---------------------------------------
public List<XMPSchema> getSchemasByNamespaceURI(String namespaceURI)
throws IOException
{
List<XMPSchema> result = new LinkedList<XMPSchema>();
Class<?> schemaClass = nsMappings.get(namespaceURI);
if (schemaClass == null)
{
return result;
}
List<XMPSchema> l = getSchemas();
Iterator<XMPSchema> i = l.iterator();
while (i.hasNext())
{
XMPSchema schema = i.next();
if (schemaClass.isAssignableFrom(schema.getClass()))
{
result.add(schema);
}
}
return result;

> Project: PDFBox
> Issue Type: Improvement
> Components: JempBox
> Affects Versions: 1.5.0
> Reporter: Philip Helger
> Priority: Minor
>
> The implementation of getSchemasByNamespaceURI is inefficient, if no
> namespace mapping is present.
> You may consider to call "List<XMPSchema> l = getSchemas();" just before the
> iterator is retrieved.
