Interface FeatureStoreTransforms

All Superinterfaces:
Cloneable, org.gvsig.tools.lang.Cloneable, Iterable<FeatureStoreTransform>
public interface FeatureStoreTransforms extends org.gvsig.tools.lang.Cloneable, Iterable<FeatureStoreTransform>
This interface represents a container for store transforms. Provides access to transforms by index and by iterator, and also allows adding and removing transforms.

  • Method Details

    • getTransform

      FeatureStoreTransform getTransform(int index)
      Returns the FeatureStoreTransform given its index.
      Parameters:
      index - a position in this FeatureStoreTransforms
      Returns:
      the FeatureStoreTransform that is stored in the given index.

    • add

      FeatureStoreTransform add(FeatureStoreTransform transform) throws DataException
      Adds a FeatureStoreTransform to this container.
      Parameters:
      transform - the FeatureStoreTransform to add
      Returns:
      the added FeatureStoreTransform
      Throws:
      DataException

    • size

      int size()
      Returns the number of FeatureStoreTransforms stored in this container
      Returns:
      number of FeatureStoreTransforms stored in this container

    • isEmpty

      boolean isEmpty()
      Indicates whether this container is empty.
      Returns:
      true if this container is empty, false if not

    • iterator

      Iterator<FeatureStoreTransform> iterator()
      Returns an iterator over this container elements.
      Specified by:
      iterator in interface Iterable<FeatureStoreTransform>
      Returns:
      an iterator over this container elements.

    • clear

      void clear()
      Empties this container.

    • remove

      Object remove(int index)
      Removes the FeatureStoreTransform given its index.
      Parameters:
      index - the position of the FeatureStoreTransform to remove.
      Returns:
      the removed object

    • remove

      boolean remove(FeatureStoreTransform transform)
      Removes the given FeatureStoreTransform.
      Parameters:
      transform - FeatureStoreTransform to remove
      Returns:
      true if the transform was successfully removed, false if not.

    • isTransformsOriginalValues

      boolean isTransformsOriginalValues()
      Retruns true if any FeatureStoreTransform make changes of any previous attributes values.
      If all FeatureStoreTransform affects only to attributes defition, the FeatureSet performance can be better.
      Returns:
