Performing a Search

In this sample, we:

use an existing MediaCollection to select a MediaObject to use as a source for the search

perform the search

retrieve and display the resulting images.

// create a MediaCollection object to hold the MediaCollection on disk

MediaCollection mediaCollection = (MediaCollection) Eve.newMediaCollection();

try

{

// open the collection and get the keys

mediaCollection.open ("\\temp\\myCollection");

long results[] = mediaCollection.getKeys();

// make a MediaObject to hold the query image

MediaObject mediaObject = (MediaObject) Eve.newMediaObject();

mediaObject = mediaCollection.getMediaObject (results[0]);

// make a SearchParameters object

SearchParameters searchParameters = (SearchParameters) Eve.newSearchParameters();

// set the parameters to do a 50-50 shape and texture search

searchParameters.setSearch(Eve.SHAPE, true, 0.5);

searchParameters.setSearch(Eve.TEXTURE, true, 0.5);

// make a SearchResults object

SearchResults searchResults[] = mediaCollection.search

(mediaObject, searchParameters);

// iterate through the results and output the filenames

for (i = 0; i < searchResults.length; i++)

{

MediaObject temp = mediaCollection.getMediaObject

(searchResults[i].getKey());

String filename = (String) temp.getProperty("originalFile");

System.out.println(

"Target: " + i + " File: " + filename + " : " + searchResults[i]);

// if everything checks out, raise the flag

if (mediaObject.getKey() == searchResults[i].getKey())

flag = true;

}

// close the collection

mediaCollection.close();

// report our final status

if (flag)

System.out.println("EDFSearchTest: OK");

else

System.out.println("EDFSearchTest: Error: Find Failed");

}

catch (Exception e)

{

System.out.println("Error: " + e);

e.printStackTrace();

System.out.println("EDFSearchTest: Error");

try

{

// always try to close the collection

mediaCollection.close();

}

catch (Exception ignore)

{

}

}
