Interface IDissolveRule

All Known Implementing Classes:

AdjacencyDissolveRule, DissolveRule

public interface IDissolveRule

Forces to IDissolveCriteria to fetch geometries from ReadableVectorial (for performance reasons, once a criteria has verified a spatial conditions, it caches IGeometry, to avoid reading them many times)

Method Summary

Modifier and Type	Method and Description
java.lang.String	getFieldName() Gets the index of the field to apply the dissolve rule
java.lang.String	getFieldName(java.lang.String func) Returns the name of the field for the selected function
boolean	isFunctionIncluded(java.lang.String func) Returns true if the selected function is included in the summary
boolean	verifyIfDissolve(Geometry g1, Geometry g2, Feature f1, Feature f2) Verifies if the given geometries will be dissolved
