Interface Setter

All Superinterfaces:

Getter, TxnMonitorable

All Known Implementing Classes:

AtomicSetterUtil, SetterFilter, SetterUtil

public interface Setter

extends Getter

Encapsulation of the modification of a value. Access to this interface allows one to set a value somewhere in the NODAL data system. Moreover, since it is also an extension of the Getter interface, we can query those values and request notification of changes to a value.

Method Summary

java.lang.Object	set(java.lang.Object val) Set the value to an Object.
boolean	setBoolean(boolean b) Set the value to true/false.
byte	setByte(byte b) Set the value to a byte.
char	setChar(char c) Set the value to a character.
double	setDouble(double d) Set the value to a double precision floating point value.
float	setFloat(float f) Set the value to a single precision floating point value.
int	setInt(int i) Set the value to an integer.
Node	setNode(Node n) Set the value to a Node.
short	setShort(short s) Set the value to a short integer..
java.lang.String	setString(java.lang.String s) Set the value to that parsed from a String.

Method Detail

set

public java.lang.Object set(java.lang.Object val)
                     throws ConstraintFailure

Set the value to an Object. Will call setString or setNode if appropriate.

Parameters:

val - the new value for the slot

Returns:

the Object that was Set

Throws:

ConstraintFailure

setString

public java.lang.String setString(java.lang.String s)
                           throws ConstraintFailure

Set the value to that parsed from a String.

Parameters:

s - a String representing the new value for the slot

Returns:

the String as set

Throws:

ConstraintFailure

setNode

public Node setNode(Node n)
             throws ConstraintFailure

Set the value to a Node. The Node returned should have a Path that reflects its new position in the NODAL hierarchy.

Parameters:

n - the new Node value for the slot

Returns:

a Node reference with Path defined by the Setter context

Throws:

ConstraintFailure

setBoolean

public boolean setBoolean(boolean b)
                   throws ConstraintFailure

Set the value to true/false.

Parameters:

b - the new boolean value

Returns:

the value as set

Throws:

ConstraintFailure

setChar

public char setChar(char c)
             throws ConstraintFailure

Set the value to a character.

Parameters:

c - the new character value

Returns:

the value as set

Throws:

ConstraintFailure

setByte

public byte setByte(byte b)
             throws ConstraintFailure

Set the value to a byte.

Parameters:

b - the new byte value

Returns:

the value as set

Throws:

ConstraintFailure

setShort

public short setShort(short s)
               throws ConstraintFailure

Set the value to a short integer..

Parameters:

s - the new short value

Returns:

the value as set

Throws:

ConstraintFailure

setInt

public int setInt(int i)
           throws ConstraintFailure

Set the value to an integer.

Parameters:

i - the new integer value

Returns:

the value as set

Throws:

ConstraintFailure

setFloat

public float setFloat(float f)
               throws ConstraintFailure

Set the value to a single precision floating point value.

Parameters:

f - the new float value

Returns:

the value as set

Throws:

ConstraintFailure

setDouble

public double setDouble(double d)
                 throws ConstraintFailure
