## org.apache.uima.resource
Interface ExternalResourceDescription

All Superinterfaces:
  Cloneable, MetaDataObject, Serializable, XMLizable

    public interface ExternalResourceDescription

extends MetaDataObject

An `ExternalResourceDescription` object describes a resource that is loaded in the `ResourceManager` and may be shared between components. This object has four properties:

- A name, used to identify the resource.
- A textual description of the resource.
- A `ResourceSpecifier` that describes how to create the resource (for simple data resources this will be a `FileResourceSpecifier` that contains a URL to the data file.
- The name of a Java class that implements the specified interface and which also implements `SharedResourceObject`.

Method Summary
`String` | `getDescription()` Retrieves the textual description of the resource.
`String` | `getImplementationName()` Retrieves the name of the Java class to be instantiated from the resource data.
`String` | `getName()` Retrieves the name by which the resource is identified.
`ResourceSpecifier` | `getResourceSpecifier()` Retrieves the `ResourceSpecifier` that describes how to create the resource.
`void` | `setDescription(String aDescription)` Retrieves the textual description of the resource.
`void` | `setImplementationName(String aName)` Sets the name of the Java class to be instantiated from the resource data.
`void` | `setName(String aName)` Sets the name by which the resource is identified.
`void` | `setResourceSpecifier(ResourceSpecifier aSpecifier)` Sets the `ResourceSpecifier` that describes how to create the resource.

Method Detail

### getName

    String getName()

  Retrieves the name by which the resource is identified.

  Returns:
    the name of this resource.

### setName

    void setName(String aName)

  Sets the name by which the resource is identified.

  Parameters:
    `aName` - the name of this resource.

### getDescription

    String getDescription()

  Retrieves the textual description of the resource.

  Returns:
    the textual description of the resource.

### setDescription

    void setDescription(String aDescription)

  Retrieves the textual description of the resource.

  Parameters:
    `aDescription` - the textual description of the resource.

### getResourceSpecifier

    ResourceSpecifier getResourceSpecifier()

  Retrieves the `ResourceSpecifier` that describes how to create the resource.

  Returns:
    the `ResourceSpecifier` for this external resource

### setResourceSpecifier

    void setResourceSpecifier(ResourceSpecifier aSpecifier)

  Sets the `ResourceSpecifier` that describes how to create the resource.

  Parameters:
    `aSpecifier` - the `ResourceSpecifier` for this external resource
  Throws:
    `UIMA_UnsupportedOperationException` - if this object is not modifiable

### getImplementationName

    String getImplementationName()

  Retrieves the name of the Java class to be instantiated from the resource data. This must extend `SharedResourceObject` as well as the interface specified by `ExternalResourceDependency.getInterfaceName()`.

  Returns:
    the name of the Java class implementing the resource access

### setImplementationName

    void setImplementationName(String aName)

  Sets the name of the Java class to be instantiated from the resource data. This must extend `SharedResourceObject` as well as the interface specified by `ExternalResourceDependency.getInterfaceName()`.

  Parameters:
    `aName` - the name of the Java class implementing the resource access
  Throws:
    `UIMA_UnsupportedOperationException` - if this object is not modifiable
