Class UriBuilder

    java.lang.Object
      javax.ws.rs.core.UriBuilder

Direct Known Subclasses:
  UriBuilderImpl

    public abstract class UriBuilder

extends java.lang.Object

URI template aware utility class for building URIs from their components. See `Path.value()` for an explanation of URI templates.

Builder methods perform contextual encoding of characters not permitted in the corresponding URI component following the rules of the application/x-www-form-urlencoded media type for query parameters and RFC 3986 for all other components. Note that only characters not permitted in a particular component are subject to encoding so, e.g., a path supplied to one of the `path` methods may contain matrix parameters or multiple path segments since the separators are legal characters and will not be encoded. Percent encoded values are also recognized where allowed and will not be double encoded.

URI templates are allowed in most components of a URI but their value is restricted to a particular component. E.g.

> `UriBuilder.fromPath("{arg1}").build("foo#bar");`

would result in encoding of the '#' such that the resulting URI is "foo%23bar". To create a URI "foo#bar" use

> `UriBuilder.fromPath("{arg1}").fragment("{arg2}").build("foo", "bar")`

instead. URI template names and delimiters are never encoded but their values are encoded when a URI is built. Template parameter regular expressions are ignored when building a URI, i.e. no validation is performed.

  Append path to the existing path. When constructing the final path, a '/' separator will be inserted between the existing path and the supplied path if necessary. Existing '/' characters are preserved thus a single value can represent multiple URI path segments.

  Parameters:
    `resource` - a resource whose `Path` value will be used to obtain the path to append.
  Returns:
    the updated UriBuilder

                             throws java.lang.IllegalArgumentException

  Append the path from a Path-annotated method to the existing path. When constructing the final path, a '/' separator will be inserted between the existing path and the supplied path if necessary. This method is a convenience shortcut to `path(Method)`, it can only be used in cases where there is a single method with the specified name that is annotated with `Path`.

  Parameters:
    `resource` - the resource containing the method
    `method` - the name of the method whose `Path` value will be used to obtain the path to append
  Returns:
    the updated UriBuilder
  Throws:

  Parameters:
    `method` - a method whose `Path` value will be used to obtain the path to append to the existing path
  Returns:
    the updated UriBuilder
  Throws:
    `java.lang.IllegalArgumentException` - if method is null or is not annotated with a `Path`

### segment

    public abstract UriBuilder segment(java.lang.String... segments)
                                throws java.lang.IllegalArgumentException

  Append path segments to the existing path. When constructing the final path, a '/' separator will be inserted between the existing path and the first path segment if necessary and each supplied segment will also be separated by '/'. Existing '/' characters are encoded thus a single value can only represent a single URI path segment.

  Parameters:
    `segments` - the path segment values, each may contain URI template parameters
  Returns:
    the updated UriBuilder
  Throws:
    `java.lang.IllegalArgumentException` - if segments or any element of segments is null

### replaceMatrix

    public abstract UriBuilder replaceMatrix(java.lang.String matrix)
                                      throws java.lang.IllegalArgumentException

  Set the matrix parameters of the current final segment of the current URI path. This method will overwrite any existing matrix parameters on the current final segment of the current URI path. Note that the matrix parameters are tied to a particular path segment; subsequent addition of path segments will not affect their position in the URI path.

  Parameters:
    `matrix` - the matrix parameters, may contain URI template parameters. A null value will remove all matrix parameters of the current final segment of the current URI path.
  Returns:
    the updated UriBuilder

  Append a matrix parameter to the existing set of matrix parameters of the current final segment of the URI path. If multiple values are supplied the parameter will be added once per value. Note that the matrix parameters are tied to a particular path segment; subsequent addition of path segments will not affect their position in the URI path.

  Parameters:
    `name` - the matrix parameter name, may contain URI template parameters
    `values` - the matrix parameter value(s), each object will be converted to a `String` using its `toString()` method. Stringified values may contain URI template parameters.

  Replace the existing value(s) of a matrix parameter on the current final segment of the URI path. If multiple values are supplied the parameter will be added once per value.
