Method Detail

capitalize

public static java.lang.String capitalize(java.lang.String in)

Uppercases the first letter of a string if in is not null

Parameters:

in -

Returns:

The input string with the first letter as uppercase

createPrimitiveDefaultValue

public static java.lang.Object createPrimitiveDefaultValue(java.lang.Class primitiveClass)

Creates for a primitive class an object of the corresponding object type.

Parameters:

primitiveClass -

Returns:

A newly created Object of the requested type, initialized with default values

getPrimitiveObject

public static java.lang.Object getPrimitiveObject(java.lang.Class primitive,
                                                  java.lang.String value)

Returns a new Object of the concurrent primitive type passed by primitive and initializes it with value

Parameters:

primitive -

value -

Returns:

A new Object of the concurrent primitive type, null if an error occurs

createObject

public static java.lang.Object createObject(java.lang.Class transformer,
                                            java.lang.String value)

Creates a new instances of an object, if the object has a constructor with a single String parameter

Parameters:

transformer -

value -

Returns:

A new instance of the specified class or null if an error occurs

computePrimitiveClass

public static java.lang.Class computePrimitiveClass(java.lang.Object primitive)

Retrieves for an object assignable to a primitive value the assigned primitive class type.

Parameters:

primitive -

Returns:

Primitive class type of the passed primitive object. Null if there is no primitive class for this type available
