Constructor Details

XMLContext

public XMLContext()
Creates an instance of XMLContext with an internal XML context.

Method Details

addClass

public void addClass(Class clazz)
            throws ResolverException
Loads the class descriptor for the class instance specified. The use of this method is useful when no mapping is used, as happens when the domain classes has been generated using the XML code generator (in which case instead of a mapping file class descriptor files will be generated).
Parameters:
clazz - the class for which the associated descriptor should be loaded.
Throws:
ResolverException - in case that resolving the Class fails fatally

addClasses

public void addClasses(Class[] clazzes)
            throws ResolverException
Loads the class descriptor for the class instance specified. The use of this method is useful when no mapping is used, as happens when the domain classes hase been generated using the XML code generator (in which case instead of a mapping file class descriptor files will be generated).
Parameters:
clazzes - the classes for which the associated descriptor should be loaded.
Throws:
ResolverException - in case that resolving the Class fails fatally

addMapping

public void addMapping(Mapping mapping)
            throws MappingException
Instructs Castor to load class descriptors from the mapping given.
Parameters:
mapping - Castor XML mapping (file), from which the required class descriptors will be derived.
Throws:
MappingException - If the Mapping cannot be loaded and analyzed successfully.

addPackage

public void addPackage(String packageName)
            throws ResolverException
Loads class descriptors from the package specified. The use of this method is useful when no mapping is used, as happens when the domain classes hase been generated using the XML code generator (in which case instead of a mapping file class descriptor files will be generated).

Please note that this functionality will work only if you provide the .castor.cdr file with your generated classes (as generated by the XML code generator).

Parameters:
packageName - The package name for the (descriptor) classes
Throws:
ResolverException - If there's a problem loading class descriptors for the given package.

addPackages

public void addPackages(String[] packageNames)
            throws ResolverException
Loads class descriptors from the packages specified. The use of this method is useful when no mapping is used, as happens when the domain classes hase been generated using the XML code generator (in which case instead of a mapping file class descriptor files will be generated).

Please note that this functionality will work only if you provide the .castor.cdr files with your generated classes (as generated by the XML code generator).

Parameters:
packageNames - The package names for the (descriptor) classes
Throws:
ResolverException - If there's a problem loading class descriptors for the given package.

createChangeLog2XML

public ChangeLog2XML createChangeLog2XML()
To create a new ChangeLog2XML instance.
Returns:
the ChangeLog2XML instance ready to use

createMapping

public Mapping createMapping()
Creates an instance of a Castor XML specific Mapping instance.
Returns:
a Castor XML specific Mapping instance.

createMappingTool

public MappingTool createMappingTool()
To create a MappingTool instance.
Returns:
the MappingTool instance ready to use

createMarshaller

public Marshaller createMarshaller()
Creates a new Marshaller instance to be used for marshalling.
Returns:
A new Marshaller instance.

createUnmarshaller

public Unmarshaller createUnmarshaller()
Creates a new Unmarshaller instance to be used for unmarshalling.
Returns:
A new Unmarshaller instance, preconfigured with a XMLClassDescriptorResolver instance with the class descriptors cached as loaded above.

getInternalContext

public InternalContext getInternalContext()

Deprecated.

To get the InternalContext as used when instantiating other classes. Mind that this method is only used in tests and should NOT be used in production code!
Returns:
the InternalContext used

getProperty

public Object getProperty(String propertyName)
To get the value of a specific property.
Parameters:
propertyName - name of the Property
Returns:
the value (Object) of the property

setProperty

public void setProperty(String propertyName,
                        Object value)
To set properties for marshalling and unmarshalling behavior.
Parameters:
propertyName - name of the property to set
value - the value to set to

setProperty

public void setProperty(String propertyName,
                        boolean value)
To set properties for marshalling and unmarshalling behavior.
Parameters:
propertyName - name of the property to set
value - the value to set to
