Method Detail

expand

public String expand(Parameters parameters)

Expands the template to produce a URI as defined by the URI Template specifications.

Specified by:

expand in interface Expandable

Parameters:

parameters - The list of variables and their values for substitution.

Returns:

The expanded URI fragment

expand

public static String expand(String template,
            Parameters parameters)

Method provided for convenience.

It returns the same as:

 return new URITemplate(template).expand(variables);
 

Parameters:

template - The URI template.

parameters - The parameter values to use for substitution.

Returns:

The corresponding expanded URI.

digest

public static List<Token> digest(String template)
                          throws URITemplateSyntaxException

Returns the list of tokens corresponding to the specified URI template.

Parameters:

template - The URI template to digest.

Returns:

The corresponding list of URL tokens.

Throws:

URITemplateSyntaxException - If the string cannot be parsed.

digest

public static List<Token> digest(String template,
                 TokenFactory factory)
                          throws URITemplateSyntaxException

Returns the list of tokens corresponding to the specified URI template.

Parameters:

template - The URI template to digest.

Returns:

The corresponding list of URL tokens.

Throws:

URITemplateSyntaxException - If the string cannot be parsed.
