méthodes

Signature	Description
`NameTree(root: PdfDictionary)`	Wraps the given root dictionary.
`getRoot()` → `PdfDictionary`	Returns the underlying root dictionary, or {@code null} if this view
was constructed over a {@code null} root.
`isEmpty()` → `boolean`	Returns whether the tree has no entries.
`size()` → `int`	Returns the number of (key, value) pairs in the tree.
`get(key: String)` → `PdfBase`	Looks up a key.
`containsKey(key: String)` → `boolean`	Returns whether the tree contains the given key.
`entries()` → `List<Map.Entry<String, PdfBase>>`	Returns all entries in tree order (which, for a conformant tree, is
key-sorted order).
`keys()` → `List<String>`	Returns all keys in tree order.
`put(key: String, value: PdfBase)` → `PdfBase`	Inserts or replaces a value.
`remove(key: String)` → `PdfBase`	Removes a key.
`clear()`	Empties the tree: drops all {@code /Kids}, {@code /Limits} and any
{@code /Names} array contents.
`entriesUnmodifiable()` → `List<Map.Entry<String, PdfBase>>`	Returns an unmodifiable view of {@link #entries()} for callers that
want a {@link List} interface but no mutation.
