Constructor Details

WebContent

public WebContent()

Method Details

contentTypeCanonical

public static String contentTypeCanonical(String contentType)

Return our "canonical" name for a Content Type. This should be the standard one, no X-*, no alternative names.

matchContentType

public static boolean matchContentType(ContentType ct1,
 ContentType ct2)

Match content type (ignores charsets and other parameters)

matchContentType

public static boolean matchContentType(String ct1,
 String ct2)

isHtmlForm

public static boolean isHtmlForm(ContentType ct)

isMultiPartForm

public static boolean isMultiPartForm(ContentType ct)

determineCT

public static ContentType determineCT(String contentTypeStr,
 Lang hintLang,
 String target)

Determine the content type to be used, given the target URL, the content-type from Content Negotiation and a hint language. This is a pragmatic balance. A content-type of "text/plain" is ignored - it is too often wrong.

The decision is

Content type (but not text/plain) > hint > file extension.

We make content type (via content negotiation) strongest because a server may return something unexpected because that is all it can do. We are assuming servers don't lie. The "hint" is really a hint just for file extension override.

In the case of no file extension, this reduces to the hint being the default choice if conneg does not produce anything useful.

Parameters:

contentTypeStr - Content-Type string

hintLang - Default language

target - The URL of the target (file extension may be used)

Returns:

ContentType or null

contentTypeToLangResultSet

public static Lang contentTypeToLangResultSet(String contentType)

Map content-type to lang for SPARQL results, with pragmatic adapters.
