public TypeUtil()

方法详细资料

isPrimitive

public static boolean isPrimitive(Class<?> clazz)

getGenericType

public static <T> TypeUtil.TypeResult getGenericType(Class<T> type,
                                                     Class<? extends T> clazz)

castToString

public static String castToString(Object value)

castToByte

public static Byte castToByte(Object value)

castToChar

public static Character castToChar(Object value)

castToShort

public static Short castToShort(Object value)

castToBigDecimal

public static BigDecimal castToBigDecimal(Object value)

castToBigInteger

public static BigInteger castToBigInteger(Object value)

castToFloat

public static Float castToFloat(Object value)

castToDouble

public static Double castToDouble(Object value)

castToDate

public static Date castToDate(Object value)

isNumeric

public static boolean isNumeric(String str)

Checks if the String contains only unicode digits. A decimal point is not a unicode digit and returns false.

null will return false. An empty String ("") will return false.

 StringUtils.isNumeric(null)   = false
 StringUtils.isNumeric("")     = false
 StringUtils.isNumeric("  ")   = false
 StringUtils.isNumeric("123")  = true
 StringUtils.isNumeric("12 3") = false
 StringUtils.isNumeric("ab2c") = false
 StringUtils.isNumeric("12-3") = false
 StringUtils.isNumeric("12.3") = false
 

参数:

str - the String to check, may be null

返回:

true if only contains digits, and is non-null

parseDate

public static Timestamp parseDate(String noHasZoneAnyDateString)

castToSqlDate

public static Date castToSqlDate(Object value)

castToTimestamp

public static Timestamp castToTimestamp(Object value)

castToLong

public static Long castToLong(Object value)

castToInt

public static Integer castToInt(Object value)

castToBytes

public static byte[] castToBytes(Object value)

castToBoolean

public static Boolean castToBoolean(Object value)

cast

public static <T> T cast(Object obj,
                         Class<T> clazz)

转换类型

类型参数:

参数:

obj - 需要转换的对象

clazz - 转换至类型

返回:

转换后的对象

toLocale

public static Locale toLocale(String strVal)

castToEnum

public static <T> T castToEnum(Object obj,
                               Class<T> clazz)

cast

public static <T> T cast(Object obj,
                         Type type)

cast

public static <T> T cast(Object obj,
                         ParameterizedType type)
