Constructor Details

WritableStore

public WritableStore(StoreProvider provider,
 StorageConnector connector)
              throws DataStoreException

Creates a new GPX store from the given file, URL or stream object. This constructor invokes StorageConnector.closeAllExcept(Object), keeping open only the needed resource.

Parameters:

provider - the provider of this data store, or null if unspecified.

connector - information about the storage (URL, stream, etc).

Throws:

DataStoreException - if an error occurred while opening the GPX file.

Method Details

updateType

public void updateType(DefaultFeatureType newType)
                throws DataStoreException

Verifies the type of feature instances in this feature set. This method does nothing if the specified type is equal to Store.getType(), or throws IllegalFeatureTypeException otherwise.

Specified by:

updateType in interface WritableFeatureSet

Parameters:

newType - new feature type definition (not null).

Throws:

DataStoreException - if the given type is not compatible with the types supported by the store.

add

public void add(Iterator<? extends AbstractFeature> features)
         throws DataStoreException

Appends new feature instances in this FeatureSet. Any feature already present in this

invalid reference

FeatureSet

will remain unmodified.

Specified by:

add in interface WritableFeatureSet

Parameters:

features - feature instances to append in this FeatureSet.

Throws:

DataStoreException - if the feature stream cannot be obtained or updated.

removeIf

public boolean removeIf(Predicate<? super AbstractFeature> filter)
                 throws DataStoreException

Removes all feature instances from this FeatureSet which matches the given predicate.

Specified by:

removeIf in interface WritableFeatureSet

Parameters:

filter - a predicate which returns true for feature instances to be removed.

Returns:

true if any elements were removed.

Throws:

DataStoreException - if the feature stream cannot be obtained or updated.

replaceIf

public void replaceIf(Predicate<? super AbstractFeature> filter,
 UnaryOperator<AbstractFeature> replacement)
               throws DataStoreException

Updates all feature instances from this FeatureSet which match the given predicate. If the given operator returns null, then the filtered feature is removed.

Specified by:

replaceIf in interface WritableFeatureSet

Parameters:

filter - a predicate which returns true for feature instances to be updated.

replacement - operation called for each matching Feature instance. May return null.

Throws:

DataStoreException - if the feature stream cannot be obtained or updated.

updater

private Updater updater()
                 throws DataStoreException

Returns the helper object to use for updating the GPX file.

Throws:

DataStoreException

write

@Deprecated
public void write(org.opengis.metadata.Metadata metadata,
 Stream<? extends AbstractFeature> features)
           throws DataStoreException

Deprecated.

To be replaced by add(Iterator), after we resolved how to specify metadata.

Replaces the content of this GPX file by the given metadata and features.

Parameters:

metadata - the metadata to write, or null if none.

features - the features to write, or null if none.

Throws:

ConcurrentReadException - if the features stream was provided by this data store.

DataStoreException - if an error occurred while writing the data.
