Detailed Description

Biblio::Isis implementation of IsisDb.


Constructor & Destructor Documentation

BiblioIsisDb::__construct ( schema  ) 

Constructor.

See also:

Member Function Documentation

BiblioIsisDb::backend ( method = 'count',
args = NULL 
)

Send requests to the perl backend.

Parameters:

BiblioIsisDb::charset ( &$  data  ) 

Charset conversion.

Converts a string from the database charset to UTF-8.

Parameters:
$data String to be converted.

String converted to UTF-8.
static BiblioIsisDb::check ( schema,
section = NULL 
) [static]

Check configuration.

See also:
IsisDb::check()

BiblioIsisDb::entries (  ) 

Return number of entries in the database.

See also:
IsisDb::entries()

Implements IsisDb.

BiblioIsisDb::example (  ) 

Return an example schema.

See also:
IsisDb::example()

Implements IsisDb.

BiblioIsisDb::has_subfields ( key  ) 

Checks whether a field has subfields.

Parameters:
$key Field key.
Returns:
True if has subfields, false otherwise.
BiblioIsisDb::is_repetitive ( field,
value 
)

Deals with repetition.

As Biblio::Isis always return field values as arrays, we have to check the database schema to see if we want to convert then to a single value.

Parameters:
$field Database field.
$value Data (with or without repetition).
Returns:
True if repetitive, false otherwise.
BiblioIsisDb::logger ( message  ) 

Class logger.

Parameters:
$message Log message.
BiblioIsisDb::read ( id,
method = 'fetch' 
)

Read an entry.

Parameters:
$id Record Id.
$method Database read method.
See also:
IsisDb::read()
BiblioIsisDb::repetition ( key,
value 
)

Deals with repetition.

As Biblio::Isis always return field values as arrays, we have to check the database schema to see if we want to convert then to a single value. The current implementation is just a placeholder as no conversion is done.

Parameters:
$key Database key.
$value Query field result.
Returns:
The value according to the repetition config.
BiblioIsisDb::subfields ( name,
key,
method 
)

Makes subfield substitution in a dataset.

Parameters:
$name Dataset.
$key Field key.
$method Database read method.
Returns:
Data with processed subfields.
BiblioIsisDb::subfields_from_fetch ( name,
key 
)

Subfield handling for data read by 'from_fetch' method.

Parameters:
$name Dataset.
$key Field key.
Returns:
Data with processed subfields.
BiblioIsisDb::subfields_from_to_hash ( name,
key 
)

Subfield handling for data read by 'to_hash' method. This method is not fully supported and therefore not recommended.

It does not deal very well when data has "main" fields and subfields (like "data1^adata2^bdata3") and doesn't deal with advanced configuration such as 'join_subfields'.

Parameters:
$name Dataset.
$key Field key.
Returns:
Data with processed subfields.
BiblioIsisDb::subfields_switch ( key,
&$  value 
)

Switch keys on subfields.

Parameters:
$key Field key.
$value Dataset.
BiblioIsisDb::tag ( results,
method = 'fetch' 
)

Tag results of a db query.

This function converts the keys of query result from field numbers to names.

Parameters:
$results Database query results.
$method Database read method.
Returns:
Tagged database result.
