Method Detail

getReadType

public static Type getReadType(javax.xml.stream.XMLStreamReader xsr,
                               AegisContext context,
                               Type baseType)

getReadTypeStandalone

public static Type getReadTypeStandalone(javax.xml.stream.XMLStreamReader xsr,
                                         AegisContext context,
                                         Type baseType)

getReadType cannot just look up the xsi:type in the mapping. This function must be called instead at the root where there is no initial mapping to start from, as from a part or an element of some containing item.

Parameters:

xsr -

context -

Returns:

getWriteType

public static Type getWriteType(AegisContext globalContext,
                                java.lang.Object value,
                                Type type)

getWriteTypeStandalone

public static Type getWriteTypeStandalone(AegisContext globalContext,
                                          java.lang.Object value,
                                          Type type)

getWriteTypeStandalone

public static Type getWriteTypeStandalone(AegisContext globalContext,
                                          java.lang.Object value,
                                          java.lang.reflect.Type reflectType)

Allow writing of collections when the type of the collection object is known via an Type object.

Parameters:

globalContext - the context

value - the object to write.

reflectType - the type to use in writing the object.

Returns:

setAttributeAttributes

public static void setAttributeAttributes(javax.xml.namespace.QName name,
                                          Type type,
                                          org.apache.ws.commons.schema.XmlSchema root)

getTypeClass

public static java.lang.Class<?> getTypeClass(java.lang.reflect.Type type,
                                              boolean throwForNonClass)

Utility function to cast a Type to a Class. This throws an unchecked exception if the Type is not a Class. The idea here is that these Type references should have been checked for reasonableness before the point of calls to this function.

Parameters:

type - Reflection type.

throwForNonClass - whether to throw (true) or return null (false) if the Type is not a class.

Returns:

the Class

getSingleTypeParameter

public static java.lang.reflect.Type getSingleTypeParameter(java.lang.reflect.Type type)

Insist that a Type is a parameterized type of one parameter. This is used to decompose Holders, for example.

Parameters:

type - the type

Returns:

the parameter, or null if the type is not what we want.

getSingleTypeParameter

public static java.lang.reflect.Type getSingleTypeParameter(java.lang.reflect.Type type,
                                                            int index)

Insist that a Type is a parameterized type of one parameter. This is used to decompose Holders, for example.

Parameters:

type - the type

index - which parameter

Returns:

the parameter, or null if the type is not what we want.

getTypeRelatedClass

public static java.lang.Class<?> getTypeRelatedClass(java.lang.reflect.Type type)

If a Type is a class, return it as a class. If it is a ParameterizedType, return the raw type as a class. Otherwise return null.

Parameters:

type -

Returns:
