Examples of Mapper

artemis.annotations.Mapper

Mapper is an object that provides an abstract interface to content repository, providing some specific operations without exposing details of the repository. It provides a mapping from application calls to the persistence layer. This isolation separates the concerns of what data accesses the application needs, in terms of domain-specific objects and data types (the public interface of the Mapper), and how these can be satisfied with a repository (the implementation of the Mapper).

Manages the different instances of the application, like the Scheduler, the PluginManager, the PullManager, GraphManager; Listens for events from these instances and executes the correct actions for those events, this way the components behind Mapper don't need to know about the others, so it should be easy for anyone to change any of those classes without affecting the entire solution.

The most dependent instance that goes beyond Mapper is GraphManager, because it has some important objects you want to access from MapApplet like the VisualizationViewer, because of that you have access to VisualizationViewer, locate a host, clear the selected hosts, and some other GraphManager methods, but you don't have direct access to it.

If you want from MapApplet to execute an action in PullManager you could access PullManager directly using the getPullManager function, this might change in the future. (sorry kinda lack of time to do this the right way)

org.apache.hadoop.mapreduce.Mapper
Maps input key/value pairs to a set of intermediate key/value pairs.
Maps are the individual tasks which transform input records into a intermediate records. The transformed intermediate records need not be of the same type as the input records. A given input pair may map to zero or many output pairs.

The Hadoop Map-Reduce framework spawns one map task for each {@link InputSplit} generated by the {@link InputFormat} for the job.Mapper implementations can access the {@link Configuration} for the job via the {@link JobContext#getConfiguration()}.
The framework first calls {@link #setup(org.apache.hadoop.mapreduce.Mapper.Context)}, followed by {@link #map(Object,Object,Context)} for each key/value pair in the InputSplit. Finally {@link #cleanup(Context)} is called.
All intermediate values associated with a given output key are subsequently grouped by the framework, and passed to a {@link Reducer} to determine the final output. Users can control the sorting and grouping by specifying two key {@link RawComparator} classes.
The Mapper outputs are partitioned per Reducer. Users can control which keys (and hence records) go to which Reducer by implementing a custom {@link Partitioner}.
Users can optionally specify a combiner, via {@link Job#setCombinerClass(Class)}, to perform local aggregation of the intermediate outputs, which helps to cut down the amount of data transferred from the Mapper to the Reducer.
Applications can specify if and how the intermediate outputs are to be compressed and which {@link CompressionCodec}s are to be used via the Configuration.

If the job has zero reduces then the output of the Mapper is directly written to the {@link OutputFormat} without sorting by keys.
Example:
```
 public class TokenCounterMapper  extends Mapper{ private final static IntWritable one = new IntWritable(1); private Text word = new Text(); public void map(Object key, Text value, Context context) throws IOException { StringTokenizer itr = new StringTokenizer(value.toString()); while (itr.hasMoreTokens()) { word.set(itr.nextToken()); context.collect(word, one); } } } 
```
Applications may override the {@link #run(Context)} method to exert greater control on map processing e.g. multi-threaded Mappers etc.

org.apache.stratum.xo.Mapper

Map an XML document to a JavaBean. The XML document is assumed to be in a common format:

 <person> <firstName>Jason</firstName> <lastName>van Zyl</lastName> <hobbies> <hobby>somnambulism</hobby> <hobby>squash</hobby> </hobbies> <address> <street>50 King</street> <city>Guelph</city> <country>Canada</country> </address> </person>

These are some of the assumptions employed to make mapping the object simpler:

Any nested objects that are created are assumed to to be in the same package as the parent object.

Processing Rules:

 Does Element refers to a noun plural? Yes: treewalk No: Does the Element have children? Yes: Create object and attach to parent, have to look for inclusion rules as we might need to create an object from another XML file. Is the parent Element a plural noun? Yes: We have a collection: addX(x) is executed No: We have a simple property: setProperty(x) is executed No: Is there an inclusion rule? Yes: Create object from an XML file and attach No: Simple String value to attach

org.docx4j.fonts.Mapper
Maps font names used in the document to fonts physically available on the system. So, a mapper per document. If fonts are added to the document (ie fonts introduced into use) then the mapper should be updated to include a mapping for the new font. There are 2 implementations: - IndentityPlusMapper, which is best where most of the fonts used in the document are physically present on the system - BestMatchingMapper, useful on Linux and OSX systems on which Microsoft fonts have not been installed. Whichever one you use, you can add/remove mappings programmatically to customise to your needs. @author jharrop

org.switchyard.component.camel.switchyard.util.Mapper
speculoos.core.Mapper
Base interface for operation on mappers. This is where most of the work is done. Conceptually, a mapper may be viewed as a function that takes an object as input, does some computation with side-effects in a given environnement, and returns a result as output object. From the point of view of the client, the fact that a mapper encapsulates communication with persistent storage medium is irrelevant.
Execution of method map occurs in a certain environment (eg. a Map) that is made of a global environment provided by the manager this mapper is part of (see fr.norsys.mapper.manager.Manage and fr.norsys.mapper.manager.Configure) and by a local environment that is passed as the second parameter of method map. The base contract is that variables defined in the local environment have precedence over values defined in the global environment.

It is a resposibility of the map implementor to ensure this contract is enforced with each call to method map.
