Method Detail

getEntryName

public String getEntryName()

Return the entry name for this connection. This method returns null if the JAR file URL corresponding to this connection points to a JAR file and not a JAR file entry.

Overrides:

getEntryName in class JarURLConnection

Returns:

the entry name for this connection, if any.

getJarFile

public JarFile getJarFile()
                   throws IOException

Return the JAR file for this connection. The returned object is not modifiable, and will throw UnsupportedOperationException if the caller attempts to modify it.

Specified by:

getJarFile in class JarURLConnection

Returns:

the JAR file for this connection. If the connection is a connection to an entry of a JAR file, the JAR file object is returned

Throws:

IOException - if an IOException occurs while trying to connect to the JAR file for this connection.

See Also:

connect()

getManifest

public Manifest getManifest()
                     throws IOException

Returns the Manifest for this connection, or null if none. The returned object is not modifiable, and will throw UnsupportedOperationException if the caller attempts to modify it.

Overrides:

getManifest in class JarURLConnection

Returns:

the manifest object corresponding to the JAR file object for this connection.

Throws:

IOException - if getting the JAR file for this connection causes an IOException to be trown.

See Also:

getJarFile()

getJarEntry

public JarEntry getJarEntry()
                     throws IOException

Return the JAR entry object for this connection, if any. This method returns null if the JAR file URL corresponding to this connection points to a JAR file and not a JAR file entry. The returned object is not modifiable, and will throw UnsupportedOperationException if the caller attempts to modify it.

Overrides:

getJarEntry in class JarURLConnection

Returns:

the JAR entry object for this connection, or null if the JAR URL for this connection points to a JAR file.

Throws:

IOException - if getting the JAR file for this connection causes an IOException to be trown.

See Also:

getJarFile(), getJarEntry()

getAttributes

public Attributes getAttributes()
                         throws IOException

Return the Attributes object for this connection if the URL for it points to a JAR file entry, null otherwise.

Overrides:

getAttributes in class JarURLConnection

Returns:

the Attributes object for this connection if the URL for it points to a JAR file entry, null otherwise.

Throws:

IOException - if getting the JAR entry causes an IOException to be thrown.

See Also:

getJarEntry()

getMainAttributes

public Attributes getMainAttributes()
                             throws IOException

Returns the main Attributes for the JAR file for this connection.

Overrides:

getMainAttributes in class JarURLConnection

Returns:

the main Attributes for the JAR file for this connection.

Throws:

IOException - if getting the manifest causes an IOException to be thrown.

See Also:

getJarFile(), getManifest()

getCertificates

public Certificate[] getCertificates()
                              throws IOException

Return the Certificate object for this connection if the URL for it points to a JAR file entry, null otherwise. This method can only be called once the connection has been completely verified by reading from the input stream until the end of the stream has been reached. Otherwise, this method will return null

Overrides:

getCertificates in class JarURLConnection

Returns:

the Certificate object for this connection if the URL for it points to a JAR file entry, null otherwise.

Throws:

IOException - if getting the JAR entry causes an IOException to be thrown.
