Method Detail

getTypeDescription

public static String getTypeDescription(int type)

Provide a description for the specified type. Useful for debugging, errors or presenting GUI info.

Parameters:

type - the type to get the description of

Returns:

the description of the type.

getStateDescription

public static String getStateDescription(int state)

Provide a description for the specified state. Useful for debugging, errors or presenting GUI info.

Parameters:

state - the state to get the description of

Returns:

the description of the state.

getState

public static int getState(String state)

Provide an id for the specified mmbase state description.

Parameters:

state - the state description to get the id of

Returns:

the id of the state.

getType

public static int getType(String type)

Provide an id for the specified mmbase type description

Parameters:

type - the type description to get the id of

Returns:

the id of the type.

classToType

public static int classToType(Class classType)

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 -

Returns:

an MMBase base type constant

typeToClass

public static Class typeToClass(int type)

Determines the class for a specified MMBase base type. If the value is Field.TYPE_UNKNOWN), the method returns null.

Parameters:

type -

Returns:

an MMBase base type constant

sort

public static void sort(List<? extends Field> fields,
                        int order)

getFieldTypes

public static Map<String,Field> getFieldTypes(SearchQuery query,
                                              NodeManager nm)

createSystemField

public static Field createSystemField(Cloud cloud,
                                      String name,
                                      int type)

createField

public static Field createField(Cloud cloud,
                                String name,
                                int type,
                                int state,
                                DataType dataType)

Defaulting version of #createField(String, int int, int, DataType) (no list item type, because it is nearly always irrelevant).

createField

public static Field createField(Cloud cloud,
                                String name,
                                int type,
                                int listItemType,
                                int state,
                                DataType dataType)
