ConfigurationImpl (OpenJPA Parent POM 3.1.2 API)

java.lang.Object
- org.apache.openjpa.lib.conf.ConfigurationImpl

All Implemented Interfaces:

BeanInfo, Externalizable, Serializable, Cloneable, Configuration, ValueListener, Closeable

Direct Known Subclasses:

OpenJPAConfigurationImpl
```
public class ConfigurationImpl
extends Object
implements Configuration, Externalizable, ValueListener
```
Default implementation of the Configuration interface. Subclasses can choose to obtain configuration information from JNDI, Properties, a Bean-builder, etc. This class provides base configuration functionality, including serialization, the equals and hashCode contracts, and default property loading. Property descriptors for Value instances are constructed from the Localizer for the package of the configuration class. The following localized strings will be used for describing a value, where name is the last token of the value's property string:
- name-name: The name that will be displayed for the option in a user interface; required.
- name-desc: A brief description of the option; required.
- name-type: The type or category name for this option; required.
- name-expert: True if this is an expert option, false otherwise; defaults to false.
- name-values: Set of expected or common values, excluding alias keys; optional.
- name-interface: The class name of an interface whose discoverable implementations should be included in the set of expected or common values; optional.
- name-cat: The hierarchical category for the property name, separated by ".".
- name-displayorder: The order in which the property should be displayer.

IMPORTANT: If the map contains instantiated objects(rather than string values), only the string representation of those objects are considered in this configuration's equals and hashCode methods. If the object's property has no string form(such as an ObjectValue), the object is not part of the equality and hashing calculations.

  - setProperties
```
public void setProperties(String resourceName)

    Throws:
    
    IOException
  - setPropertiesFile
```
public void setPropertiesFile(File file)
                       throws IOException

```
public static String toXMLName(String propName)
```
    Convert propName to a lowercase-with-hyphens-style string. This algorithm is only designed for mixes of uppercase and lowercase letters and lone digits. A more sophisticated conversion should probably be handled by a proper parser generator or regular expressions.
  - readExternal
