Method Detail

values

public static ValueType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ValueType c : ValueType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ValueType valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

fromObject

public static ValueType fromObject(java.lang.Object object)

Converts an arbitrary object to a value type.

Parameters:

object - the object to be converted

Returns:

the value type (default OBJECT)

write

public void write(java.io.DataOutputStream out,
                  java.lang.Object value)
           throws java.io.IOException

Writes a corresponding value to the given input stream.

Parameters:

out - the output stream

value - a corresponding (castable) value

Throws:

java.io.IOException - in case of any I/O related error

java.lang.ClassCastException - in case that value does not map to the respective wrapper classes

read

public java.lang.Object read(java.io.DataInputStream in)
                      throws java.io.IOException

Reads a corresponding value from the given input stream.

Parameters:

in - the input stream

Returns:

the corresponding value (may be null)

Throws:

java.io.IOException - in case of any I/O related error
