 org.springframework.binding.mapping.MappingBuilder
| MappingBuilder | | public class MappingBuilder (Code) | | A stateful builder that builds
Mapping objects. Designed for
convenience to build mappings in a clear, readable manner.
Example usage:
MappingBuilder mapping = new MappingBuilder();
Mapping result = mapping.source("foo").target("bar").from(String.class).to(Long.class).value();
Calling the
MappingBuilder.value() result method clears out this builder's state so
it can be reused to build another mapping.

| Constructor Summary | |
| public | MappingBuilder(ExpressionParser expressionParser)
Creates a mapping builder that uses the expression parser to parse
attribute mapping expressions. |
| MappingBuilder | | public MappingBuilder(ExpressionParser expressionParser)(Code) | | Creates a mapping builder that uses the expression parser to parse
attribute mapping expressions.
Parameters:
expressionParser - the expression parser |
| from | | public MappingBuilder from(Class sourceType)(Code) | | Sets the expected type of the object returned by evaluating the source
expression. Used in conjunction with
MappingBuilder.to(Class) to perform a type
conversion during the mapping process.
Parameters:
sourceType - the source type this, to support call-chaining |
| required | | public MappingBuilder required()(Code) | | Marks the mapping to be built a "required" mapping.
this, to support call-chaining |
| reset | | public void reset()(Code) | | Reset this mapping builder.
|
| setConversionService | | public void setConversionService(ConversionService conversionService)(Code) | | Sets the conversion service that will convert the object returned by
evaluating the source expression to the
MappingBuilder.to(Class) type if
necessary.
Parameters:
conversionService - the conversion service |
| source | | public MappingBuilder source(String expressionString)(Code) | | Sets the source expression of the mapping built by this builder.
Parameters:
expressionString - the expression string this, to support call-chaining |
| target | | public MappingBuilder target(String expressionString)(Code) | | Sets the target property expression of the mapping built by this builder.
Parameters:
expressionString - the expression string this, to support call-chaining |
| targetCollection | | public MappingBuilder targetCollection(String expressionString)(Code) | | Sets the target collection of the mapping built by this builder.
Parameters:
expressionString - the expression string, resolving a collection this, to support call-chaining |
| to | | public MappingBuilder to(Class targetType)(Code) | | Sets the target type of the property writeable by the target expression.
Parameters:
targetType - the target type this, to support call-chaining |
| value | | public Mapping value()(Code) | | The logical GoF builder getResult method, returning a fully constructed
Mapping from the configured pieces. Once called, the state of this
builder is nulled out to support building a new mapping object again.
