maybe use
{code}
public static String getDictionaryHash(COSBase base) throws IOException {
if (base instanceof COSDictionary) {
StringBuilder sb = new StringBuilder();
for (Map.Entry<COSName, COSBase> x : ((COSDictionary)
base).entrySet()) {
sb.append(x.getKey());
sb.append(":");
sb.append(getDictionaryHash(x.getValue()));
sb.append(";");
}
if (base instanceof COSStream) {
InputStream stream = ((COSStream)base).getFilteredStream();
byte[] b = IOUtils.toByteArray(stream);
sb.append("COSStream{").append(Arrays.hashCode(b)).append("}");
}
return sb.toString();
} else if (base instanceof COSObject) {
COSObject obj = (COSObject) base;
return obj.getObjectNumber().intValue() + " " +
obj.getGenerationNumber().intValue();
} else {
return base.toString();
}
}
{code}
