directory

java.io.File directory

Local directory used for caching.

grid2DSquareCellChunks

java.util.HashMap<K,V> grid2DSquareCellChunks

The chunks that make up this instance. HashMap is prefered to an array or an array of arrays due to garbage collection caching advantages. TODO: 1. Would it be better to use a; ReferenceMap, ReferenceIdentityMap, IdentityHashMap, or Hashtable in place of this HashMap? 2. Should this be transient?

gridStatistics

GridStatisticsAbstract gridStatistics

A reference to the grid Statistics Object.

nChunkRows

int nChunkRows

For storing the number of chunk rows.

nChunkCols

int nChunkCols

For storing the number of chunk columns.

chunkNrows

int chunkNrows

For storing the (usual) number of cells in a chunk row. This may be different for chunks in the final row of chunks (final as in row major order)

chunkNcols

int chunkNcols

For storing the (usual) number of cells in a chunk column. This may be different for chunks in the final row of chunks (final as in row major order)

nrows

long nrows

For storing the number of rows in the grid.

ncols

long ncols

For storing the number of columns in the grid.

name

java.lang.String name

For storing the name of the grid.

dimensions

java.math.BigDecimal[] dimensions

For storing cellsize, minx, miny, maxx, maxy Although maxx and maxy could be easily calculated if required, for convenience they are calculated by default during grid construction.

Class uk.ac.leeds.ccg.andyt.grids.core.Grid2DSquareCellAbstract.CellID extends java.lang.Object implements Serializable

Serialized Fields

cellRowIndex

long cellRowIndex

For storing the row in which the cell is positioned

cellColIndex

long cellColIndex

For storing the column in which the cell is positioned

hashCode

int hashCode

For storing a hashCode for the cell. NB. When the number of cells in a grid is more than the maximum int value care should be taken that hashCodes are distributed in a relatively even way. Operations will slow down greatly if a large number of cells have a CellID with the same hashCode.

Serialized Fields

chunkRowIndex

int chunkRowIndex

For storing the chunk row index

For storing the chunk column index

hashCode

int hashCode

For storing a hashCode for this ChunkID. NB. When the number of cells in a chunk is more than the maximum int value care should be taken to distributed hashcodes in a relatively even way. Operations may slow down greatly if a large number of chunks have ChunkIDs with the same hashCode.
