extractCollection
public static AbstractExtractedCollection<?,?> extractCollection(IObject collection, String specificClass, ICollectionExtractor preferredExtractor) throws SnapshotException Extracts from the heap the content of objects which represent a collection. For objects of class specifiedClass the preferredExtractor will be used, otherwise the extractor is selected internally- Parameters:
collection- an IObject representing a collection for which to extract the contentsspecificClass- a class name for which the preferred extractor should be usedpreferredExtractor- an extractor object to be used to extract the contents- Returns:
- the extracted contents
- Throws:
SnapshotException
-
extractList
Extracts from the heap the content of objects which represent a collection. The proper extractor is determined internally- Parameters:
collection- an IObject representing a List for which to extract the contents- Returns:
- ExtractedCollection the extracted contents
- Throws:
SnapshotException
-
extractMap
Extracts from the heap the content of objects which represent a Map. The proper extractor is determined internally- Parameters:
collection- an IObject representing a Map for which to extract the contents- Returns:
- ExtractedMap the extracted contents
- Throws:
SnapshotException
-
extractMap
public static ExtractedMap extractMap(IObject collection, String specificClass, IMapExtractor preferredExtractor) throws SnapshotException Extracts from the heap the content of objects which represent a Map. For objects of class specifiedClass the preferredExtractor will be used, otherwise the extractor is selected internally- Parameters:
collection- an IObject representing a Map for which to extract the contentsspecificClass- a class name for which the preferred extractor should be usedpreferredExtractor- an extractor object to be used to extract the contents- Returns:
