Annotation Type MIMEResolver.NamespaceRegistration

@Retention(value=SOURCE)
public static @interface MIMEResolver.NamespaceRegistration

Recognize mime type by looking into header of XML files. The file will be recognized by following rules:

• If the actual extension is among acceptedExtension() list, then the recognition is over and mimeType() is assigned to the file.
• If the extension is not among the list of extensions to check (which by default contains "xml"), then the recognition is over without recognizing any mime type.
• If the document contains one of requested public ID, then the mime type is recognized and the recognition ends.
• If the root element is not equal to specified elementName(), then the recognition is over without recognizing the mime type.
• If the list of elementNS() namespaces is specified and the namespace of the root element is not among the list, then the recognition is over and no mime type is recognized.
• If all the above, passed OK, the mimeType() is recognized.

If you want to recognize file just by its extension consider using MIMEResolver.ExtensionRegistration.

Element Detail

displayName

public abstract String displayName

Display name to present this type of objects to the user.

mimeType

public abstract String mimeType

Mime type to be assigned to files that match description of this annotation.

position

public abstract int position

In case ordering of mime resolvers is important, one can specify it by defining their position.

Default:

2147483647

acceptedExtension

public abstract String[] acceptedExtension

The extension that is automatically accepted. If specified, then a file with such extension automatically leads to recognition of defined mimeType().

Default:

{}

checkedExtension

public abstract String[] checkedExtension

The extension of the file to check. By default only .xml files are tested for content. One can change the extension of the file by changing the value of this attribute. Assigning an empty array to attribute turns the content check on every file

Default:

"xml"

elementName

public abstract String elementName

Name of root element. If at least one of the provided element names matches the real element name, this condition is satisfied.

Returns:

one or more element name. May be left empty, if element name should not be checked at all.

Default:

""

elementNS

public abstract String[] elementNS

Accept only elements that have specific namespace. If this attribute is specified, then only such elements are accepted that have the right namespace.

Default:

{}

doctypePublicId

public abstract String[] doctypePublicId

If this attribute is specified, the system will check whether at least one of the specified doctype's public ids, is used in the document.
