Configuration (datavec-api 0.9.1 API)

java.lang.Object
- org.datavec.api.conf.Configuration

All Implemented Interfaces:

Serializable, Iterable<Map.Entry<String,String>>, Writable
```
public class Configuration
extends Object
implements Iterable<Map.Entry<String,String>>, Writable, Serializable
```
Provides access to configuration parameters.
Resources

Configurations are specified by resources. A resource contains a set of name/value pairs as XML data. Each resource is named by either a String. If named by a String, then the classpath is examined for a file with that name. If named by a Path, then the local filesystem is examined directly, without referring to the classpath.
Unless explicitly turned off, Hadoop by default specifies two resources, loaded in-order from the classpath:
1. core-default.xml: Read-only defaults for hadoop.
2. core-site.xml: Site-specific configuration for a given hadoop installation.
Applications may add additional resources, which are loaded subsequent to these resources in the order they are added.
Final Parameters

Configuration parameters may be declared final. Once a resource declares a value final, no subsequently-loaded resource can alter that value. For example, one might define a final parameter with:
```
 <property>
 <name>dfs.client.buffer.dir</name>
 <value>/tmp/hadoop/dfs/client</value>
 <final>true</final>
 </property>
```
Administrators typically define parameters as final in core-site.xml for values that user applications may not alter.
Variable Expansion

Value strings are first processed for variable expansion. The available properties are:
1. Other properties defined in this Configuration; and, if a name is undefined here,
2. Properties in System.getProperties().
For example, if a configuration resource contains the following property definitions:
```
 <property>
 <name>basedir</name>
 <value>/user/${user.name}</value>
 </property>

 <property>
 <name>tempdir</name>
 <value>${basedir}/tmp</value>
 </property>
```
When conf.get("tempdir") is called, then ${basedir} will be resolved to another property in this Configuration, while ${user.name} would then ordinarily be resolved to the value of the System property with that name.
