+--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));
}
....
}

public ParameterlessDatatypeBuilder(Datatype baseType)
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.
