true if the document satisfies the profile.
This calls satisfiesThisProfile(), which does the actual work.raf - The RandomAccessFile being parsedparser - The Parser being used on the filepublic abstract boolean satisfiesThisProfile()
true if the document satisfies the
profile. Subclasses should override satisfiesThisProfile(),
not satisfiesProfile(), as
satisfiesProfile() does some
additional bookkeeping for all subclases.public java.lang.String getText()
protected boolean hasFilters(PdfObject filter, java.lang.String[] names)
true if a Filter object contains a filter name which
matches any of the Strings in the second argument.
Will return false
filter - A PdfObject which may be either a PdfSimpleObject
encapsulating a Name, or a PdfArray of such objects.
If a null value is passed, it doesn't match any filter,
so false is returned.names - An array of Strings naming the filters which should
precipitate a true resultprotected boolean xObjectsOK(PdfDictionary xos)
protected boolean xObjectOK(PdfDictionary xo)
true.
Override to implement tests.
