Method Summary

OMGraphic	drawFeature(VPFFeatureWarehouse warehouse, double dpplat, double dpplon, LatLonPoint ll1, LatLonPoint ll2, java.util.List<java.lang.Object> text, java.lang.String featureType, int primID) Use the warehouse to create a graphic from a feature in the TextTable.
void	drawTile(VPFGraphicWarehouse warehouse, double dpplat, double dpplon, LatLonPoint ll1, LatLonPoint ll2) Parse the text records for this tile, calling warehouse.createText once for each record in the selection region.

Constructor Detail

TextTable

public TextTable(CoverageTable cov,
                 TileDirectory tile)
          throws FormatException

Construct a TextTable for reading VPF text features.

Parameters:

cov - the CoverageTable for the tile

tile - the tile to parse

Throws:

FormatException - if something goes wrong reading the text

Method Detail

getCoordinates

public CoordFloatString getCoordinates(java.util.List<java.lang.Object> textprim)

Returns the coordinate string for the text primitive

Parameters:

textprim - the text primitive

drawTile

public void drawTile(VPFGraphicWarehouse warehouse,
                     double dpplat,
                     double dpplon,
                     LatLonPoint ll1,
                     LatLonPoint ll2)

Parse the text records for this tile, calling warehouse.createText once for each record in the selection region.

Specified by:

drawTile in class PrimitiveTable

Parameters:

warehouse - the warehouse used for createText calls (must not be null)

dpplat - threshold for latitude thinning (passed to warehouse)

dpplon - threshold for longitude thinngin (passed to warehouse)

ll1 - upperleft of selection region (passed to warehouse)

ll2 - lowerright of selection region (passed to warehouse)

                             int primID)

Use the warehouse to create a graphic from a feature in the TextTable.

Specified by:

drawFeature in class PrimitiveTable

Parameters:

warehouse - the warehouse used for createText calls (must not be null)

dpplat - threshold for latitude thinning (passed to warehouse)

dpplon - threshold for longitude thinngin (passed to warehouse)

ll1 - upperleft of selection region (passed to warehouse)

ll2 - lowerright of selection region (passed to warehouse)

text - a list with the TextTable row contents.

featureType - the string representing the feature type, in case the warehouse wants to do some intelligent rendering.

primID - the primitive ID of the feature, in order to gather attributes if necessary.
