Method Summary

void alterQuery (mixed $query)

object StorableFloat createAndPopulate (array $dbRow)

integer insert (integer $dbID)

string makeSearchString (ref $value, [int $searchType = SEARCH_TYPE_EQUALS])

void prune (integer $dbID, integer $dataID)

void update (integer $dbID, integer $dataID)

void _setValue ($value $value)

Methods

alterQuery (line 160)

Takes an existing SelectQuery and adds a table join and some columns so that when it is executed the actual data can be retrieved from the row. The join condition must be "fk_data = data_id_field", since the field "fk_data" is already part of the DataManager's table structure.

access: public

void alterQuery (mixed $query)

createAndPopulate (line 30)

Takes a single database row, which would contain the columns added by alterQuery() and extracts the values to setup the object with the appropriate data.

static:
access: public

object StorableFloat createAndPopulate (array $dbRow)

array $dbRow

insert (line 104)

Inserts a new row into the Database with the data contained in the object.

return: Returns the new ID of the data stored.
access: public

integer insert (integer $dbID)

integer $dbID: The DBHandler database ID to query.

makeSearchString (line 46)

Returns a string that could be inserted into an SQL query's WHERE clause, based on the Primitive value that is passed. It is used when searching for datasets that contain a certain field=value pair.

return: or NULL if no searching is allowed.
static:

string makeSearchString (ref $value, [int $searchType = SEARCH_TYPE_EQUALS])

int $searchType: One of the SEARCH_TYPE_* constants, defining what type of search this should be (ie, equals, contains, greater than, less than, etc)
ref $value: object $value The Primitive object to search for.

prune (line 172)

Deletes the data row from the appropriate table.

access: public

void prune (integer $dbID, integer $dataID)

integer $dbID: The DBHandler database ID to query.
integer $dataID: The ID in the database of the data to be deleted.

update (line 132)

Uses the ID passed and updates the database row with new data.

access: public

void update (integer $dbID, integer $dataID)

integer $dbID: The DBHandler database ID to query.
integer $dataID: The ID in the database of the data to be updated.

_setValue (line 94)

Set the value

since: 7/13/05
access: private

void _setValue ($value $value)

$value $value

Redefinition of:

Double::_setValue(): Set the internal value to a PHP primitive.
