méthodes

Signature	Description
`OperatorCollection(operators: List<Operator>)`	Creates a collection from an existing list of operators.
`OperatorCollection()`	Creates an empty operator collection.
`size()` → `int`	Returns the number of operators in this collection.
`get(index: int)` → `Operator`	Returns the operator at the given 1-based position
(Aspose-style indexing — {@code ops.get(1)} is the first operator).
`getAt(index: int)` → `Operator`	Returns the operator at the given 0-based position.
`setAt(index: int, op: Operator)`	Engine-side 0-based setter; pair with {@link #getAt(int)}.
`removeAt(index: int)`	Engine-side 0-based remove; pair with {@link #getAt(int)}.
`addAt(index: int, op: Operator)`	Engine-side 0-based insert; pair with {@link #getAt(int)}.
`add(op: Operator)`	Appends an operator to the end of this collection.
`add(other: java.util.Collection<? extends Operator>)`	Appends every operator from {@code other} to this collection.
`set(index: int, op: Operator)`	Replaces the operator at the specified 1-based index.
`insert(index: int, op: Operator)`	Inserts an operator at the specified 1-based index.
`delete(index: int)`	Removes the operator at the specified 1-based index.
`delete(toDelete: java.util.List<Operator>)`	Removes every operator contained in {@code toDelete} from this
collection, matching by reference identity (not {@code equals}).
`accept(visitor: org.aspose.pdf.operators.IOperatorSelector)`	Visitor entry point: invokes {@link IOperatorSelector#visit(Operator)}
for each operator in this collection, in order.
`clear()`	Removes every operator from this collection.
`iterator()` → `Iterator<Operator>`	Returns an iterator over the operators.
`getAll()` → `List<Operator>`	Returns an unmodifiable view of all operators.
`toString()` → `String`	Returns a string representation of all operators, one per line.
