getDelegate
public SimpleFeatureIterator getDelegate()
-
hasNext
public boolean hasNext()
Description copied from interface:FeatureIterator
Does another Feature exist in this Iteration.Iterator defin: Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)
- Specified by:
hasNext
in interfaceFeatureIterator<SimpleFeature>
- Returns:
- true if more Features exist, false otherwise.
-
next
public SimpleFeature next()
Description copied from interface:FeatureIterator
Get the next Feature in this iteration.- Specified by:
next
in interfaceFeatureIterator<SimpleFeature>
- Returns:
- The next Feature
-
typeAttributes
protected AttributeDescriptor[] typeAttributes(SimpleFeatureType original, SimpleFeatureType target)
Supplies mapping from origional to target FeatureType.Will also ensure that origional can cover target
- Parameters:
target
- Desired FeatureTypeoriginal
- Origional FeatureType- Returns:
- Mapping from originoal to target FeatureType
- Throws:
IllegalArgumentException
- if unable to provide a mapping
-
