JdkZipExporterDelegate(Archive<?> archive)
Creates a new exporter delegate for exporting archives as ZIP

Method Summary

protected void	closeEntry(ZipOutputStream outputStream) Closes the current entry context for the specified OutputStream

Constructor Detail

JdkZipExporterDelegate

public JdkZipExporterDelegate(Archive<?> archive)
                       throws IllegalArgumentException

Creates a new exporter delegate for exporting archives as ZIP

Throws:

IllegalArgumentException - If the archive has no Assets; JDK ZIP handling cannot support writing out to a ZipOutputStream with no ZipEntrys.

Method Detail

closeEntry

protected final void closeEntry(ZipOutputStream outputStream)
                         throws IOException

Closes the current entry context for the specified OutputStream

Specified by:

closeEntry in class StreamExporterDelegateBase<ZipOutputStream>

Throws:

IOException

See Also:

StreamExporterDelegateBase.closeEntry(java.io.OutputStream)

createOutputStream

protected final ZipOutputStream createOutputStream(OutputStream out)
                                            throws IOException

Creates the real OutputStream to which we'll write, wrapping the provided target.

Specified by:

createOutputStream in class StreamExporterDelegateBase<ZipOutputStream>

Returns:

Throws:

IOException - If an error occurred in creating the stream

See Also:

StreamExporterDelegateBase.createOutputStream(java.io.OutputStream)

putNextExtry

protected final void putNextExtry(ZipOutputStream outputStream,
                                  String context)
                           throws IOException

Writes the next entry (demarcates a new file/folder is to be written)

Specified by:

putNextExtry in class StreamExporterDelegateBase<ZipOutputStream>

Throws:

IOException - If an error occurred writing the entry

See Also:

StreamExporterDelegateBase.putNextExtry(java.io.OutputStream, java.lang.String)

getExportTask

protected Callable<Void> getExportTask(Callable<Void> wrappedTask)

Returns the task used to run the export operation in another Thread. Exposed such that the specified task (which handles the export) may be wrapped in some error handling logic specific to the export process.

Specified by:

getExportTask in class StreamExporterDelegateBase<ZipOutputStream>

Parameters:

wrappedTask - The export task to be wrapped in more specific handling logic
