java.lang.String	toString() Return a human-readable description for this PofUpdater.
void	update(java.lang.Object oTarget, java.lang.Object oValue) Update the passed target object using the specified value.
void	writeExternal(PofWriter out) Save the contents of a POF user type instance by writing its state using the specified PofWriter object.

Constructor Detail

PofUpdater

public PofUpdater()

Default constructor (necessary for the PortableObject interface).

PofUpdater

public PofUpdater(int iProp)

Constructs a PofUpdater based on a property index. <p/> This constructor is equivalent to:

   PofUpdater updater =
       new PofUpdater(new SimplePofPath(iProp));
 

Parameters:

iProp - property index

PofUpdater

public PofUpdater(PofNavigator navigator)

Constructs a PofUpdater based on a POF navigator.

Parameters:

navigator - POF navigator

Method Detail

update

public void update(java.lang.Object oTarget,
                   java.lang.Object oValue)

Update the passed target object using the specified value. <p/> It is expected that this updater will only be used against POF-encoded entries implementing BinaryEntry interface.

Specified by:

update in interface ValueUpdater

Parameters:

oTarget - the Object to update

oValue - the new value to update the target's property with

Throws:

java.lang.UnsupportedOperationException - if the specified target object is not a POF-encoded BinaryEntry or the serializer is not a PofContext

java.lang.NullPointerException - if the property cannot be resolved

equals

public boolean equals(java.lang.Object o)

Compare the PofUpdater with another object to determine equality.

Returns:

true iff this PofUpdater and the passed object are equivalent PofUpdaters

hashCode

public int hashCode()

Determine a hash value for the PofUpdater object according to the general Object.hashCode() contract.

Returns:

an integer hash value for this PofUpdater object

toString

public java.lang.String toString()

Return a human-readable description for this PofUpdater.

Returns:

a String description of the PofUpdater

readExternal

public void readExternal(PofReader in)
                  throws java.io.IOException

Restore the contents of a user type instance by reading its state using the specified PofReader object.

Specified by:

readExternal in interface PortableObject

Parameters:

in - the PofReader from which to read the object's state

Throws:

java.io.IOException - if an I/O error occurs

writeExternal

public void writeExternal(PofWriter out)
                   throws java.io.IOException

Save the contents of a POF user type instance by writing its state using the specified PofWriter object.

Specified by:

writeExternal in interface PortableObject

Parameters:

out - the PofWriter to which to write the object's state

Throws:

java.io.IOException - if an I/O error occurs
