getUID
Description copied from class:ALcyWorkspaceObjectCodec
A unique identifier for thisALcyWorkspaceObjectCodec
. The UID will be used to make sure that a workspace part that is encoded by aALcyWorkspaceObjectCodec
with some UID can only be decoded by aALcyWorkspaceObjectCodec
with the same UID. For this purpose it is mandatory that, whenever the application is restarted,ALcyWorkspaceObjectCodec
's with the same UID's are registered with theTLcyWorkspaceManager
. Unique means that at any time no twoALcyWorkspaceObjectCodec
s orALcyWorkspaceCodecDelegate
s with the samegetUID()
must be registered with the sameTLcyWorkspaceManager
. Therefore it is suggested to use a package name prefix for the UID's. The UID's of allALcyWorkspaceCodecDelegate
s added by Lucy itself start with "com.luciad". The UID must not be 'null', must not be the empty string "", must not contain spaces and must not start with '%'- Specified by:
getUID
in classALcyWorkspaceObjectCodec
- Returns:
- The UID for this
ALcyWorkspaceObjectCodec
.
-
canEncodeObject
Description copied from class:ALcyWorkspaceObjectCodec
This method returns true if the givenObject
can be encoded, false otherwise. This method should only be invoked by anALcyWorkspaceCodec
, never by user code. Instead user code must useALcyWorkspaceCodec.canEncodeReference(Object, Object)
when an object reference needs to be restored.- Specified by:
canEncodeObject
in classALcyWorkspaceObjectCodec
- Parameters:
aWSCodec
- TheALcyWorkspaceCodec
, provided in case object references need to be stored.aObject
- The object to encode.aParent
- The parent of the object to encode. The parent will often be null, or for example when a domain objects needs to be saved (e.g. a polyline), the parent will normally be theILcdModel
that contains the domain object. The exact value of the parent is defined by theALcyWorkspaceObjectCodec
that will encode the object. Please check the javadoc of the addon responsible for the object to encode or refer to the Lucy Developer Guide for more information.- Returns:
- True if the given
Object
can be encoded, false otherwise.
-
encodeObject
public void encodeObject(ALcyWorkspaceCodec aWSCodec, Object aObject, Object aParent, OutputStream aOut) throws IOException, TLcyWorkspaceAbortedException Description copied from class:ALcyWorkspaceObjectCodec
This method writes the givenObject
to the givenOutputStream
. This method should only be invoked by anALcyWorkspaceCodec
, never by user code. Instead user code must useALcyWorkspaceCodec.encodeReference(Object, Object)
when an object reference needs to be stored. Note that this method must, in general, be re-entrant: this method can be invoked by a thread before the previous call on that same thread is terminated. This happens when this method stores references (ALcyWorkspaceCodec.encodeReference(Object, Object)
) to objects that are encoded by this codec as well. Or if it stores references to objects that (indirectly) refer objects that are encoded by this codec.- Specified by:
encodeObject
in classALcyWorkspaceObjectCodec
- Parameters:
aWSCodec
- TheALcyWorkspaceCodec
, provided in case object references need to be stored.aObject
- The object to encode.aParent
- The parent of the object to encode. The parent will often be null, or for example when a domain objects needs to be saved (e.g. a polyline), the parent will normally be theILcdModel
that contains the domain object. The exact value of the parent is defined by theALcyWorkspaceObjectCodec
that will encode the object. Please check the javadoc of the addon responsible for the object to encode or refer to the Lucy Developer Guide for more information.aOut
- TheOutputStream
to write to.- Throws:
IOException
- In case of IO failure.TLcyWorkspaceAbortedException
- In case the user aborted (e.g. canceled) the operation.
-
createObject
public Object createObject(ALcyWorkspaceCodec aWSCodec, Object aParent, InputStream aIn) throws IOException, TLcyWorkspaceAbortedException Description copied from class:ALcyWorkspaceObjectCodec
This method creates anObject
of the proper class. The returned object will then be further initialized byALcyWorkspaceObjectCodec.decodeObject(ALcyWorkspaceCodec, Object, Object, java.io.InputStream)
. The decoding of an object is split intocreateObject
anddecodeObject
to be able to deal with circular references. DuringcreateObject
ALcyWorkspaceCodec.decodeReference(String)
must not be used to resolve circular references. Actually it is advised not to useALcyWorkspaceCodec.decodeReference(String)
at all from this method. This method should only be invoked by anALcyWorkspaceCodec
, never by user code. Instead user code must useALcyWorkspaceCodec.decodeReference(String)
when an object reference needs to be restored.- Specified by:
createObject
in classALcyWorkspaceObjectCodec
- Parameters:
aWSCodec
- TheALcyWorkspaceCodec
.aParent
- The parent of the object to decode. The parent will often be null, or for example when a domain objects needs to be restored (e.g. a polyline), the parent will normally be theILcdModel
that must contain the domain object. The exact value of the parent is defined by theALcyWorkspaceObjectCodec
that will decode the object. Please check the javadoc of the addon responsible for the object to decode or refer to the Lucy Developer Guide for more information.aIn
- TheInputStream
. Normally this method will not read from the input stream!- Returns:
- The created object.
- Throws:
IOException
- In case of IO failure.TLcyWorkspaceAbortedException
- In case the user aborted (e.g. canceled) the operation.
-
decodeObject
public void decodeObject(ALcyWorkspaceCodec aWSCodec, Object aObject, Object aParent, InputStream aIn) throws IOException, TLcyWorkspaceAbortedException Description copied from class:ALcyWorkspaceObjectCodec
This method decodes the properties of anObject
created byALcyWorkspaceObjectCodec.createObject(ALcyWorkspaceCodec, Object, java.io.InputStream)
from the givenInputStream
. The decision if this codec can read from theInputStream
is based on theALcyWorkspaceObjectCodec.getUID()
of this codec. If theObject
was written by a codec with the same UID as this codec, it is assumed that this codec can read from theInputStream
. The decoding of an object is split intocreateObject
anddecodeObject
to be able to deal with circular references. Preferably object references should be restored from this method. (by usingALcyWorkspaceCodec.decodeReference(String)
). There are however a lot of codecs which don't need to do anything in this method. Therefore this method is not abstract, and the default implementation does nothing. This method should only be invoked by anALcyWorkspaceCodec
, never by user code. Instead user code must useALcyWorkspaceCodec.decodeReference(String)
when an object reference needs to be restored. Note that this method must, in general, be re-entrant: this method can be invoked by a thread before the previous call on that same thread is terminated. This happens when this method restores references (ALcyWorkspaceCodec.decodeReference(String)
) to objects that are decoded by this codec as well. Or if it restores references to objects that (indirectly) refer objects that are decoded by this codec.- Overrides:
decodeObject
in classALcyWorkspaceObjectCodec
- Parameters:
aWSCodec
- TheALcyWorkspaceCodec
, provided in case object references need to be restored.aObject
- The object to decode the properties of. It was created usingALcyWorkspaceObjectCodec.createObject(ALcyWorkspaceCodec, Object, java.io.InputStream)
.aParent
- The parent of the object to decode. The parent will often be null, or for example when a domain objects needs to be restored (e.g. a polyline), the parent will normally be theILcdModel
that must contain the domain object. The exact value of the parent is defined by theALcyWorkspaceObjectCodec
that will decode the object. Please check the javadoc of the addon responsible for the object to decode or refer to the Lucy Developer Guide for more information.aIn
- TheInputStream
to read from.- Throws:
IOException
- In case of IO failure.TLcyWorkspaceAbortedException
- In case the user aborted (e.g. canceled) the operation.
