Method Summary
Modifier and TypeMethodDescriptionaddParameter
(String parameterName, String value) Adds a parameter value.addParameterValue
(String parameterName, Object value) Adds a parameter value as a value object; the value object is converted to a string via ContextPathEncoder.encodeValue(Object) from tapestry-core and the result is added viaLink.addParameter(String, String)
.copyWithBasePath
(String basePath) Creates a copy of this link that has the same parameters, anchor, and other attributes, but a different base path.Returns the link anchor.Returns the completely unadorned base path.Returns the names of any additional query parameters for the URI.getParameterValue
(String name) Returns the value of a specifically named query parameter, ornull
if no such query parameter is stored in the link.String[]
getParameterValues
(String parameterName) Returns the parameter values for the given name.Returns the current security for this link, which reflects whether the targeted page is itself secure or insecure.removeParameter
(String parameterName) Removes a parameter value, which is occasionally useful when transforming a parameter into a portion of the path.Sets the link anchor.void
setSecurity
(LinkSecurity newSecurity) Changes the link's security, which can be useful to force a link to be either secure or insecure when normally it might not be.Returns the absolute URL, which includes the scheme, hostname and possibly port (as perBaseURLSource.getBaseURL(boolean)
).toAbsoluteURI
(boolean secure) Returns either the secure or insecure URL, with complete scheme, hostname and possibly port (as perBaseURLSource.getBaseURL(boolean)
).Returns the link as a redirect URI.toString()
Returns the value fromtoURI()
toURI()
Returns the URI portion of the link.

Method Details
-
copyWithBasePath
Description copied from interface:Link
Creates a copy of this link that has the same parameters, anchor, and other attributes, but a different base path.- Specified by:
copyWithBasePath
in interfaceLink
- Returns:
- a new Link instance
-
addParameter
Description copied from interface:Link
Adds a parameter value. The value will be added, as is, to the URL. In many cases, the value should be URL encoded viaURLCodec
.- Specified by:
addParameter
in interfaceLink
- Parameters:
parameterName
- the name of the parameter to storevalue
- the value to store, a null or blank value is allowed (as of Tapestry 5.3)- Returns:
- this Link, to support method chaining
-
getBasePath
Description copied from interface:Link
Returns the completely unadorned base path. Other methods (such asLink.toURI()
), may append an anchor or query parameters.- Specified by:
getBasePath
in interfaceLink
-
removeParameter
Description copied from interface:Link
Removes a parameter value, which is occasionally useful when transforming a parameter into a portion of the path.- Specified by:
removeParameter
in interfaceLink
- Returns:
- this Link, to support method chaining
-
getAnchor
Description copied from interface:Link
Returns the link anchor. If this link does not have an anchor, this method returnsnull
. -
getParameterNames
Description copied from interface:Link
Returns the names of any additional query parameters for the URI. Query parameters store less regular or less often used values that can not be expressed in the path. They also are used to store, or link to, persistent state.- Specified by:
getParameterNames
in interfaceLink
- Returns:
- list of query parameter names, is alphabetical order
-
getParameterValue
Description copied from interface:Link
Returns the value of a specifically named query parameter, ornull
if no such query parameter is stored in the link. Use this method only when you are sure the parameter has only one value. If the parameter might have more than one value, useLink.getParameterValues(java.lang.String)
. If you use this method with a multivalued parameter, the value returned is equal to the first value in the array returned bygetParameterValues
.- Specified by:
getParameterValue
in interfaceLink
- Returns:
- a string representing the single value of the named parameter
-
setAnchor
Description copied from interface:Link
Sets the link anchor. Null and empty anchors will be ignored when building the link URI. -
toAbsoluteURI
Description copied from interface:Link
Returns the absolute URL, which includes the scheme, hostname and possibly port (as perBaseURLSource.getBaseURL(boolean)
). By default, the scheme is chosen to match the security of the current request. Note: the semantics of this method changed between Tapestry 5.1 and 5.2. Most code should use toString() orLink.toURI()
(which are equivalent) instead.- Specified by:
toAbsoluteURI
in interfaceLink
- Returns:
- the complete, qualified URL, including query parameters.
-
toAbsoluteURI
Description copied from interface:Link
Returns either the secure or insecure URL, with complete scheme, hostname and possibly port (as perBaseURLSource.getBaseURL(boolean)
).- Specified by:
toAbsoluteURI
in interfaceLink
- Returns:
- the complete, qualified URL, including query parameters.
-
setSecurity
Description copied from interface:Link
Changes the link's security, which can be useful to force a link to be either secure or insecure when normally it might not be.- Specified by:
setSecurity
in interfaceLink
- Parameters:
newSecurity
- new security value, not null, typicallyLinkSecurity.FORCE_SECURE
orLinkSecurity.FORCE_INSECURE
-
getSecurity
Description copied from interface:Link
Returns the current security for this link, which reflects whether the targeted page is itself secure or insecure.- Specified by:
getSecurity
in interfaceLink
-
toRedirectURI
Description copied from interface:Link
Returns the link as a redirect URI. The URI includes any query parameters.- Specified by:
toRedirectURI
in interfaceLink
-
toURI
Description copied from interface:Link
Returns the URI portion of the link. When the link is created for a form, this will not include query parameters. This is the same value returned from toString(). -
toString
Returns the value fromtoURI()
-
addParameterValue
Description copied from interface:Link
Adds a parameter value as a value object; the value object is converted to a string via ContextPathEncoder.encodeValue(Object) from tapestry-core and the result is added viaLink.addParameter(String, String)
. The Link object is returned for further configuration.- Specified by:
addParameterValue
in interfaceLink
-
getParameterValues
Description copied from interface:Link
Returns the parameter values for the given name. Returns null if no such parameter is stored in the link.- Specified by:
getParameterValues
in interfaceLink
-
