Constructor Details

ShapeRamCache

public ShapeRamCache(SpatialStore shapefile)

Method Details

getValueAt

public Object getValueAt(int row,
 int column,
 int period)

Implementation of data accessor

Specified by:

getValueAt in class AttributeStore

Parameters:

row - The row containing the cell

column - The column containing the cell

period - The period of interest

Returns:

An object containing the cell value.

getSelection

public BitSet getSelection(Extent2D e)

Return a selection bitmap

Parameters:

e - The selection rectangle of interest

Returns:

A set of selected records

getExtent2D

public Extent2D getExtent2D()

Description copied from class: ShapeStore

Return the extent of the shapefile

Specified by:

getExtent2D in interface SpatialStore

Overrides:

getExtent2D in class ShapeStore

Returns:

A rectangle

getRowCount

public int getRowCount()

Description copied from class: AttributeStore

Get the number of rows in this store

Specified by:

getRowCount in interface SpatialStore

Specified by:

getRowCount in interface TableModel

Specified by:

getRowCount in class AttributeStore

Returns:

the number of rows in this store

getPeriodCount

public int getPeriodCount()

Description copied from class: AttributeStore

Get the total number of periods that this store supports

Specified by:

getPeriodCount in class AttributeStore

Returns:

The number of periods in this store

getYearForPeriod

public int getYearForPeriod(int period)

Description copied from class: AttributeStore

Get the ending year for a given period.

Specified by:

getYearForPeriod in class AttributeStore

Parameters:

period - The period of interest

Returns:

the year for a given period

getShape

public GeoShape getShape(int id,
 int period)

Description copied from interface: SpatialStore

Get the shape object for a individual feature

Parameters:

id - The record of interest

period - The period of interest

Returns:

A shape object

getCoordinates

public double[][] getCoordinates(int id)

Description copied from interface: SpatialStore

Get a list of raw coordinates for the points in this shape.

Parameters:

id - The row of interest

Returns:

An array of arrays of coordinate points. Each element in the outer array contains a 'part' of the underlying shape (for example, and island or a multi-part polygon). The inner array index holds the coordinate points of that part.

getType

public int getType()

Description copied from interface: SpatialStore

Get the type of this table. Types may be one of SpatialStore.POINT, SpatialStore.CURVE, SpatialStore.POLYLINE, SpatialStore.SURFACE, SpatialStore.POLYGON, or SpatialStore.MULTIPOINT.

getExtent2D

public Extent2D getExtent2D(int id,
 int period)

Description copied from interface: SpatialStore

Get the enclosing rectangle of a feature

Parameters:

id - The record of interest

period - The period of interest

Returns:

A rectangle

hasSpatialIndex

public boolean hasSpatialIndex()

Description copied from interface: SpatialStore

Query if this SpatialStore has a spatial index

canBuildSpatialIndex

public boolean canBuildSpatialIndex()

Description copied from interface: SpatialStore

Query if this SpatialStore is capable of building a spatial index

makeSpatialIndex

public void makeSpatialIndex()

Description copied from interface: SpatialStore

Request that this SpatialStore create a spatial index
