| org.archive.crawler.framework.CrawlScope
 org.archive.crawler.scope.ClassicScope
All known Subclasses: org.archive.crawler.scope.SeedCachingScope, org.archive.crawler.scope.BroadScope, org.archive.crawler.scope.RefinedScope,
| ClassicScope | | public class ClassicScope extends CrawlScope (Code) | | ClassicScope: superclass with shared Scope behavior for
most common scopes.
Roughly, its logic is captured in innerAccept(). A URI is
included if:
forceAccepts(uri)
|| (((isSeed(uri)
|| focusAccepts(uri))
|| additionalFocusAccepts(uri)
|| transitiveAccepts(uri))
&& !excludeAccepts(uri));
Subclasses should override focusAccepts, additionalFocusAccepts,
and transitiveAccepts.
The excludeFilter may be specified by supplying
a exclude subelement. If unspecified, a
accepts-none filter will be used -- meaning that
no URIs will pass the filter and thus be excluded.

| Method Summary | |
| protected boolean | additionalFocusAccepts(Object o)
Check if URI is accepted by the additional focus of this scope.
This method should be overridden in subclasses.
Parameters:
o - the URI to check. | | protected boolean | exceedsMaxHops(Object o)
Check if there are too many hops
Parameters:
o - URI to check. | | protected boolean | excludeAccepts(Object o)
Check if URI is excluded by any filters.
Parameters:
o - the URI to check. | | protected boolean | focusAccepts(Object o)
Check if URI is accepted by the focus of this scope.
This method should be overridden in subclasses.
Parameters:
o - the URI to check. | | protected boolean | forceAccepts(Object o)
Parameters:
o - the URI to check. | | final protected boolean | innerAccepts(Object o)
Returns whether the given object (typically a CandidateURI) falls within
this scope.
Parameters:
o - Object to test. | | public void | kickUpdate()
Take note of a situation (such as settings edit) where involved
reconfiguration (such as reading from external files) may be necessary. | | protected boolean | transitiveAccepts(Object o)
Parameters:
o - the URI to check. |

| ClassicScope | | public ClassicScope(String name)(Code) | |
Parameters:
name - ignored by superclass |

|
| additionalFocusAccepts | | protected boolean additionalFocusAccepts(Object o)(Code) | | Check if URI is accepted by the additional focus of this scope.
This method should be overridden in subclasses.
Parameters:
o - the URI to check. True if additional focus filter accepts passed object. |
| exceedsMaxHops | | protected boolean exceedsMaxHops(Object o)(Code) | | Check if there are too many hops
Parameters:
o - URI to check. true if too many hops. |
| excludeAccepts | | protected boolean excludeAccepts(Object o)(Code) | | Check if URI is excluded by any filters.
Parameters:
o - the URI to check. True if exclude filter accepts passed object. |
| focusAccepts | | protected boolean focusAccepts(Object o)(Code) | | Check if URI is accepted by the focus of this scope.
This method should be overridden in subclasses.
Parameters:
o - the URI to check. True if focus filter accepts passed object. |
| forceAccepts | | protected boolean forceAccepts(Object o)(Code) | |
Parameters:
o - the URI to check. True if force-accepts filter accepts passed object. |
| innerAccepts | | final protected boolean innerAccepts(Object o)(Code) | | Returns whether the given object (typically a CandidateURI) falls within
this scope.
Parameters:
o - Object to test. Whether the given object (typically a CandidateURI) falls withinthis scope. |
| kickUpdate | | public void kickUpdate()(Code) | | Take note of a situation (such as settings edit) where involved
reconfiguration (such as reading from external files) may be necessary.
|
| transitiveAccepts | | protected boolean transitiveAccepts(Object o)(Code) | |
Parameters:
o - the URI to check. True if transitive filter accepts passed object. |
