Method Details

getProperJavaClass

public static String getProperJavaClass(String _argType,
 Set<String> _includes)

Converts a java class type to another type. This is used for converting e.g. CharSequence to String etc. It will also remove unnecessary package names like java.lang.

Parameters:

_argType - Argument to convert

_includes - Set where additional includes will be added (should never be null!)

Returns:

String with proper type, if no converation could be done, original input is returned

convertJavaType

public static String convertJavaType(String _fqcn,
 boolean _usePrimitives)

Transform certain java types to other java types (see CLASS_MAP).

Parameters:

_fqcn - fully qualified classname of the type to convert

_usePrimitives - if true, boxed types will be converted to primitives

Returns:

converted type or original input

convertJavaBoxedTypeToPrimitive

private static String convertJavaBoxedTypeToPrimitive(String _clazzName)

Converts certain boxed types to primitives.

Parameters:

_clazzName - class name of boxed type

Returns:

primitive or original input

getJavaTypeFromDBusType

public static String getJavaTypeFromDBusType(String _dbusType,
 Set<String> _javaIncludes)
                                      throws DBusException

Converts a DBus data type string to java classname(s).

Parameters:

_dbusType - DBus data type string

_javaIncludes - List where additional imports will be added to (should not be null!)

Returns:

Java classname, maybe null if no suitable input was given

Throws:

DBusException - on DBus error

getTypeAdv

private static Map<String,List<String>> getTypeAdv(Type _type)
                                            throws DBusException

Resolve java type recursively.

Parameters:

_type - Type object

Returns:

Map where key is parent classname (e.g. List) and value is a list of types used inside the generics

Throws:

DBusException - on error

getTypeAdv

private static String getTypeAdv(String _dbusType,
 Set<String> _javaIncludes)
                          throws DBusException

Special handling for DBusMapType and DBusListType.

Parameters:

_dbusType - DBus type string

_javaIncludes - list where additional java imports are added to (if any)

Returns:

class name of the parent type, maybe null if no suitable input provided

Throws:

DBusException
