|
||
// a unique object identifier by which other objects can refer to it (for example, as an
|
||
// element of an array or as the value of a dictionary entry). The object identifier
|
||
// consists of two parts:
|
||
// * A positive integer object number. Indirect objects are often numbered sequentially
|
||
// within a PDF file, but this is not required; object numbers may be
|
||
// assigned in any arbitrary order.
|
||
// * A non-negative integer generation number. In a newly created file, all indirect
|
||
// objects have generation numbers of 0. Nonzero generation numbers may be introduced
|
||
// when the file is later updated; see Sections 3.4.3, <20>Cross-Reference
|
||
// Table,<2C> and 3.4.5, <20>Incremental Updates.<2E>
|
||
// Together, the combination of an object number and a generation number uniquely
|
||
// identifies an indirect object. The object retains the same object number and
|
||
// generation number throughout its existence, even if its value is modified.
