Constructor Detail

ManagedPropertyImpl

public ManagedPropertyImpl(PropertyHandler handler,
                           Property property,
                           int index)

Creates a new instance.

Parameters:

handler - the handler responsible for encoding and decoding snapshot values

property - the reflection property

index - the index position of this property in the managed entity

Method Detail

getIndex

public int getIndex()

Description copied from interface: ManagedProperty

Returns the index position of the property. When exchanging partial snapshots Pimento send only the index position and not the property name as the identifier to save some bandwith.

Specified by:

getIndex in interface ManagedProperty

Returns:

the index position of the property

getHandler

public PropertyHandler getHandler()

Description copied from interface: ManagedProperty

The handler of the property, responsible for converting values to and from snapshots.

Specified by:

getHandler in interface ManagedProperty

Returns:

the handler of the property, responsible for converting values to and from snapshots.

getProperty

public Property getProperty()

Description copied from interface: ManagedProperty

Returns the reflection type of the managed property.

Specified by:

getProperty in interface ManagedProperty

Returns:

the reflection type of the managed property.

isRefreshable

public boolean isRefreshable()

Description copied from interface: ManagedProperty

Indicates whether this property is refreshable from the perspective of the client. A refreshable property will be automatically synchronized in the client whenever that client persists or merges an entity that contains such a property. It does not synchronize other connected clients though.

Specified by:

isRefreshable in interface ManagedProperty

Returns:

true if this property is refreshable from the perspective of the client

isReadOnly

public boolean isReadOnly()

Description copied from interface: ManagedProperty

Indicates whether this property is read-only from the perspective of the client. If this property is true any attempt from a Flex/Flash client to change the property value will lead to an Exception. Changes caused by Java code are not affected by this setting.

Specified by:

isReadOnly in interface ManagedProperty

Returns:

true if this property is read-only from the perspective of the client

readExternal

public void readExternal(DataInput input)

Description copied from interface: Externalizable

Restores the content of this object from the DataInput instance. Values must be read in the same sequence as they were written on the client side.

Specified by:

readExternal in interface Externalizable

Parameters:

input - the AMF3 data to read from

writeExternal

public void writeExternal(DataOutput output)

Description copied from interface: Externalizable

Saves the content of this object to the DataOutput instance.

Specified by:

writeExternal in interface Externalizable

Parameters:

output - the output to write to
