--------------------------------------------
Summary: Provide Helper Methods for parsing Map<String,Object>
configurations
Key: STANBOL-1346
URL: https://issues.apache.org/jira/browse/STANBOL-1346
Project: Stanbol
Issue Type: Improvement
Components: Enhancer
Reporter: Rupert Westenthaler
Assignee: Rupert Westenthaler
Fix For: 1.0.0, 0.12.1
This issue tracks improvements to the EnhancementEngineHelper implemented as
part of STANBOL-488 (EnhancementProperties) and STANBOL-1334, STANBOL-1334
(DereferenceEngine) that are also useful for any other EnhancementEngine that
requires to parse
* OSGI component configuration (using Dictionary<String,Object>)
* Enhancement properties (using Map<String, Object>).
The EnhancementEngineHelper will be extended by the following type of static
utility methods
{code}
+ parseConfigValues(Object value, Class<T> type) : Collection<T>
+ parseFistConfigValue(Object value, Class<T> type) : T
+ getConfigValues(Dictionary<String,Object> config, String property,
Class<T> type) : Collection<T>
+ getConfigValues(EnhancementEngine ee, ContentItem ci,
Map<String,Object> enhProp, String property, Class<T> type)
Collection<T>
{code}
All methods will:
* return NULL if NULL is parsed as config value or the parsed configuration
does not contain the requested property
* support Arrays and Collections for multiple values.
* support Arrays of primitive types
Additional optional parameters (for all methods)
* {noformat}String preserveNullValues{noformat}: if null values should be
preserved. By default those will get removed.
* {noformat}Collection<T> addTo{noformat}: Allows to parse the collection to be
filled with the configuration values
