Field Detail
STATE_MAXVALUE
final public static int STATE_MAXVALUE(Code)



STATE_MINVALUE
final public static int STATE_MINVALUE(Code)



TYPE_MAXVALUE
final public static int TYPE_MAXVALUE(Code)



TYPE_MINVALUE
final public static int TYPE_MINVALUE(Code)





Method Detail
classToType
public static int classToType(Class classType)(Code)
Determines the MMBase type of a specified class. The MMBase base type is sue by the storage layer to determine how to store a field. If the base type cannot be determined from the class, the value returned is Field.TYPE_UNKNOWN .
Parameters:
  classType - an MMBase base type constant



createField
public static CoreField createField(String name, int type, int listItemType, int state, DataType dataType)(Code)
Returns an instance of a CoreField based on the type and state.
Parameters:
  name - The name of the field
Parameters:
  type - the MMBase basic field type, one of the Field TYPE constants.
Parameters:
  listItemType - the MMBase type for items of a list (if type is Field.TYPE_LIST).
Parameters:
  state - the MMBase field state, one of the Field STATE constants.
Parameters:
  dataType - the dataType to use for validating the field data. If null, a default datatype is assigned



createSystemField
public static CoreField createSystemField(String name, int type)(Code)
Returns an instance of a CoreField based on the type, with state 'SYSTEM', and a basic datatype assigned.
Parameters:
  name - The name of the field
Parameters:
  type - the MMBase basic field type, one of the Field TYPE constants. Specifying Field.TYPE_LIST,may give unpredictable results.



getState
public static int getState(String state)(Code)
Provide an id for the specified mmbase state description.
Parameters:
  state - the state description to get the id of the id of the state.



getStateDescription
public static String getStateDescription(int state)(Code)
Provide a description for the specified state. Useful for debugging, errors or presenting GUI info.
Parameters:
  state - the state to get the description of the description of the state.



getType
public static int getType(String type)(Code)
Provide an id for the specified mmbase type description
Parameters:
  type - the type description to get the id of the id of the type.



getTypeDescription
public static String getTypeDescription(int type)(Code)
Provide a description for the specified type. Useful for debugging, errors or presenting GUI info.
Parameters:
  type - the type to get the description of the description of the type.



sort
public static void sort(List<CoreField> fields, int order)(Code)



typeToClass
public static Class typeToClass(int type)(Code)
Determines the class for a specified MMBase base type. If the value is Field.TYPE_UNKNOWN ), the method returns null.
Parameters:
  type - an MMBase base type constant
