public class ConfigurableDataResource_impl extends Resource_ImplBase implements DataResource
DataResource implementation that can read data from a file via a URL. There is
an attribute for specifying the location of a local cache for a remote file, but this is not
currently being used.PARAM_RELATIVE_PATH_RESOLVERPARAM_AGGREGATE_SOFA_MAPPINGS, PARAM_CONFIG_MANAGER, PARAM_CONFIG_PARAM_SETTINGS, PARAM_EXTERNAL_OVERRIDE_SETTINGS, PARAM_PERFORMANCE_TUNING_SETTINGS, PARAM_RESOURCE_MANAGER, PARAM_UIMA_CONTEXT| Constructor and Description |

(indicating no URL available), this method may still return a URI. This can be the case if the

public boolean equals(Object obj)
DataResourceDataResource is equal to another DataResource.
It is important that DataResource implementations override this method
appropriately, because the ResourceManager can make use of this method to determine
when cached data can be reused. Two DataResources that are equal
according to this method will be considered to provide access to the same data; therefore, a
common cache can be used.equals in interface DataResourceequals in class Objectobj - the object to compare toaObj is a DataResource and provides
access to the same data as this object.DataResource.equals(java.lang.Object)public int hashCode()
DataResourceDataResource. As always, if the
DataResource.equals(Object) method is overridden, this method should also be overridden. Two
objects that are equal must have the same hash code.hashCode in interface DataResourcehashCode in class ObjectDataResource.hashCode()Copyright © 2006–2021 The Apache Software Foundation. All rights reserved.
