  • Method Details

    • setOwner

      public void setOwner(ProductNode owner)
      Called when this node is added to or removed from a product. Overridden in order to create placemarks for features that are still without a placemark counterpart.
      Overrides:
      setOwner in class ProductNode
      Parameters:
      owner - the new owner

    • getPlacemarkDescriptor

      public PlacemarkDescriptor getPlacemarkDescriptor()

    • getPlacemarkGroup

      public PlacemarkGroup getPlacemarkGroup()

    • setModified

      public void setModified(boolean modified)
      Description copied from class: ProductNode
      Sets this node's modified flag.

      If the modified flag changes to true and this node has an owner, the owner's modified flag is also set to true.

      Overrides:
      setModified in class ProductNode
      Parameters:
      modified - whether or not this node is beeing marked as modified.

    • getFeatureType

      public org.opengis.feature.simple.SimpleFeatureType getFeatureType()
      Returns:
      The feature type (= feature source schema).

    • getFeatureCollection

      public org.geotools.feature.DefaultFeatureCollection getFeatureCollection()
      Returns:
      The feature collection.

    • getEnvelope

      public org.geotools.geometry.jts.ReferencedEnvelope getEnvelope()
      Gets the bounding box for the features in this feature collection.
      Returns:
      the envelope of the geometries contained by this feature collection.

    • getRawStorageSize

      public long getRawStorageSize(ProductSubsetDef subsetDef)
      Description copied from class: ProductNode
      Gets an estimated, raw storage size in bytes of this product node.
      Specified by:
      getRawStorageSize in class ProductNode
      Parameters:
      subsetDef - if not null the subset may limit the size returned
      Returns:
      the size in bytes.

    • getDefaultStyleCss

      public String getDefaultStyleCss()

    • setDefaultStyleCss

      public void setDefaultStyleCss(String defaultStyleCss)

    • getStyleCss

      public String getStyleCss()

      public void setStyleCss(String styleCss)

    • acceptVisitor

      public void acceptVisitor(ProductVisitor visitor)
      Description copied from class: ProductNode
      Accepts the given visitor. This method implements the well known 'Visitor' design pattern of the gang-of-four. The visitor pattern allows to define new operations on the product data model without the need to add more code to it. The new operation is implemented by the visitor.
      Specified by:
      acceptVisitor in class ProductNode
      Parameters:
      visitor - the visitor

    • isPermanent

      public boolean isPermanent()
      Internal API. Don't use.
      Returns:
      If true, prevents this node from being removed.

    • setPermanent

      public void setPermanent(boolean permanent)
      Internal API. Don't use.
      Parameters:
      permanent - If true, prevents this node from being removed.

    • isInternalNode

      @Deprecated public boolean isInternalNode()
      Deprecated.
      Since BEAM 4.10. No use.
      Returns:
      true if the feature type's name starts with "org.esa.snap."

    • getDefaultCSS

      @Deprecated public String getDefaultCSS()
      Deprecated.
      since BEAM 4.10, use getDefaultStyleCss()

    • setDefaultCSS

      @Deprecated public void setDefaultCSS(String defaultCSS)
      Deprecated.
      since BEAM 4.10, use setDefaultStyleCss()

    • fireFeaturesAdded

      @Deprecated public void fireFeaturesAdded(org.opengis.feature.simple.SimpleFeature... features)
      Deprecated.
      since 6.0, method is public by accident, should only be used internally
      Informs clients which have registered a ProductNodeListener with the Product containing this VectorDataNode, that one or more OpenGIS SimpleFeatures have been added to the underlying FeatureCollection.

      The method fires a product node property change event, where the propertyName is PROPERTY_NAME_FEATURE_COLLECTION, the oldValue is null, and the newValue is the array of features added.

      Parameters:
      features - The feature(s) added.

    • fireFeaturesRemoved

      @Deprecated public void fireFeaturesRemoved(org.opengis.feature.simple.SimpleFeature... features)
      Deprecated.
      since 6.0, method is public by accident, should only be used internally
      Informs clients which have registered a ProductNodeListener with the Product containing this VectorDataNode, that one or more OpenGIS SimpleFeatures have been removed from the underlying FeatureCollection.

      The method fires a product node property change event, where the propertyName is PROPERTY_NAME_FEATURE_COLLECTION, the oldValue is the array of features removed, and the newValue is null.

      Parameters:
      features - The feature(s) removed.

    • fireFeaturesChanged

      public void fireFeaturesChanged(org.opengis.feature.simple.SimpleFeature... features)
      Deprecated.
      since 6.0, method is public by accident, should only be used internally
      Informs clients which have registered a ProductNodeListener with the Product containing this VectorDataNode, that one or more OpenGIS SimpleFeatures from from the underlying FeatureCollection have been changed.

      The method fires a product node property change event, where the propertyName is PROPERTY_NAME_FEATURE_COLLECTION, and both oldValue and newValue are the same array of features changed.

      Parameters:
      features - The feature(s) changed.
