Known Subclasses:: UIDCatalogBrains

Abstract base brain that handles looking up attributes as required, and provides just enough smarts to let us get the URL, path, and cataloged object without having to ask the catalog directly.

Method Summary
	`getObject(self, REQUEST)` Return the object for this record
	`getPath(self)` Get the physical path for this record
	`getRID(self)` Return the record ID for this object.
	`getURL(self, relative)` Generate a URL for this record
	`has_key(self, key)`
	`_unrestrictedGetObject(self)` Return the object for this record
Inherited from Record
	`__init__(v)` __init__([v]) -- Initialize a record, possibly with state
	`__add__(x, y)` x.__add__(y) <==> x+y
	`__cmp__(x, y)` x.__cmp__(y) <==> cmp(x,y)
	`__delattr__(...)` x.__delattr__('name') <==> del x.name
	`__delitem__(x, y)` x.__delitem__(y) <==> del x[y]
	`__delslice__(x, i, j)` Use of negative indices is not supported.
	`__getattribute__(...)` x.__getattribute__('name') <==> x.name
	`__getitem__(x, y)` x.__getitem__(y) <==> x[y]
	`__getslice__(x, i, j)` Use of negative indices is not supported.
	`__getstate__()` __getstate__() -- Get the record's data
	`__len__(x)` x.__len__() <==> len(x)
	`__mul__(x, n)` x.__mul__(n) <==> x*n
	`__new__(T, S, ...)` T.__new__(S, ...) -> a new object with type S, a subtype of T
	`__rmul__(x, n)` x.__rmul__(n) <==> n*x
	`__setattr__(...)` x.__setattr__('name', value) <==> x.name = value
	`__setitem__(x, i, y)` x.__setitem__(i, y) <==> x[i]=y
	`__setslice__(x, i, j, y)` Use of negative indices is not supported.
	`__setstate__(v)` __setstate__(v) -- Set the record's data
Inherited from Acquirer
	`__of__(context)` __of__(context) -- return the object in a context
Inherited from Base
	`__getnewargs__(...)` Get arguments to be passed to __new__
	`__reduce__(...)` Reduce an object to contituent parts for serialization
Inherited from object
	`__hash__(x)` x.__hash__() <==> hash(x)
	`__reduce_ex__(...)` helper for pickle
	`__repr__(x)` x.__repr__() <==> repr(x)
	`__str__(x)` x.__str__() <==> str(x)

Method Details

getObject(self, REQUEST=None)

Return the object for this record

Will return None if the object cannot be found via its cataloged path (i.e., it was deleted or moved without recataloging), or if the user is not authorized to access the object.

This method mimicks a subset of what publisher's traversal does, so it allows access if the final object can be accessed even if intermediate objects cannot.

getPath(self)

Get the physical path for this record

getRID(self)

Return the record ID for this object.

getURL(self, relative=0)

Generate a URL for this record

_unrestrictedGetObject(self)

Return the object for this record

Same as getObject, but does not do security checks.
