com.luciad.format.s57.TLcdS57Preprocessor

public class TLcdS57Preprocessor
extends Object

S-57 preprocessor that precomputes some S-57 object properties which are used by the S-52 symbology, but which are too expensive to compute real-time in the painting thread.

These properties are computed based on the object class, attributes and geometry of the S-57 objects. Their value may depend not only on their own S-57 object, but also on other S-57 objects with which they spatially interact (touch or overlap).

The results are stored as properties on the domain objects.

The following set of S-57 object properties is precomputed by this preprocessor:

• TLcdS57Point:
  • onFloatingPlatform
  • otherLightsAtSameLocation
  • anyNoSectorLightsAtSameLocation
  • largerOverlappingLightSectorsAtSameLocation
  • minimumDepth
  • maximumDepth
• TLcdS57Line:
  • minimumAdjacentDepth
  • minimumDepth
  • maximumDepth
• TLcdS57Area:
  • minimumDepth
  • maximumDepth
• TLcdS57Edge:
  • minimumAdjacentDepth
  • maximumAdjacentDepth
  • valueOfDepthContour
  • sharedBySlcons
  • sharedByGroup1LndareOrUnsareObject

The TLcdS57ModelDecoder automatically applies preprocessing as a part of the decoding process. The TLcdS57Preprocessor should only be used when S-57 models are created from other code than the TLcdS57ModelDecoder.

Method Detail

preprocess

public void preprocess(ILcd2DBoundsIndexedModel aModel)

Fills out extra properties for the elements of the given model, by looking for other related elements in the model.

Parameters:

aModel - the S-57 model to be preprocessed. The model should contain only S-57 domain objects.
