Class MIMEResolver

java.lang.Object
  org.openide.filesystems.MIMEResolver

public abstract class MIMEResolver
extends Object

Use the FileUtil.getMIMEType(org.openide.filesystems.FileObject, java.lang.String[]) to invoke the mime resolving infrastructure. All registered mime resolvers are looked up and asked one by one to resolve MIME type of passed in FileObject. Resolving is finished right after a resolver is able to resolve the FileObject or if all registered resolvers returned null (not recognized).

Use MIMEResolver.ExtensionRegistration, MIMEResolver.NamespaceRegistration or MIMEResolver.Registration to register declarative resolvers.

In the rarely case, when declarative resolvers are not sufficient, you can register subclass of MIMEResolver directly by using ServiceProvider annotation.

Nested Class Summary

static interface	MIMEResolver.ExtensionRegistration Often a mime type can be deduced just by looking at a file extension.
static interface	MIMEResolver.NamespaceRegistration Recognize mime type by looking into header of XML files.
static interface	MIMEResolver.Registration Registration that allows effective, declarative registration of complex mime resolvers.
class	MIMEResolver.UIHelpers Internal support for implementors of MIME resolver UIs.

Constructor Summary

MIMEResolver()
Deprecated. Use MIMEResolver(String...) instead. Declaring MIME types which can only be resolved by this resolver helps to speed up IDE.

Creates a new MIMEResolver.

Constructor Detail

MIMEResolver

public MIMEResolver(String... mimeTypes)

Creates a new MIMEResolver.

Parameters:

mimeTypes - an array of MIME types which can be resolved by this resolver. It should contain all MIME types which findMIMEType(org.openide.filesystems.FileObject) can return. If something is missing, this resolver can be ignored, when searching for that missing MIME type (see FileUtil.getMIMEType(FileObject, String...)).
