Struct CrossRefTable 

pub struct CrossRefTable { /* private fields */ }

Cross-reference table that maps object numbers to their locations.

Implementations

impl CrossRefTable

pub fn new() -> Self

Create a new empty cross-reference table.

pub fn set_trailer(&mut self, trailer: HashMap<String, Object>)

Set the trailer dictionary.

pub fn trailer(&self) -> Option<&HashMap<String, Object>>

Get the trailer dictionary if present.

pub fn add_entry(&mut self, object_number: u32, entry: XRefEntry)

Add an entry to the cross-reference table.

pub fn get(&self, object_number: u32) -> Option<&XRefEntry>

Get an entry by object number.

pub fn contains(&self, object_number: u32) -> bool

Check if an object exists in the xref table.

pub fn all_object_numbers(&self) -> impl Iterator<Item = u32> + '_

Get all object numbers in the table.

pub fn merge_from(&mut self, other: CrossRefTable)

Merge entries from another xref table.

Entries in self override entries in other (for incremental updates). This is used when following /Prev pointers in the trailer.

pub fn len(&self) -> usize

Get the number of entries in the table.

pub fn is_empty(&self) -> bool

Check if the table is empty.
