Method Detail

acceptsGzip

public static boolean acceptsGzip(javax.servlet.http.HttpServletRequest httpServletRequest)

getAccept

public static java.lang.String getAccept(javax.servlet.http.HttpServletRequest httpServletRequest)

getBrowserId

public static java.lang.String getBrowserId(javax.servlet.http.HttpServletRequest httpServletRequest)

getBrowserMetadata

public static com.liferay.portal.kernel.servlet.BrowserMetadata getBrowserMetadata(javax.servlet.http.HttpServletRequest httpServletRequest)

getMajorVersion

public static float getMajorVersion(javax.servlet.http.HttpServletRequest httpServletRequest)

Returns the browser's version number as a float. This differs from BrowserSniffer#getVersion(HttpServletRequest), which returns the version number as a String.

Note that the version returned is defined as the real version of the browser software, not the one used to render the page. For example, the browser can be IE10 but it may be using a compatibility view emulating IE8 to render the page. In such a case, this method would return 10.0, not 8.0.

Parameters:

httpServletRequest - the servlet request

Returns:

a float representing the version number

getRevision

public static java.lang.String getRevision(javax.servlet.http.HttpServletRequest httpServletRequest)

Returns the browser's revision.

Note that the revision returned is defined as the real revision of the browser software, not the one used to render the page. For example, the browser can be IE10 but it may be using a compatibility view emulating IE8 to render the page. In such a case, this method would return 10.0, not 8.0.

Parameters:

httpServletRequest - the servlet request

Returns:

a String containing the revision number

getVersion

public static java.lang.String getVersion(javax.servlet.http.HttpServletRequest httpServletRequest)

Returns the browser's version.

Note that the version returned is defined as the real version of the browser software, not the one used to render the page. For example, the browser can be an IE10 but it may be using a compatibility view emulating IE8 to render the page. In such a case, this method would return 10.0, not 8.0.

Parameters:
