Interface BaseURL

All Known Subinterfaces:

PortletURL, ResourceURL

public interface BaseURL

The BaseURL defines the basic capabilities of a portlet URL pointing back to the portlet.

Since:

2.0

Method Summary

void	addProperty(String key, String value) Adds a String property to an existing key on the URL.
Map<String,String[]>	getParameterMap() Returns a Map of the parameters currently set on this portlet URL via the setParameter or setParameters methods.
void	setParameter(String name, String value) Sets the given String parameter to this URL.
void	setParameter(String name, String[] values) Sets the given String array parameter to this URL.
void	setParameters(Map<String,String[]> parameters) Sets a parameter map for this URL.
void	setProperty(String key, String value) Sets a String property on the URL.
void	setSecure(boolean secure) Indicated the security setting for this URL.
String	toString() Returns the portlet URL string representation to be embedded in the markup. Note that the returned String may not be a valid URL, as it may be rewritten by the portal/portlet-container before returning the markup to the client.
void	write(Writer out) Writes the portlet URL to the output stream using the provided writer.
void	write(Writer out, boolean escapeXML) Writes the portlet URL to the output stream using the provided writer.

Method Detail

setParameter

void setParameter(String name,
                  String value)

Sets the given String parameter to this URL.

This method replaces all parameters with the given key.

The PortletURL implementation 'x-www-form-urlencoded' encodes all parameter names and values. Developers should not encode them.

A portlet container may prefix the attribute names internally in order to preserve a unique namespace for the portlet.

A parameter value of null indicates that this parameter should be removed.

Parameters

name - the parameter name

value - the parameter value

Throws

IllegalArgumentException - if name is null.

setParameter

void setParameter(String name,
                  String[] values)

Sets the given String array parameter to this URL.

This method replaces all parameters with the given key.

The PortletURL implementation 'x-www-form-urlencoded' encodes all parameter names and values. Developers should not encode them.

A portlet container may prefix the attribute names internally in order to preserve a unique namespace for the portlet.

Parameters

name - the parameter name

values - the parameter values

Throws

IllegalArgumentException - if name is null.

setParameters

void setParameters(Map<String,String[]> parameters)

Sets a parameter map for this URL.

All previously set parameters are cleared.

The PortletURL implementation 'x-www-form-urlencoded' encodes all parameter names and values. Developers should not encode them.

A portlet container may prefix the attribute names internally, in order to preserve a unique namespace for the portlet.

Parameters

parameters - Map containing parameter names for the render phase as keys and parameter values as map values. The keys in the parameter map must be of type String. The values in the parameter map must be of type String array (String[]).

Throws

IllegalArgumentException - if parameters is null, if any of the keys in the Map are null, if any of the keys is not a String, or if any of the values is not a String array.

setSecure

void setSecure(boolean secure)
               throws PortletSecurityException

Indicated the security setting for this URL.

Secure set to true indicates that the portlet requests a secure connection between the client and the portlet window for this URL. Secure set to false indicates that the portlet does not need a secure connection for this URL. If the security is not set for a URL, it should stay the same as the current request.

Parameters

secure - true, if portlet requests to have a secure connection between its portlet window and the client; false, if the portlet does not require a secure connection.

Throws

PortletSecurityException - if the run-time environment does not support the indicated setting

toString

String toString()

Returns the portlet URL string representation to be embedded in the markup.
Note that the returned String may not be a valid URL, as it may be rewritten by the portal/portlet-container before returning the markup to the client.

The returned URL is not XML escaped.

For writing URLs to an output stream the write(java.io.Writer) or write(java.io.Writer, boolean) method should be used as these are more efficient.

Overrides:

toString in class Object

Returns

the encoded URL as a string

getParameterMap

Map<String,String[]> getParameterMap()

Returns a Map of the parameters currently set on this portlet URL via the setParameter or setParameters methods.

The values in the returned Map are from type String array (String[]).

If no parameters exist this method returns an empty Map.

Returns

Map containing parameter names as keys and parameter values as map values, or an empty Map if no parameters exist. The keys in the parameter map are of type String. The values in the parameter map are of type String array (String[]).

Since:

2.0

write

void write(Writer out)
           throws IOException

Writes the portlet URL to the output stream using the provided writer.

Note that the URL written to the output stream may not be a valid URL, as it may be rewritten by the portal/portlet-container before returning the markup to the client.

The URL written to the output stream is always XML escaped. For writing non-escaped URLs use write(java.io.Writer, boolean).

Parameters

out - the writer to write the portlet URL to

Throws

IOException - if an I/O error occured while writing the URL

Since:

2.0

write

void write(Writer out,
           boolean escapeXML)
           throws IOException

Writes the portlet URL to the output stream using the provided writer. If the parameter escapeXML is set to true the URL will be escaped to be valid XML characters, i.e. &lt, &gt, &amp, &#039, &#034 will get converted into their corresponding character entity codes (&lt to &&lt, &gt to &&gt, &amp to &&amp, &#039 to &&#039, &#034 to &&#034). If escapeXML is set to false no escaping will be done.

Note that the URL written to the output stream may not be a valid URL, as it may be rewritten by the portal/portlet-container before returning the markup to the client.

Parameters

out - the writer to write the portlet URL to

escapeXML - denotes if the URL should be XML escaped before written to the output stream or not

Throws

IOException - if an I/O error occurred while writing the URL

addProperty

void addProperty(String key,
                 String value)

Adds a String property to an existing key on the URL.

This method allows URL properties to have multiple values.

Properties can be used by portlets to provide vendor specific information to the URL.

Parameters

key - the key of the property

value - the value of the property

Throws

IllegalArgumentException - if key is null.

Since:

2.0

setProperty

void setProperty(String key,
                 String value)

Sets a String property on the URL.

Properties can be used by portlets to provide vendor specific information to the URL.

This method resets all properties previously added with the same key.

Parameters

key - the key of the property

value - the value of the property

Throws

IllegalArgumentException - if key is null.
