    • KEY_UUID唯一标识符

       

      public static final java.lang.String KEY_UUID

      The key corresponding to the UUID of the ADF, used as a unique identifier for the ADF file. Returned as a null terminated character array.

      See Also:

      Constant Field Values

    • KEY_NAME唯一标识名称

       

      public static final java.lang.String KEY_NAME

      The key corresponding to the human readable name of the ADF file. Returned as a null terminated character array.

      See Also:

      Constant Field Values

    • KEY_TRANSFORMATION

       

      public static final java.lang.String KEY_TRANSFORMATION

      The key corresponding to a transform from the ADF to a global coordinate frame. The data consists of 7 double precision elements:与从ADF转到全球坐标框架相关的键。该数据包括7个双精度类型的元素：

      • x, y, z :ECEF (earth centered earth fixed) Cartesian frame of reference at the center of the earth which rotates with the earth).
      • qx, qy, qz, qw : Hamilton Quaternion.

      The default corresponding values are:
      (x, y, z, qx, qy, qz, qw) = (0, 0, 0, 0, 0, 0, 1).

      See Also:

      Constant Field Values

    • KEY_DATE_MS_SINCE_EPOCH

       

      public static final java.lang.String KEY_DATE_MS_SINCE_EPOCH

      The key corresponding to the creation date of the ADF measured in milliseconds since Unix epoch as a 64-Bit unsigned integer. Setting this value on the client side using TangoAreaDescriptionMetadata_set()will have no effect on the data stored by the server. Also, when you call TangoService_saveAreaDescriptionMetadata() it ignores the value.

      See Also:

      Constant Field Values

    • CREATOR

       

      public static final <any> CREATOR

      Implements the required Creator interface for an Android Parcelable. This allows reading and writing to an Android Parcel object.

    • get获取

       

      public byte[] get(java.lang.String key)

      Searches through the metadata list for a key that matches the parameter key. If such a key is found, returns the value associated with that key.搜寻与key相符的子数据列表。如果该key发现，将返回与key相关的值。

      Parameters:

      key - The string key value of the parameter to get.

      Returns:

      The value of the parameter in bytes.

    • set设置

       

      public void set(java.lang.String key,
                      byte[] value)

      Sets the value associated with an area description key to a new value.设置与一个区域描述key相关的值。

      Parameters:

      key - The string key value of the parameter to set.

      value - The value to set the key to in bytes.

    • keySet键集合

       

      public java.util.Set<java.lang.String> keySet()

      Gets the set of keys.获取键的集合。

    • describeContents描述内容

       

      public int describeContents()

      Needed to implement the Android Parcelable interface. Can be used to describe the kinds of objects contained in Parcelable's marshalled representation, but we'll just return 0 since we don't need that ability.要实现Android Parcelable接口必须实现该方法。可以被用来描述包含在Parcelable集合表示中的对象的种类，但是我们返回0因为我们不需要那个功能。

      Returns:

      Will always return 0.

    • readFromParcel

       

      public void readFromParcel(Parcel in)

      Populates a TangoAreaDescriptionMeta object with data from an Android Parcel.用Android Parcel中的数据填充TangoAreaDescriptionMeta对象。

      Parameters:

      in - The Parcel to read from.

    • writeToParcel

       

      public void writeToParcel(Parcel dest,
                                int flags)

      Writes a TangoAreaDescriptionMeta object to an Android Parcel.将TangoAreaDescriptionMeta对象写入Android Parcel中。

      Parameters:

      dest - The Parcel to write to.

      flags - This parameter is required by the Parcelable interface, but is unused for this implementation.
