simple.http.serve .ContentResolver

ContentResolver
final class ContentResolver extends Traverser (Code)
	The `ContentResolver` is used to resolve a path to a specified MIME type using a pattern. The mappings used are acquired from the `content.xml` XML file, which is located using an instance of the `Locator` object. This is used to implement a method, which allows a specific target to be matched to a MIME type without having to rely on the extension of the resource. For example, "index.xml" has the extenstion "xml" which would typiclly resolve to the MIME type "text/xml", however this type may not be desirable if the file was transformed to a type of "text/html" using XSLT. author: Niall Gallagher See Also: simple.util.Resolver

Constructor Summary
public	ContentResolver(Locator lookup) Constructor for the `ContentResolver`.

Method Summary
protected void	finish() Once all the resolve elements have been evaluated this will be used to commit the configuration.
public String	getContentType(String path) This performs the resolution using the loaded configuration file.
protected void	process(Node node) This method is used to process the resolve elements from the node object.
protected void	start() This initializes the parser so that it can be used several times.

Constructor Detail

ContentResolver
public ContentResolver(Locator lookup)(Code)
	Constructor for the `ContentResolver`. This uses a configuration file located with the `Locator` object supplied. Once the configuration file is located it is parsed and the patterns extracted are used to resolve the target paths to the matching MIME type. Parameters: lookup - the locator used to find the configuration

Method Detail

finish
protected void finish()(Code)
	Once all the resolve elements have been evaluated this will be used to commit the configuration. This method is used to acquire the number of elements that be be sucessfully read. If the size is larger than zero the resolver is validated.

getContentType
public String getContentType(String path)(Code)
	This performs the resolution using the loaded configuration file. This uses the `simple.util.Resolver` to determine whether a wild card pattern matches a specified path. If a match is found the MIME type is returned. For example, if a pattern such as `.xml` was loaded with the value `text/html` then paths such as `/path/file.xml` would be resolved to that MIME type. For details of how the resolving is done see the `simple.util.Resolver` object. Parameters:* path - this is the path that is to be resolved the MIME type that is resolved from the path

process
protected void process(Node node)(Code)
	This method is used to process the resolve elements from the node object. If the element is a resolve node then this will delegate to the `resolve` method, which will save the match and type within the internal resolver object. Parameters: node - this is a node extracted from the node object

start
protected void start()(Code)
	This initializes the parser so that it can be used several times. This clears any previous tokens extracted. This ensures that when the next `parse(String)` is invoked the list of patterns used can be updated safely.
