getParameterValue

public static String getParameterValue(String parameter,
                                       Map<String,String> parameters,
                                       Map<String,String> defaultParameters)

Returns a string parameter value. given is a parameter name and two maps with name/value parameters. If the parameter is not available in the first set, the default value is returned.

Parameters:

parameter - the parameter name.

parameters - the map with parameter name/value pairs.

defaultParameters - the map with default parameter name/value pairs.

Returns:

the parameter value.

getDoubleParameterValue

public static double getDoubleParameterValue(String parameter,
                                             Map<String,String> parameters,
                                             Map<String,String> defaultParameters)

Returns a double parameter.

Parameters:

parameter - the parameter name.

parameters - the map with parameter name/value pairs.

defaultParameters - the map with default parameter name/value pairs.

Returns:

the parameter value.

getIntParameterValue

public static int getIntParameterValue(String parameter,
                                       Map<String,String> parameters,
                                       Map<String,String> defaultParameters)

Returns an int parameter.

Parameters:

parameter - the parameter name.

parameters - the map with parameter name/value pairs.

defaultParameters - the map with default parameter name/value pairs.

Returns:

the parameter value.

getParameterValue(java.lang.String, java.util.Map, java.util.Map)

verifyDescriptor

public static boolean verifyDescriptor(GestureSet set,
                                       Class<? extends Descriptor> descriptorType)

Returns true if all Gesture Classes of the Gesture Set have the required descriptor. As soon that one Class does not fulfill the requirements the result is false.

Parameters:

set - the gesture set to test.

descriptorType - the descriptor type.

Returns:

true if all gesture classes of the gesture set have the specified descriptor.
