This method checks the inside key-value pairs of CosDictionary and returns true if they have same number of key-value pairs and also equal data for each key. Returns false if passed CosObject is not an instance of CosDictionary. This maintains a continuously growing list of indirect CosObject pairs, which have already been compared, to get rid of infinite recursion.

value -

Returns:

Obtains the object corresponding to the specified key. If the object does not exist, the inheritance chain of this dictionary is walked using the parentKey to find the parent dictionary. Each parent dictionary is subsequently searched until either the key is found, or we run out of parents. An indirect object reference is resolved to the referenced object before being returned.

Parameters:

name - A key in the dictionary

parentKey - The key that specifies the "parent" dictionary

Returns:

Object corresponding to the specified key.

Throws:

PDFCosParseException

PDFIOException

PDFSecurityException
