Class ZipArchiveOutputStream

java.lang.Object
java.io.OutputStream
java.io.FilterOutputStream
java.util.zip.DeflaterOutputStream
com.codename1.io.zip.ZipArchiveOutputStream
All Implemented Interfaces:
AutoCloseable
public class ZipArchiveOutputStream extends DeflaterOutputStream
Streaming ZIP writer with optional Unix permissions. Works on the JVM and ParparVM. Payloads are never buffered in full. Central-directory metadata is limited to 16 MiB and 65534 entries; ZIP64 is explicitly refused. finish() leaves the destination open; close() closes it even after a failure. Input streams are owned by the caller. This stream is not thread safe.

  • Method Details

    • setMethod

      public void setMethod(int method)

    • setLevel

      public void setLevel(int level)

    • setComment

      public void setComment(String comment)

    • putNextEntry

      public void putNextEntry(ZipEntry entry) throws IOException
      Writes an entry without Unix attributes, like java.util.zip.ZipOutputStream.
      Throws:
      IOException

    • putNextEntry

      public void putNextEntry(ZipEntry entry, int permissions) throws IOException
      Writes an entry with Unix permission bits (for example 0755 or 0644). File/directory type bits are inferred from the trailing slash. Symlinks and special files are not created. Values outside 0000..0777 are refused.
      Throws:
      IOException

    • write

      public void write(int value) throws IOException
      Description copied from class: OutputStream
      Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored. Subclasses of OutputStream must provide an implementation for this method.
      Overrides:
      write in class DeflaterOutputStream
      Throws:
      IOException

    • write

      public void write(byte[] data, int off, int len) throws IOException
      Description copied from class: OutputStream
      Writes len bytes from the specified byte array starting at offset off to this output stream. The general contract for write(b, off, len) is that some of the bytes in the array b are written to the output stream in order; element b[off] is the first byte written and b[off+len-1] is the last byte written by this operation. The write method of OutputStream calls the write method of one argument on each of the bytes to be written out. Subclasses are encouraged to override this method and provide a more efficient implementation. If b is null, a NullPointerException is thrown. If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown.
      Overrides:
      write in class DeflaterOutputStream
      Throws:
      IOException

    • deflate

      protected void deflate() throws IOException
      Overrides:
      deflate in class DeflaterOutputStream
      Throws:
      IOException

    • closeEntry

      public void closeEntry() throws IOException
      Throws:
      IOException

    • finish

      public void finish() throws IOException
      Overrides:
      finish in class DeflaterOutputStream
      Throws:
      IOException

    • flush

      public void flush() throws IOException
      Description copied from class: OutputStream
      Flushes this output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination. The flush method of OutputStream does nothing.
      Overrides:
      flush in class DeflaterOutputStream
      Throws:
      IOException

    • close

      public void close() throws IOException
      Description copied from class: OutputStream
      Closes this output stream and releases any system resources associated with this stream. The general contract of close is that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened. The close method of OutputStream does nothing.
      Specified by:
      close in interface AutoCloseable
      Overrides:
      close in class DeflaterOutputStream
      Throws:
      IOException
