Method Detail

getType

public static <T> T getType(Class<T> targetType,

Type Parameters:

T - the type to return

Parameters:

source - the string value to convert

targetType - target type

the object instance

isConvertable

public static boolean isConvertable(Class<?> targetType)

Tests if the class can safely be converted from a String to the specified type.

Parameters:

targetType - the type to convert to

Returns:

true if the class possesses either a "valueOf()" method or a constructor with a String parameter.

• Yes
• Y
• T
• 1

While the following values will return false:

• No

• F
• 0

Parameters:

source - source string

Returns:

boolean value from string

getTypeViaValueOfMethod

public static <T> T getTypeViaValueOfMethod(String source,
                                            Class<T> targetType)
                                     throws NoSuchMethodException

Type Parameters:

T - type
