Class UriBuilder

  • public abstract class UriBuilder
extends 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 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.

      • replaceMatrix

        public abstract UriBuilder replaceMatrix​(String matrix)
        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.

      • buildFromMap

        public abstract URI buildFromMap​(Map<String,​?> values)
        Build a URI. Any URI template parameters will be replaced by the value in the supplied map. Values are converted to String using their toString() method and are then encoded to match the rules of the URI component to which they pertain. All '%' characters in the stringified values will be encoded. The state of the builder is unaffected; this method may be called multiple times on the same builder instance.

        NOTE: By default all '/' characters in the stringified values will be encoded in path templates, i.e. the result is identical to invoking buildFromMap(valueMap, true). To override this behavior use buildFromMap(valueMap, false) instead.

        Parameters:
        values - a map of URI template parameter names and values.
        Returns:
        the URI built from the UriBuilder.
        Throws:
        IllegalArgumentException - if there are any URI template parameters without a supplied value, or if a template parameter value is null.
        UriBuilderException - if a URI cannot be constructed based on the current state of the builder.

      • buildFromMap

        public abstract URI buildFromMap​(Map<String,​?> values,

                                 UriBuilderException
        Build a URI. Any URI template parameters will be replaced by the value in the supplied map. Values are converted to String using their toString() method and are then encoded to match the rules of the URI component to which they pertain. All '%' characters in the stringified values will be encoded. The state of the builder is unaffected; this method may be called multiple times on the same builder instance.

        The encodeSlashInPath parameter may be used to override the default encoding of '/' characters in the stringified template values in cases when the template is part of the URI path component when using the buildFromMap(java.util.Map) method. If the encodeSlashInPath parameter is set to true (default), the slash ('/') characters in parameter values will be encoded if the template is placed in the URI path component. If set to false the default encoding behavior is overridden an slash characters in template values will not be encoded when used to substitute path templates.

        Parameters:

                                        UriBuilderException
        Build a URI. Any URI template parameters will be replaced by the value in the supplied map. Values are converted to String using their toString() method and are then encoded to match the rules of the URI component to which they pertain. All % characters in the stringified values that are not followed by two hexadecimal numbers will be encoded. The state of the builder is unaffected; this method may be called multiple times on the same builder instance.
        Parameters:
        values - a map of URI template parameter names and values.
        Returns:
        the URI built from the UriBuilder.
        Throws:
        IllegalArgumentException - if there are any URI template parameters without a supplied value, or if a template parameter value is null.
        UriBuilderException - if a URI cannot be constructed based on the current state of the builder.

                   throws IllegalArgumentException,
                          UriBuilderException
        Build a URI, using the supplied values in order to replace any URI template parameters. Values are converted to String using their toString() method and are then encoded to match the rules of the URI component to which they pertain. All '%' characters in the stringified values will be encoded. The state of the builder is unaffected; this method may be called multiple times on the same builder instance.

        All instances of the same template parameter will be replaced by the same value that corresponds to the position of the first instance of the template parameter. e.g. the template "{a}/{b}/{a}" with values {"x", "y", "z"} will result in the the URI "x/y/x", not "x/y/z".

        NOTE: By default all '/' characters in the stringified values will be encoded in path templates, i.e. the result is identical to invoking build(Object[], boolean) build(values, true)}. To override this behavior use build(values, false) instead.

        Parameters:
        values - a list of URI template parameter values.
        Returns:
        the URI built from the UriBuilder.
        Throws:
        IllegalArgumentException - if there are any URI template parameters without a supplied value, or if a value is null.
        UriBuilderException - if a URI cannot be constructed based on the current state of the builder.

                   throws IllegalArgumentException,
                          UriBuilderException
        Build a URI, using the supplied values in order to replace any URI template parameters. Values are converted to String using their toString() method and are then encoded to match the rules of the URI component to which they pertain. All '%' characters in the stringified values will be encoded. The state of the builder is unaffected; this method may be called multiple times on the same builder instance.

        The encodeSlashInPath parameter may be used to override the default encoding of '/' characters in the stringified template values in cases when the template is part of the URI path component when using the build(Object[]) method. If the encodeSlashInPath parameter is set to true (default), the slash ('/') characters in parameter values will be encoded if the template is placed in the URI path component. If set to false the default encoding behavior is overridden an slash characters in template values will not be encoded when used to substitute path templates.

        Parameters:
        values - a list of URI template parameter values.
        encodeSlashInPath - if true, the slash ('/') characters in parameter values will be encoded if the template is placed in the URI path component, otherwise the slash characters will not be encoded in path templates.
        Returns:
        the URI built from the UriBuilder.
        Throws:
        IllegalArgumentException - if there are any URI template parameters without a supplied value, or if a value is null.
