Constructor Detail

GestureFile

public GestureFile(File f,
                   GesturePackage gp)

GestureFile

public GestureFile(File f)

Method Detail

setGesturePackage

public void setGesturePackage(GesturePackage gp)

getGesturePackage

public GesturePackage getGesturePackage()

setUseAutosave

public void setUseAutosave(boolean useIt)

isUseAutosave

public boolean isUseAutosave()

write

public void write()
           throws IOException

Write the gesturePackage to its file. Overwrites any existing file.

writeAutoSave

public void writeAutoSave()
                   throws IOException

read

public void read()
          throws ClassNotFoundException,
                 InvalidClassException,
                 InvalidObjectException,
                 IOException,
                 FileNotFoundException,
                 ParseException

Read the gesture set from the file. If useAutoSave is true, reads autosave file if it exists and is newer.

Throws:

ClassNotFoundException - indicates a problem with deserialization

InvalidClassException - indicates a problem with deserialization

InvalidObjectException - indicates a problem with deserialization

ParseException - probably a problem with ill-formed numbers
