public abstract class EnumerationAttribute<V extends Enum<V> & EnumerationValue>
extends TypedAttribute<V>

Base class for all generated classes which realize an Attribute with an "enumeration type", like

 
  <!ATTLIST e
      f (a | b | ..c:d | e-_0123) #IMPLIED
   >
  

For each such attribute a new enumeration type will be defined, as static inner class of the attribute's class. This class is called "Value". It will be used as the type parameter for the generated Attribute's class. The methods are type-safe, as a TdomAttributeSyntaxException is only thrown when an attribute is absent (null) and not #IMPLIED.

According to [XML 1.0], grammar rule [59], an Enumeration type consists of a set of "Nmtoken". These are words made of letters, digits and few punctation characters. But the items of the enumeration must be valid Java identifiers. They are of the form
"Value_" + makeJavaName(s)
while that method replaces "." ":" and "-" by underscores.
The generated enumeration type will get a EnumerationValue.getStringValue() method to re-translate any value into its original external representation.
The String arguments of the following methods but use this original wording of the enumeration values.

Constructor Details

EnumerationAttribute

protected EnumerationAttribute()

EnumerationAttribute

protected EnumerationAttribute(@Opt
 @Opt String value)
                        throws TdomAttributeSyntaxException

Throws:

TdomAttributeSyntaxException

EnumerationAttribute

protected EnumerationAttribute(@Opt
 V value)
                        throws TdomAttributeSyntaxException

Throws:

TdomAttributeSyntaxException

EnumerationAttribute

protected EnumerationAttribute(TypedAttribute.SafeValues flag,
 @Opt
 V value)

This variant may only be invoked by generated code if attribute is #IMPLIED and not #FIXED. In this case no TdomAttributeSyntaxException can be thrown, because all Enumeration values and null are permitted.

Method Details

checkValue

protected void checkValue(@Opt
 V value)

Check routine for the validity of the attributes' intended value. Is a call-back, implemented by the sub-classes. Is called only here, by two constructors and the TypedAttribute.setValue(V) method. The value null means "absent" for #IMPLIED attributes and passes the test.

Specified by:

checkValue in class TypedAttribute<V extends Enum<V> & EnumerationValue>

Parameters:

value - the value to test; maybe null.

setValue

public void setValue(String value)
              throws TdomAttributeSyntaxException

Throws:

TdomAttributeSyntaxException

setValue

public void setValue(@Opt
 V newValue,
 TypedAttribute.SafeValues flag)

Internal use only. Is called by the generated code iff attribute is #IMPLIED, because then never a TdomAttributeSyntaxException will be thrown.

getTypeString

public String getTypeString()

The definition text for the "type" of the attribute in the original DTD.

Specified by:

getTypeString in class TypedAttribute<V extends Enum<V> & EnumerationValue>

getValueClass

protected abstract Class<V> getValueClass()

Will be overridden in the generated code by a method which returns the dedicated value class.

Returns:

the Class object for the values of this attribute.

getValueMap

protected abstract Map<String,? extends V> getValueMap()

Returns a map from the external representations as appearing in the DTD to the enumeration items of the value's type. Will be overridden by the generated code.

getStringValue

public final String getStringValue(V v)

Returns the textual representation of a possible attribute value (not null), as it would be contained literally in a possible XML text representation. Since the textual representation of a String is the string itself, this method is relevant for enumeration types only (Later: also for "entity" types, but these are not yet supported.)

Specified by:

getStringValue in class TypedAttribute<V extends Enum<V> & EnumerationValue>

Returns:

(never null) the textual representation of this attribute value, as it would be contained literally in a possible XML text representation.

encode

public final void encode(EncodingOutputStream out,
 TypedExtension ext)
                  throws IOException

Description copied from class: TypedNode

Abstract fall-back method which MUST be overridden and always throws an Exception.

Specified by:

encode in class TypedNode<TypedExtension>

Throws:

IOException

decode

final void decode(DecodingInputStream in,
 TypedExtension ext)
           throws IOException,
TdomAttributeSyntaxException

Description copied from class: TypedAttribute

DOCUMENT ME

Specified by:

decode in class TypedAttribute<V extends Enum<V> & EnumerationValue>

Throws:

find

protected <V extends Enum<V>> V find(Map<String,? extends V> items,
 Attributes attrs,
 NamespaceName name)
                              throws TdomAttributeSyntaxException

Throws:

TdomAttributeSyntaxException
