Eclipse Platform
Release 3.5

org.eclipse.update.core.model
Class ModelObject

java.lang.Object
  extended by 

org.eclipse.core.runtime.PlatformObject
      extended by 
org.eclipse.update.core.model.ModelObject
All Implemented Interfaces:
IAdaptable
Direct Known Subclasses:
ArchiveReferenceModel, CategoryModel, ContentEntryModel, FeatureModel, FeatureReferenceModel, ImportModel, InstallHandlerEntryModel, SiteModel, URLEntryModel

Deprecated. The org.eclipse.update component has been replaced by Equinox p2. This provisional API was never promoted to stable API, and may be removed from a future release of the platform.

public abstract class ModelObject
extends PlatformObject

Root model object. Extended by all model objects.

This class cannot be instantiated and must be subclassed.

Note: This class/interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is being made available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

ModelObject

protected ModelObject()
Deprecated. 
Creates a base model object.

Since:
2.0
Method Detail

assertIsWriteable

Checks that this model object is writeable. A runtime exception is thrown if it is not.

Since:
2.0

markReadOnly

public void markReadOnly()
Deprecated. 
Sets this model object and all of its descendents to be read-only. Subclasses may extend this implementation.

Since:
2.0
See Also:
isReadOnly()

isReadOnly

public boolean isReadOnly()
Deprecated. 
Returns whether or not this model object is read-only.

Returns:
true if this model object is read-only, false otherwise
Since:
2.0
See Also:
markReadOnly()

markReferenceReadOnly

protected void markReferenceReadOnly(
ModelObject o)
Deprecated. 
Delegate setting of read-only

Parameters:
o - object to delegate to. Must be of type ModelObject.
Since:
2.0
See Also:
isReadOnly()

markListReferenceReadOnly

protected void markListReferenceReadOnly(
ModelObject[] o)
Deprecated. 
Delegate setting of read-only

Parameters:
o - object array to delegate to. Each element must be of type ModelObject.
Since:
2.0
See Also:
isReadOnly()

resolve

public void resolve(
URL base,
                    
URL bundleURL)
             throws 
MalformedURLException
Deprecated. 
Resolve the model element. This method allows any relative URL strings to be resolved to actual URL. It also allows any translatable strings to be localized. Subclasses need to override this method to perform the actual resolution.

Parameters:
base - base URL.
bundleURL - resource bundle URL.
Throws:
MalformedURLException
Since:
2.0

resolveReference

protected void resolveReference(
ModelObject o,
                                
URL url,
                                
URL bundleURL)
                         throws 
MalformedURLException
Deprecated. 
Delegate resolution to referenced model

Parameters:
o - object to delegate to. Must be of type ModelObject.
url - base URL.
bundleURL - resource bundle URL.
Throws:
MalformedURLException
Since:
2.0

resolveListReference

protected void resolveListReference(
ModelObject[] o,
                                    
URL url,
                                    
URL bundleURL)
                             throws 
MalformedURLException
Deprecated. 
Delegate resolution to list of referenced models

Parameters:
o - object array to delegate to. Each element must be of type ModelObject.
url - base URL.
bundleURL - resource bundle URL.
Throws:
MalformedURLException
Since:
2.0

resolveURL

protected 
URL resolveURL(
URL context,
                         
URL bundleURL,
                         
String urlString)
                  throws 
MalformedURLException
Deprecated. 
Resolve a URL based on context

Parameters:
context - base URL.
bundleURL - resource bundle URL.
urlString - url string from model.
Returns:
URL, or null.
Throws:

resolveNLString

protected 
String resolveNLString(
URL bundleURL,
                                 
String string)
Deprecated. 
Returns a resource string corresponding to the given argument value and bundle. If the argument value specifies a resource key, the string is looked up in the given resource bundle. If the argument does not specify a valid key, the argument itself is returned as the resource string. The key lookup is performed against the specified resource bundle. If a resource string corresponding to the key is not found in the resource bundle the key value, or any default text following the key in the argument value is returned as the resource string. A key is identified as a string begining with the "%" character. Note that the "%" character is stripped off prior to lookup in the resource bundle.

For example, assume resource bundle plugin.properties contains name = Project Name

     resolveNLString(b,"Hello World") returns "Hello World"
     resolveNLString(b,"%name") returns "Project Name"
     resolveNLString(b,"%name Hello World") returns "Project Name"
     resolveNLString(b,"%abcd Hello World") returns "Hello World"
     resolveNLString(b,"%abcd") returns "%abcd"
     resolveNLString(b,"%%name") returns "%name"
 

Parameters:
bundleURL - resource bundle url.
string - translatable string from model
Returns:
string, or null
Since:
2.0

arrayTypeFor

protected 
Object[] arrayTypeFor(
List l)
Deprecated. 
Returns a concrete array type for the elements of the specified list. The method assumes all the elements of the list are the same concrete type as the first element in the list.

Parameters:
l - list
Returns:
concrete array type, or null if the array type could not be determined (the list is null or empty)
Since:
2.0

arrayTypeFor

protected 
Object[] arrayTypeFor(
Set s)
Deprecated. 
Returns a concrete array type for the elements of the specified set. The method assumes all the elements of the set are the same concrete type as the first element in the set.
