## org.relaxng.datatype.helpers
Class ParameterlessDatatypeBuilder

    java.lang.Object
      org.relaxng.datatype.helpers.ParameterlessDatatypeBuilder

All Implemented Interfaces:
  DatatypeBuilder

    public final class ParameterlessDatatypeBuilder

extends java.lang.Object
implements DatatypeBuilder

Dummy implementation of `DatatypeBuilder`. This implementation can be used for Datatypes which have no parameters. Any attempt to add parameters will be rejected.

Typical usage would be:

     class MyDatatypeLibrary implements DatatypeLibrary {
         ....
         DatatypeBuilder createDatatypeBuilder( String typeName ) {
             return new ParameterleessDatatypeBuilder(createDatatype(typeName));
         }
         ....
     }

Method Detail

### addParameter

    public void addParameter(java.lang.String name,
                             java.lang.String strValue,
                             ValidationContext context)
                      throws DatatypeException

  Description copied from interface: `DatatypeBuilder`
  Adds a new parameter.

  Specified by:
    `addParameter` in interface `DatatypeBuilder`
  Parameters:
    `name` - The name of the parameter to be added.
    `strValue` - The raw value of the parameter. Caller may not normalize this value because any white space is potentially significant.
    `context` - The context information which can be used by the callee to acquire additional information. This context object is valid only during this method call. The callee may not keep a reference to this object.
  Throws:
    `DatatypeException` - When the given parameter is inappropriate for some reason. The callee is responsible to recover from this error. That is, the object should behave as if no such error was occured.

### createDatatype

    public Datatype createDatatype()
                            throws DatatypeException

  Description copied from interface: `DatatypeBuilder`
  Derives a new Datatype from a Datatype by parameters that were already set through the addParameter method.

  Specified by:
    `createDatatype` in interface `DatatypeBuilder`
  Throws:
    `DatatypeException` - DatatypeException must be thrown if the derivation is somehow invalid. For example, a required parameter is missing, etc. The exception should contain a diagnosis message if possible.
