Examples of org.eclipse.core.runtime.IAdapterManager.queryAdapter()

org.eclipse.core.runtime.IAdapterManager.queryAdapter()

Returns a status of an adapter factory registered that may be able to convert adaptable to an object of type adapterTypeName.

One of the following values can be returned:

{@link org.eclipse.core.runtime.IAdapterManager#NONE} if no applicable adapter factory was found;
{@link org.eclipse.core.runtime.IAdapterManager#NOT_LOADED} if an adapter factory was found, but has not been loaded;
{@link org.eclipse.core.runtime.IAdapterManager#LOADED} if an adapter factory was found, and it is loaded.

@param adaptable the adaptable object being queried (usually an instanceof IAdaptable) @param adapterTypeName the fully qualified class name of an adapter tolook up @return a status of the adapter @since org.eclipse.equinox.common 3.3
