Method Detail

drawEdgeFeatures

boolean drawEdgeFeatures()

Return true if we may draw some edge features.

drawTextFeatures

boolean drawTextFeatures()

Return true if we may draw some text features.

drawAreaFeatures

boolean drawAreaFeatures()

Return true if we may draw some area features.

resetForCAT

void resetForCAT()

To let the warehouse know that a new CoverageAttributeTable will be using the warehouse. Some warehouses need to reset some tables for this situation.

getGUI

java.awt.Component getGUI(LibrarySelectionTable lst)

Get the GUI to control different aspects of the warehouse.

Parameters:

lst - LibrarySelectionTable to use to get information about the data, if needed.

drawEPointFeatures

boolean drawEPointFeatures()

Return true if we may draw some entity node(point) features.

drawCPointFeatures

boolean drawCPointFeatures()

Return true if we may draw some connected node(point) features.

getFeatures

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.

getUseLibraries

java.util.List<java.lang.String> getUseLibraries()

Get a library name to limit selections from. Used by the LibrarySelectionTable to find out if selection from database should be limitied to tiles or feature from certain libraries. Specified here instead of the LibrarySelectionTable in case the LST is shared among layers, since the warehouse is specific to a particular layer.

setUseLibraries

void setUseLibraries(java.util.List<java.lang.String> lib)

Set a library name to limit selections from. Used by the LibrarySelectionTable to find out if selection from database should be limitied to tiles or feature from certain libraries. Specified here instead of the LibrarySelectionTable in case the LST is shared among layers, since the warehouse is specific to a particular layer. If null the warehouse should use all libraries available to it to gather features.

checkLibraryForUsage

boolean checkLibraryForUsage(java.lang.String libName)

Utility method to check if the specified library name has been set by the configuration as one to use.

Parameters:

libName - the library name to test

Returns:

true if the useLibrary list has not been set, is empty, or if the provided name matches an entry on it.
