Field Summary
`static java.lang.String` | `OLE10_NATIVE`

Constructor Summary
`Ole10Native(byte[] data, int offset)` Creates an instance and fills the fields based on the data in the given buffer.
`Ole10Native(byte[] data, int offset, boolean plain)` Creates an instance and fills the fields based on the data in the given buffer.

Method Summary
`static Ole10Native` | `createFromEmbeddedOleObject(POIFSFileSystem poifs)` Creates an instance of this class from an embedded OLE Object.
`java.lang.String` | `getCommand()` Returns the command field - usually the name of the file being embedded including the full path, may be a command specified during embedding the file.
`byte[]` | `getDataBuffer()` Returns the buffer containing the embedded file's data, or `null` if no data was embedded.
`int` | `getDataSize()` Returns the size of the embedded file.
`java.lang.String` | `getFileName()` Returns the fileName field - usually the name of the file being embedded including the full path.
`short` | `getFlags1()` Returns flags1 - currently unknown - usually 0x0002.
`short` | `getFlags2()` Returns flags2 - currently unknown - mostly 0x0000.
`short` | `getFlags3()` Returns the flags3 - currently unknown.
`java.lang.String` | `getLabel()` Returns the label field - usually the name of the file (without directory) but probably may be any name specified during packaging/embedding the data.
`int` | `getTotalSize()` Returns the value of the totalSize field - the total length of the structure is totalSize + 4 (value of this field + size of this field).
`byte[]` | `getUnknown1()` Returns unknown1 field - currently unknown.
`byte[]` | `getUnknown2()` Returns the unknown2 field - currently being a byte[3] - mostly {0, 0, 0}.

Constructor Detail

### Ole10Native

    public Ole10Native(byte[] data,
                       int offset)
                throws Ole10NativeException

  Creates an instance and fills the fields based on the data in the given buffer.

  Parameters:
    `data` - The buffer containing the Ole10Native record
    `offset` - The start offset of the record in the buffer
  Throws:
    `Ole10NativeException` - on invalid or unexcepted data format

### Ole10Native

    public Ole10Native(byte[] data,
                       int offset,
                       boolean plain)
                throws Ole10NativeException

  Creates an instance and fills the fields based on the data in the given buffer.

  Parameters:
    `data` - The buffer containing the Ole10Native record
    `offset` - The start offset of the record in the buffer
    `plain` - Specified 'plain' format without filename
  Throws:
    `Ole10NativeException` - on invalid or unexcepted data format

Method Detail

### createFromEmbeddedOleObject

    public static Ole10Native createFromEmbeddedOleObject(POIFSFileSystem poifs)
                                                   throws java.io.IOException,
                                                          Ole10NativeException

  Creates an instance of this class from an embedded OLE Object. The OLE Object is expected to include a stream "{01}Ole10Native" which contains the actual data relevant for this class.

  Parameters:
    `poifs` - POI Filesystem object
  Returns:
    Returns an instance of this class
  Throws:
    `java.io.IOException` - on IO error
    `Ole10NativeException` - on invalid or unexcepted data format

### getTotalSize

    public int getTotalSize()

  Returns the value of the totalSize field - the total length of the structure is totalSize + 4 (value of this field + size of this field).

  Returns:
    the totalSize

### getFlags1

    public short getFlags1()

  Returns flags1 - currently unknown - usually 0x0002.

  Returns:
    the flags1

### getLabel

    public java.lang.String getLabel()

  Returns the label field - usually the name of the file (without directory) but probably may be any name specified during packaging/embedding the data.

  Returns:
    the label

### getFileName

    public java.lang.String getFileName()

  Returns the fileName field - usually the name of the file being embedded including the full path.

  Returns:
    the fileName

### getFlags2

    public short getFlags2()

  Returns flags2 - currently unknown - mostly 0x0000.

  Returns:
    the flags2

### getUnknown1

    public byte[] getUnknown1()

  Returns unknown1 field - currently unknown.

  Returns:
    the unknown1

### getUnknown2

    public byte[] getUnknown2()

  Returns the unknown2 field - currently being a byte[3] - mostly {0, 0, 0}.

  Returns:
    the unknown2

### getCommand

    public java.lang.String getCommand()

  Returns the command field - usually the name of the file being embedded including the full path, may be a command specified during embedding the file.

  Returns:
    the command

### getDataSize

    public int getDataSize()

  Returns the size of the embedded file. If the size is 0 (zero), no data has been embedded. To be sure, that no data has been embedded, check whether `getDataBuffer()` returns `null`.

  Returns:
    the dataSize

### getDataBuffer

    public byte[] getDataBuffer()

  Returns the buffer containing the embedded file's data, or `null` if no data was embedded. Note that an embedding may provide information about the data, but the actual data is not included. (So label, filename etc. are available, but this method returns `null`.)

  Returns:
    the dataBuffer

### getFlags3

    public short getFlags3()

  Returns the flags3 - currently unknown.

  Returns:
    the flags3
