Interface XMLResource.ElementHandler

All Known Implementing Classes:

ElementHandlerImpl

Enclosing interface:

XMLResource

public static interface XMLResource.ElementHandler

An interface for an element handle that is used to deduce an appropriate feature when serializing a value of a specific type. The getRoot method is used to determine an appropriate feature to serialize a value of the given type. The getSubstitutionGroup method is used to determine a feature related by substitution group affiliation to the given feature for serializing a value of the given type.

Since:

2.4

Method Summary

EStructuralFeature	getRoot(ExtendedMetaData extendedMetaData, EClassifier eClassifier) Returns an appropriate feature for serializing a value of the give type.
EStructuralFeature	getSubstitutionGroup(ExtendedMetaData extendedMetaData, EStructuralFeature eStructuralFeature, EClassifier eClassifier) Returns an feature, related by substitution group affiliation to the given feature, for serializing a value of the give type.

Method Detail

getRoot

EStructuralFeature getRoot(ExtendedMetaData extendedMetaData,
                           EClassifier eClassifier)

Returns an appropriate feature for serializing a value of the give type.

Parameters:

extendedMetaData - the extended meta data in which to look up type information.

eClassifier - the type of value to serialize.

Returns:

an appropriate feature for serializing a value of the give type or null.

getSubstitutionGroup

EStructuralFeature getSubstitutionGroup(ExtendedMetaData extendedMetaData,
                                        EStructuralFeature eStructuralFeature,
                                        EClassifier eClassifier)

Returns an feature, related by substitution group affiliation to the given feature, for serializing a value of the give type.

Parameters:

extendedMetaData - the extended meta data in which to look up type information.

eStructuralFeature - the feature that will be used if this method returns null.

eClassifier - the type of value to serialize.

Returns:

an appropriate feature for serializing a value of the give type or null.
