Method Detail

get_Item

public Operator get_Item(int index)

Gets operator by its index.

 Example demonstrates how to get operator of page contents by index.
 
 
 Document doc = new Document("input.pdf");

 Operator first = oc.get_Item(1);
 
 

Specified by:

get_Item in class BaseOperatorCollection

Parameters:

index - Index of operator. Numbering is starts from 1.

Returns:

Operator from requested index

set_Item

public void set_Item(int index,
            Operator value)

Sets operator by its index.

 Example demonstrates how to get operator of page contents by index.
 
 
 Document doc = new Document("input.pdf");
 OperatorCollection oc = doc.getPages().get_Item(1).getContents();
 Operator first = oc.get_Item(1);
 
 

Specified by:

set_Item in class BaseOperatorCollection
