Interface ScalarType

All Superinterfaces:

Serializable

All Known Implementing Classes:

DoubleValue, IntValue, LongValue, NullValue, ObjectValue, StringValue

public interface ScalarType

extends Serializable

This interface makes it possible to create a new scalar type. A scalar type is responsible for being able to convert itself to any type of scalar value.

To store a custom scalar type in a scalar:

 Scalar temp = SleepUtils.getScalar(); // returns an empty scalar.
 temp.setValue(new MyScalarType()); 
 

In the above example MyScalarType is an instance that implements the ScalarType interface.

Method Summary

ScalarType	copyValue() create a clone of this scalar's value.
double	doubleValue() convert the scalar to a double
int	intValue() convert the scalar to an int
long	longValue() convert the scalar to a long
Object	objectValue() convert the scalar to an object value *shrug*
String	toString() convert the scalar to a string

Method Detail

copyValue

public ScalarType copyValue()

create a clone of this scalar's value. It is important to note that you should return a copy here unless you really want scalars of your scalar type to be passed by reference.

intValue

public int intValue()

convert the scalar to an int

longValue

public long longValue()

convert the scalar to a long

doubleValue

public double doubleValue()

convert the scalar to a double

toString

public String toString()

convert the scalar to a string

objectValue

public Object objectValue()

convert the scalar to an object value *shrug*
