- Direct Known Subclasses:
ObjectStringConversion
,PrimitiveStringConversion
String conversion handling. Defines serialization handling for converting
to and from a
String
value. This uses an inheritance approach,
where each serialization definition is initialized based on the handling
set for the containing definition of the same (or parent class) type.- Author:

Constructor Details

StringConversion
Constructor. This internal form only initializes the type information.- Parameters:
type
- fully qualified name of class handled by conversion
-
StringConversion
Constructor. Initializes conversion handling based on the supplied inherited handling.- Parameters:
type
- fully qualified name of class handled by conversioninherit
- conversion information inherited by this conversion
-
StringConversion
Constructor. Initializes conversion handling based on argument values. This form is only used for constructing the default set of conversions. Because of this, it throws an unchecked exception on error.- Parameters:
dflt
- default value object (wrapped value for primitive types, otherwiseString
)ser
- fully qualified name of serialization method (null
if none)conv
- fully qualified name of whitespace conversion method (null
if none)deser
- fully qualified name of deserialization method (null
if none)type
- fully qualified name of class handled by conversion

Method Details
-
getTypeName
Get name of type handled by this conversion.- Returns:
- fully qualified class name of type handled by conversion
-
genFromText
Generate code to convertString
representation. The code generated by this method assumes that theString
value has already been pushed on the stack. It consumes this and leaves the converted value on the stack.- Parameters:
mb
- method builder- Throws:
JiBXException
- if error in configuration
-
genParseOptional
Generate code to parse and convert optional attribute or element. This abstract base class method must be implemented by every subclass. The code generated by this method assumes that the unmarshalling context and name information for the attribute or element have already been pushed on the stack. It consumes these and leaves the converted value (or converted default value, if the item itself is missing) on the stack.- Parameters:
attr
- item is an attribute (vs element) flagmb
- method builder- Throws:
JiBXException
- if error in configuration
-
genParseRequired
Generate code to parse and convert required attribute or element. This abstract base class method must be implemented by every subclass. The code generated by this method assumes that the unmarshalling context and name information for the attribute or element have already been pushed on the stack. It consumes these and leaves the converted value on the stack.- Parameters:
attr
- item is an attribute (vs element) flagmb
- method builder- Throws:
JiBXException
- if error in configuration
-
genWriteText
Generate code to writeString
value to generated document. The code generated by this method assumes that the marshalling context, the name information, and the actual value to be converted have already been pushed on the stack. It consumes these, leaving the marshalling context on the stack.- Parameters:
attr
- item is an attribute (vs element) flagmb
- method builder
-
genPopValues
Generate code to pop values from stack.- Parameters:
count
- number of values to be poppedmb
- method builder
-
genToOptionalText
protected abstract BranchWrapper genToOptionalText(String type, ContextMethodBuilder mb, int extra) throws JiBXException Generate code to check if an optional value is not equal to the default. This abstract base class method must be implemented by every subclass. The code generated by this method assumes that the actual value to be converted has already been pushed on the stack. It consumes this, leaving the converted text reference on the stack if it's not equal to the default value.- Parameters:
type
- fully qualified class name for value on stackmb
- method builderextra
- count of extra words to be popped from stack if missing- Returns:
- handle for branch taken when value is equal to the default (target must be set by caller)
- Throws:
JiBXException
- if error in configuration
-
genToText
Generate code to convert value to aString
. The code generated by this method assumes that the actual value to be converted has already been pushed on the stack. It consumes this, leaving the converted text reference on the stack.- Parameters:
type
- fully qualified class name for value on stackmb
- method builder- Throws:
JiBXException
- if error in configuration
-
genWriteOptional
public void genWriteOptional(boolean attr, String type, ContextMethodBuilder mb) throws JiBXException Generate code to convert and write optional value to generated document. The generated code first tests if the value is the same as the supplied default, and if so skips writing. The code assumes that the marshalling context, the name information, and the actual value to be converted have already been pushed on the stack. It consumes these, leaving only the marshalling context on the stack.- Parameters:
attr
- item is an attribute (vs element) flagtype
- fully qualified class name for value on stackmb
- method builder- Throws:
JiBXException
- if error in configuration
-
genWriteRequired
public void genWriteRequired(boolean attr, String type, ContextMethodBuilder mb) throws JiBXException Generate code to convert and write required value to generated document. The code generated by this method assumes that the marshalling context, the name information, and the actual value to be converted have already been pushed on the stack. It consumes these, leaving the returned marshalling context on the stack.- Parameters:
attr
- item is an attribute (vs element) flagtype
- fully qualified class name for value on stackmb
- method builder- Throws:
JiBXException
- if error in configuration
-
isPrimitive
public abstract boolean isPrimitive()Check if the type handled by this conversion is of a primitive type.- Returns:
true
if a primitive type,false
if an object type
-
setSerializer
Set serializer for conversion. This finds the named static method and sets it as the serializer to be used for this conversion. The serializer method is expected to take a single argument of either the handled type or a superclass or interface of the handled type, and to return aString
result.- Parameters:
ser
- fully qualified class and method name of serializervariant
- allow variants of the specified type- Throws:
JiBXException
- if serializer not found or not usable
-
setWhitespaceConverter
Set whitespace converter for conversion. This finds the named static method and sets it as the whitespace converter to be used for this conversion. The whitespace converter method is expected to take a single argument of typeString
, and to return the same.- Parameters:
wsconv
- fully qualified class and method name of whitespace converter- Throws:
JiBXException
- if whitespace converter not found or not usable
-
setDeserializer
Set deserializer for conversion. This finds the named static method and sets it as the deserializer to be used for this conversion. The deserializer method is expected to take a single argument of typeString
, and to return a value of the handled type or a subtype of that type.- Parameters:
deser
- fully qualified class and method name of deserializer- Throws:
JiBXException
- if deserializer not found or not usable
-
convertDefault
Convert text representation into default value object. Each subclass must implement this with the appropriate conversion handling.- Parameters:
text
- value representation to be converted- Returns:
- converted default value object
- Throws:
JiBXException
- on conversion error
-
derive
public abstract StringConversion derive(String type, String ser, String conv, String dser, String dflt) throws JiBXException Derive from existing formatting information. This abstract base class method must be implemented by every subclass. It allows constructing a new instance from an existing format of the same or an ancestor type, with the properties of the existing format copied to the new instance except where overridden by the supplied values.- Parameters:
type
- fully qualified name of class handled by conversion (null
if inherited)ser
- fully qualified name of serialization method (null
if inherited)conv
- fully qualified name of whitespace conversion method (null
if inherited)dser
- fully qualified name of deserialization method (null
if inherited)dflt
- default value text (null
if inherited)- Returns:
- new instance initialized from existing one
- Throws:
JiBXException
- if error in configuration information
