Constructor Detail

COSArrayList

public COSArrayList()

Default constructor.

COSArrayList

public COSArrayList(List<E> actualList,
            COSArray cosArray)

Constructor.

Parameters:

actualList - The list of standard java objects

cosArray - The COS array object to sync to.

COSArrayList

public COSArrayList(E actualObject,
            COSBase item,
            COSDictionary dictionary,
            COSName dictionaryKey)

This is a really special constructor. Sometimes the PDF spec says that a dictionary entry can either be a single item or an array of those items. But in the PDModel interface we really just want to always return a java.util.List. In the case were we get the list and never modify it we don't want to convert to COSArray and put one element, unless we append to the list. So here we are going to create this object with a single item instead of a list, but allow more items to be added and then converted to an array.

Parameters:

actualObject - The PDModel object.

item - The COS Model object.

dictionary - The dictionary that holds the item, and will hold the array if an item is added.

dictionaryKey - The key into the dictionary to set the item.

COSArrayList

public COSArrayList(E actualObject,
            COSBase item,
            COSDictionary dictionary,
            String dictionaryKey)

Deprecated. use the COSArrayList(Object, COSBase, COSDictionary, COSName) method instead
