Class OptionalContentMembership

java.lang.Object
  org.icepdf.core.pobjects.Dictionary
      org.icepdf.core.pobjects.OptionalContentMembership

All Implemented Interfaces:

OptionalContents

public class OptionalContentMembership
extends Dictionary
implements OptionalContents

As mentioned above, content may belong to a single optional content group and shall be visible when the group is ON and invisible when it is OFF. To express more complex visibility policies, content shall not declare itself to belong directly to an optional content group but rather to an optional content membership dictionary.

Note: currently no support for the visibility expression (VE) array.

Since:

5.0
