Constructor Detail

DefinitionContext

public DefinitionContext(IContainer contain)

Constructor. Uses the containing context to establish the hierarchy for resolving namespaces and class mappings.

Parameters:

contain - containing binding definition component

Method Detail

addNamespace

public void addNamespace(NamespaceDefinition def)

Add namespace to set defined at this level. If the new namespace conflicts with an existing namespace at this level (in terms of default usage or prefix) this throws an exception.

Parameters:

def - namespace definition to be added (duplicates ignored)

addImpliedNamespace

public void addImpliedNamespace(NamespaceDefinition def)

Add namespace declaration to set defined at this level. This method treats all namespaces as though they were declared with default="none". If the new namespace prefix conflicts with an existing namespace this throws an exception.

Parameters:

def - namespace definition to be added (duplicates ignored)

addMapping

public void addMapping(IMapping def)
                throws JiBXException

Add class mapping to set defined at this level. If the new mapping conflicts with an existing one at this level it throws an exception.

Parameters:

def - mapping definition to be added

Throws:

JiBXException - on mapping definition conflict

addNamedStructure

public void addNamedStructure(String name,
                              IComponent comp)
                       throws JiBXException

Add named structure component to set defined at this level. If the name conflicts with an existing one at this level it throws an exception.

Parameters:

name - component name to be set

comp - named component

Throws:

JiBXException - on mapping definition conflict

getDefaultURI

public String getDefaultURI(boolean attr)

Get the default namespace URI for a contained name. Elements and attributes are treated separately, since namespace handling differs between the two.

Parameters:

attr - flag for attribute name

Returns:

default namespace URI, or null if none

getDefaultIndex

public int getDefaultIndex(boolean attr)

Get the default namespace index for a contained name. Elements and attributes are treated separately, since namespace handling differs between the two.

Parameters:

attr - flag for attribute name

Returns:

default namespace index

getNamespaceIndex

public int getNamespaceIndex(String uri,
                             boolean attr)
                      throws JiBXException

Get namespace index for a given URI. Finds the prefix for a URI in a name contained by this level, throwing an exception if the URI is not found or does not have a prefix.

Parameters:

uri - namespace URI to be found

attr - flag for attribute name

Returns:

namespace index for URI

Throws:

JiBXException - if URI not defined or not usable

getMappingAtLevel

public IMapping getMappingAtLevel(String name)

Get mapping definition for class if defined at this level.

Parameters:

name - fully qualified class name

Returns:

mapping definition for class, or null if not defined

getClassMapping

public IMapping getClassMapping(String name)

Get mapping definition for class. Finds the mapping for a fully qualified class name, throwing an exception if no mapping is defined. This can only be used during the linkage phase.

Parameters:

name - fully qualified class name

Returns:

mapping definition for class, or null if not defined

getNamedStructure

public IComponent getNamedStructure(String name)
                             throws JiBXException

Get nested structure by name. Finds the nested structure with the given name, throwing an exception if no component with that name is defined.

Parameters:

name - component name to be found

Returns:

component with given name

Throws:

JiBXException - if name not defined

getMappings

public ArrayList getMappings()

Get mapping definitions at level.

Returns:

mapping definitions, null if none defined at level

getSpecificConversion

public StringConversion getSpecificConversion(String name)

Get specific conversion definition for type. Finds with an exact match on the class name, checking the containing definitions if a conversion is not found at this level.

Parameters:

name - fully qualified class name to be converted

Returns:

conversion definition for class, or null if not found

getConversion

public StringConversion getConversion(ClassFile clas)

Get conversion definition for class. Finds the conversion based on a fully qualified class name. If a specific conversion for the actual class is not found (either in this or a containing level) this returns the generic object conversion.

Parameters:

clas - information for target conversion class

Returns:

conversion definition for class

getNamedConversion

public StringConversion getNamedConversion(QName name)

Get named conversion definition. Finds the conversion with the supplied name, checking the containing definitions if the conversion is not found at this level.

Parameters:

name - conversion name to be found

Returns:

conversion definition for class

addConversion

public void addConversion(QName name,
                          StringConversion conv)
                   throws JiBXException

Add named conversion. Checks for duplicate conversions defined within a level with the same name.

Parameters:

name - format name for this conversion

conv - conversion definition for class

Throws:

JiBXException - if duplicate conversion definition

setConversion

public void setConversion(StringConversion conv)
                   throws JiBXException

Set specific conversion definition for type. Sets the conversion based on a type signature, checking for duplicate conversions defined within a level.

Parameters:

conv - conversion definition for class

Throws:

JiBXException - if duplicate conversion definition

setNamedConversion

public void setNamedConversion(QName name,
                               StringConversion conv)
                        throws JiBXException

Sets a named conversion definition.

Parameters:

name - format name for this conversion

conv - conversion definition for class

Throws:

JiBXException - if duplicate conversion definition

setDefaultConversion

public void setDefaultConversion(QName name,
                                 StringConversion conv)
                          throws JiBXException

Sets a conversion definition by both type and name. Both the type and name are checked for duplicate conversions defined within a level.

Parameters:

name - format name for this conversion

conv - conversion definition for class

Throws:

JiBXException - if duplicate conversion definition

hasNamespace

public boolean hasNamespace()

Check if one or more namespaces are defined in this context.

true if namespaces are defined, false if not

getNamespaces

public ArrayList getNamespaces()

Get the namespaces defined in this context

Returns:

namespace definitions (may be null if none)

genLoadNamespaces

public void genLoadNamespaces(MethodBuilder mb)

Generate code for loading namespace index and URI arrays. The code creates the arrays and leaves the references on the stack.

Parameters:

mb - method builder for generated code

generateCode

public void generateCode(boolean verbose,
                         boolean force)
                  throws JiBXException

Generate code. Executes code generation for each top-level mapping defined in this binding, which in turn propagates the code generation all the way down.

Parameters:

verbose - flag for verbose output

force - create marshaller/unmarshaller even for abstract non-base mappings flag

Throws:

JiBXException - if error in transformation

linkMappings

public void linkMappings()
                  throws JiBXException

Links extension mappings to their base mappings. This must be done before the more general linking step in order to determine which abstract mappings are standalone and which are extended by other mappings

Throws:

JiBXException - if error in linking

setLinkages

public void setLinkages()
                 throws JiBXException

Set linkages between binding components. This is called after all the basic information has been set up. All linkage to higher level components should be done by this method, in order to prevent problems due to the order of definitions between components. For the definition context this calls the same method on all mappings defined in this context.

Throws:

JiBXException - if error in configuration

print

public void print(int depth)
