has to lease a number before he can use it within in its own title.

Such number must be freed after using e.g. while the object was closed or gets another title (e.g. by saving a document to a real location on disc).

Parameters

  xComponent | the component which has to be registered for the leased number.

Returns
  the new number for these object or 0 if no further numbers are available.

Exceptions

  [IllegalArgumentException] | if an invalid object reference was provided to this method.

## ◆ releaseNumber()

void releaseNumber | ( | [in] long | nNumber | ) |
raises | ( | com::sun::star::lang::IllegalArgumentException
| ) |  |

has to be used to mark those numbers as "free for using".

If the registered component does not use such leased number any longer it has to be released so it can be used for new components.

Note: calling this method with an unknown (but normally valid number) has to be ignored. No exceptions - no errors.

Parameters

  nNumber | specify number for release.

Exceptions

  [IllegalArgumentException] | if the given number is the special value 0.

## ◆ releaseNumberForComponent()

void releaseNumberForComponent | ( | [in] com::sun::star::uno::XInterface | xComponent | ) |
raises | ( | com::sun::star::lang::IllegalArgumentException
| ) |  |

does the same then releaseNumber () but it searches the corresponding number for the specified component and deregister it.

Parameters

  xComponent | the component for deregistration.

Exceptions

  [IllegalArgumentException] | if an invalid object reference was provided to this method.
