Method Detail

declaredExcelContentProperty

public static ExcelContentProperty declaredExcelContentProperty(Map<?,?> dataMap,
                                                                Class<?> headClazz,

Calculate the configuration information for the class

Parameters:

dataMap -

headClazz -

fieldName -

Returns:

combineExcelContentProperty

public static void combineExcelContentProperty(ExcelContentProperty combineExcelContentProperty,
                                               ExcelContentProperty excelContentProperty)

declaredFields

public static FieldCache declaredFields(Class<?> clazz,
                                        ConfigurationHolder configurationHolder)

Parsing field in the class

Parameters:

clazz - Need to parse the class

configurationHolder - configuration

getAllInterfaces

public static List<Class<?>> getAllInterfaces(Class<?> cls)

Gets a List of all interfaces implemented by the given class and its superclasses.

The order is determined by looking through each interface in turn as declared in the source file and following its hierarchy up. Then each superclass is considered in the same way. Later duplicates are ignored, so the order is maintained.

Parameters:

cls - the class to look up, may be null

Returns:

the List of interfaces in order, null if null input

removeThreadLocalCache

public static void removeThreadLocalCache()
