public VPFLayerGraphicWarehouse()

Method Detail

setProperties

public void setProperties(java.lang.String prefix,
                          java.util.Properties props)

Set properties of the warehouse.

Overrides:

setProperties in class LayerGraphicWarehouseSupport

Parameters:

prefix - the prefix to use for looking up properties.

props - the properties file to look at.

getFeatures

public java.util.List<java.lang.String> getFeatures()

Get a List of Strings listing all the feature types wanted. Returned with the area features first, then text features, then line features, then point features.

getSkipArray

protected int[] getSkipArray(java.lang.String featureString,
                             DcwRecordFile table,
                             java.lang.String colAppend)

Build an array that lists the columns we require the record to have.

Parameters:

featureString - the (space-separated) list of required columns

table - the table we use to find the column numbers

colAppend - the (possibly null) string we append to the entries in featureString to build the real column name

resetForCAT

public void resetForCAT()

Lets the warehouse know that a different CoverageAttributeTable will be using it. The skip arrays need to be reset.

Specified by:

resetForCAT in interface VPFWarehouse

Overrides:

resetForCAT in class LayerGraphicWarehouseSupport

createFeature

protected boolean createFeature(java.util.List<java.lang.Object> prim,
                                int[] skipArray)

Determine if this primitive should be drawn or skipped.

Parameters:

prim - the list for the primitive feature object.

skipArray - a list of columns.

Returns:

true if any of the columns listed in skipArray is non-null.
