Method Details

getInputStream

public InputStream getInputStream()
                           throws IOException

Description copied from interface: NativeBinaryLocator

Returns an input stream from which the contents of the binary archive can be read.

Specified by:

getInputStream in interface NativeBinaryLocator

Returns:

An input stream. May return null.

Throws:

IOException - If the archive could not be located or read.

getIdentifier

public String getIdentifier()
                     throws IOException

Description copied from interface: NativeBinaryLocator

Returns a string identifier that represents the archive returned. This identifier should be stable (same value for the same archive), even across multiple JVM invocations. The value must only contain characters that can be used as a legal file name.

The default implementation needs to read the full archive contents and is relatively slow. Implementations of this interface can override this method to provide a faster way to create a stable identifier based on the specific implementation.

The default implementation hashes the archive contents and uses it to return a stable file name.

Specified by:

getIdentifier in interface NativeBinaryLocator

Returns:

A stable indentifier that can be used as a file name.

Throws:

IOException - If the stream could not be read.

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
