Class GridBasedAlgorithm

  • All Implemented Interfaces:
    com.google.maps.android.clustering.algo.Algorithm 
    
public class GridBasedAlgorithm<T extends ClusterItem>
extends AbstractAlgorithm<T>

    Groups markers into a grid for clustering. This algorithm organizes items into a two-dimensional grid, facilitating the formation of clusters based on proximity within each grid cell. The grid size determines the spatial granularity of clustering, and clusters are created by aggregating items within the same grid cell.

    The effectiveness of clustering is influenced by the specified grid size, which determines the spatial resolution of the grid. Smaller grid sizes result in more localized clusters, whereas larger grid sizes lead to broader clusters covering larger areas.

    • Method Detail

      • addItem

         Boolean addItem(T item)

        Adds an item to the algorithm

        Parameters:
        item - the item to be added
        Returns:

        true if the algorithm contents changed as a result of the call

      • addItems

         Boolean addItems(Collection<T> items)

        Adds a collection of items to the algorithm

        Parameters:
        items - the items to be added
        Returns:

        true if the algorithm contents changed as a result of the call

      • removeItem

         Boolean removeItem(T item)

        Removes an item from the algorithm

        Parameters:
        item - the item to be removed
        Returns:

        true if this algorithm contained the specified element (or equivalently, if this algorithm changed as a result of the call).

      • removeItems

         Boolean removeItems(Collection<T> items)

        Removes a collection of items from the algorithm

        Parameters:
        items - the items to be removed
        Returns:

        true if this algorithm contents changed as a result of the call

      • updateItem

         Boolean updateItem(T item)

        Updates the provided item in the algorithm

        Parameters:
        item - the item to be updated
        Returns:

        true if the item existed in the algorithm and was updated, or false if the item did not exist in the algorithm and the algorithm contents remain unchanged.
