Detailed Description

Interface for all datatypes that can be found in the database. Content objects make up a tree and each object can have a parent and children. For example, the child of an Image object is a Volume or File System. This interface defines the basic methods for reading the content associated with this object, the parent and children, and adding artifacts.

Definition at line 32 of file Content.java.

public<T> T org.sleuthkit.datamodel.Content.accept

(

ContentVisitor< T >

v

)

Visitor pattern support

Parameters

v	visitor supplying an algorithm to run on the content object

Returns

visitor return value resulting from running the algorithm

void org.sleuthkit.datamodel.Content.close

(

)

Free native resources after read is done on the Content object. After closing, read can be called again on the same Content object, which should result in re-opening of new native resources.
