net.sf.morph.transform.converters
Class BooleanToTextConverter

java.lang.Object
  net.sf.morph.transform.transformers.BaseTransformer
      net.sf.morph.transform.converters.BooleanToTextConverter

All Implemented Interfaces:

net.sf.composite.Component, Converter, DecoratedConverter, DecoratedTransformer, ExplicitTransformer, ImpreciseTransformer, Transformer

public class BooleanToTextConverter
extends BaseTransformer
implements DecoratedConverter, ImpreciseTransformer

Converts boolean values to text values. Subclasses can build in support for locale-sensitive translations of true and false to text values by overriding getTrueString(Locale) and getFalseString(Locale).

Method Detail

convertImpl

protected java.lang.Object convertImpl(java.lang.Class destinationClass,
                                       java.lang.Object source,
                                       java.util.Locale locale)
                                throws java.lang.Exception

The implementation of the convert method, which may omit the invalid argument checks already performed by this base class. By default, this method creates a new instance of the destinationClass and copies information from the source to the destination. This implementation should be fine as-is for Copiers, but Converters will need to implement this method since they will not be implementing the copy method.

Overrides:

convertImpl in class BaseTransformer

locale - the locale in which the conversion should take place. for converters that are not locale-aware, the local argument can simply be ignored

Throws:

java.lang.Exception

getSourceClassesImpl

protected java.lang.Class[] getSourceClassesImpl()
                                          throws java.lang.Exception

Transformer.getSourceClasses() implementation template method.

Specified by:

getSourceClassesImpl in class BaseTransformer

Returns:

Class[]

Throws:

java.lang.Exception

getDestinationClassesImpl

protected java.lang.Class[] getDestinationClassesImpl()
                                               throws java.lang.Exception

Transformer.getDestinationClasses() implementation template method.

Specified by:

getDestinationClassesImpl in class BaseTransformer

Returns:

Class[]

Throws:

java.lang.Exception

getTrueString

public java.lang.String getTrueString(java.util.Locale locale)

Get the string representation of true.

Parameters:

locale -

Returns:

String

getFalseString

public java.lang.String getFalseString(java.util.Locale locale)

Get the string representation of false.

Parameters:

locale -

Returns:

String

isImpreciseTransformationImpl

protected boolean isImpreciseTransformationImpl(java.lang.Class destinationClass,
                                                java.lang.Class sourceClass)

Implementation of isImpreciseTransformation

Overrides:

isImpreciseTransformationImpl in class BaseTransformer

Returns:

boolean

isWrappingRuntimeExceptions

protected boolean isWrappingRuntimeExceptions()

Indicates whether runtime exceptions should be wrapped as TransformationExceptions. By default, this method returns true.

Simple transformers in Morph that operate on JDK types like Numbers and Strings will usually set this value to true so that they throw TransformationExceptions if problems occur. More complex transformers that operate on graphs of objects are encouraged to set this value to false so that runtime exceptions are not wrapped. This way, problems accessing data will be expressed by the native API of a user's domain objects and avoid the need to catch Morph-specific exceptions (assuming the use of runtime exceptions in said domain objects).

Overrides:

isWrappingRuntimeExceptions in class BaseTransformer

Returns:

true

getTextConverter

public Converter getTextConverter()

Get the text converter used by this BaseToPrettyTextConverter.

Returns:

Converter

setTextConverter

public void setTextConverter(Converter textConverter)

Set the text converter used by this BaseToPrettyTextConverter.

Parameters:

textConverter -
