  - init
```
public void init()
```
    Initialize and reset this loader manager.
  - getTag
```
public boolean getTag(int aBit)
```
    Check whether geometry tag is set. For possible tags see jv.loader.PgLoaderIf.
    
    See Also:

  - setTag
```
public void setTag(int aBit,
          boolean flag)

    See Also:
    getTag(int)
  - isEnabledOptimization
```
public boolean isEnabledOptimization()
```
    Determines if the loader is allowed to do some optimization on an imported geometry, or if it shall provide the data as found in the geometry file.
    For example, some file formats do not store a connected mesh but provide individual vertices for each face. In this case, a loader manager may identify equal vertices.
    By default this loader manager is enabled to do optimization if the individual loader allows optimization too.
    
    Returns:
    true if loader manager is enabled for optimization.
    Since:
    
    JavaView 2.99.018
  - setEnabledOptimization
```
public void setEnabledOptimization(boolean flag)
```
    Set flag if the loader is allowed to do some optimization on an imported geometry, or if it shall provide the data as found in the geometry file.
    For example, some file formats do not store a connected mesh but provide individual vertices for each face. In this case, a loader manager may identify equal vertices.
    Optimization is sometimes not suitable without further knowledge about a specific data set. Then the loader may be advised to keep the original data by enabling this flag.
    Method must be called before the loader manager starts reading a file.
    
    Parameters:
    flag - true if loader manager is enabled for optimization.
    Since:
    
    JavaView 2.99.018

```
public void setAnimated(boolean flag)
```
    Set flag whether currently loaded data should be interpreted as an animation. This flag is used by specific loaders only whose file format allow such kind of specifications, for example, Maple and Mathematica.

```
public boolean saveImage(java.awt.Image image,
                java.lang.String fileName)
```
    Write an image to a named file whose extension determines the file format.
    
    Parameters:
    image - Image to be saved to file
    fileName - Full file name including path
    
    Returns:
    true on success

  - parseEndOfLine
```
public static boolean parseEndOfLine(java.io.StreamTokenizer st)
                              throws java.io.IOException
```
    Ignore all tokens of a stream until the next end-of-line is reached. The next token will start at the beginning of the new line. This method is useful to skip the rest of a current line. Note, EOL must be significant in the current stream tokenizer.
    
    Returns:
    true if EOL is found, else false, i.e. EOF is found.
    
    Throws:
    
    java.io.IOException
  - parseDouble
```
public static double parseDouble(java.io.StreamTokenizer st)
                          throws java.io.IOException
```
    Deprecated. since JavaView 3.97.040, use jv.number.PuDouble#parseDouble(String) instead.
    
    Parse double value in exponential notation. This method tries to catch different settings of character in the StreamTokenizer, but not any situations might be handled correctly.
    This method first acquires the next token from StreamTokenizer, then analyzes the following token if there is a number in exponential form. If yes, then the number is created in this method, otherwise the second token is pushed back.
    The need for this method arise from the special setup of some StreamTokenizers in JavaView where several characters like 'e', 'E', '+', are sometimes marked as word characters.
    
    Throws:
    
    java.io.IOException
  - parseDouble
```
public static double parseDouble(java.lang.String string)
```
    Deprecated. since JavaView 3.97.040, use jv.number.PuDouble#parseDouble(String) instead.
    
    Parse double value in exponential notation using Double(String).doubleValue(). This method is a convenience to avoid catching NumberFormatException.
  - readAll
```
public static boolean readAll(java.awt.List list,
              java.lang.String fileName)

```
public static boolean readDirs(java.awt.List list,

    Read list of directories from a given XML listing file.
  - readDirs
```
public static java.lang.String[] readDirs(java.lang.String fileName)
```
    Read list of directories from a given XML listing file into array.
  - readAnimation
```
public PgGeometry[] readAnimation(PgJvxSrc[] geomAnim,
                         boolean bShowAnimationPanel)
```
    Create a set of keyframe objects containing a single keyframe from an array of geometries. Method just calls readAnimation(PgJvxSrc [][] geomAnim, ...).
    
    Since:
    
    JavaView 2.46
  - read
```
public static PgGeometry[] read(PgJvxSrc[] geomAnim,

    Deprecated. use non-static method readAnimation() with same method signature.
    
    Create a set of keyframe objects containing a single keyframe from an array of geometries. Method just calls read(PgJvxSrc [][] geomAnim, ...).

                         int lastKey,

                         int lastKey,
                         java.lang.String fileName,
                         int fixedLen)
```
    Create a set of keyframe objects from a set of files. All files must have the same number of geometries. In case the geometries may be of different type within a keyframe, then the i-th geometry in a keyframe must be of the same type for all keyframes.
    An application calling this method typically adds the dynamic geometries of each keyframe to a display or performs another action.
    The argument fixedLen==0 indicates that no leading zeros appear in the keyframe index. A positive value indicates that the keyframe index of the file name must have the format "name.0017.ext" (here fixedLen==4).
    
    Returns:
    an array of keyframe geometries
  - readAnimation
```
public PgGeometry[] readAnimation(PgJvxSrc[][] geomAnim,
                         boolean bShowAnimationPanel)
```
    Create a set of keyframe objects from a double array of geometries and returns the list of dynamic geometries.
    Each keyframe object has a dynamic geometry which represents the current state of a keyframe animation at a specific time.
    The parent of the dynamic geometry is the corresponding keyframe object.
    
    Since:
    
    JavaView 2.46
  - read
```
public static PgGeometry[] read(PgJvxSrc[][] geomAnim,
                boolean bShowAnimationPanel)
```
    Deprecated. use non-static method readAnimation() with same method signature.
    
    Create a set of keyframe objects from a double array of geometries.
