Class DelegateFeatureReader<T extends FeatureType,​F extends Feature>

  • All Implemented Interfaces:
    Closeable, AutoCloseable, FeatureReader<T,​F>
    Direct Known Subclasses:
    DelegateSimpleFeatureReader
    public class DelegateFeatureReader<T extends FeatureType,​F extends Feature>
extends Object
implements FeatureReader<T,​F>
    A FeatureReader that wraps up a normal FeatureIterator.

    This class is useful for faking (and testing) the Resource based API against in memory datastructures. You are warned that to complete the illusion that Resource based IO is occuring content will be duplicated.

    • Method Detail

      • getFeatureType

        public T getFeatureType()
        Description copied from interface: FeatureReader
        Return the FeatureType this reader has been configured to create.
        Specified by:
        getFeatureType in interface FeatureReader<T extends FeatureType,​F extends Feature>
        Returns:
        the FeatureType of the Features this FeatureReader will create.

      • hasNext

        public boolean hasNext()
                throws IOException
        Description copied from interface: FeatureReader
        Query whether this FeatureReader has another Feature.
        Specified by:
        hasNext in interface FeatureReader<T extends FeatureType,​F extends Feature>
        Returns:
        True if there are more Features to be read. In other words, true if calls to next would return a feature rather than throwing an exception.
        Throws:
        IOException - If an error occurs determining if there are more Features.

      • close

        public void close()
           throws IOException
        Description copied from interface: FeatureReader
        Release the underlying resources associated with this stream.

        Specified by:
        close in interface Closeable
        Specified by:
        close in interface FeatureReader<T extends FeatureType,​F extends Feature>
        Throws:
        IOException - if an I/O error occurs
