DefaultObjectBuilder

public DefaultObjectBuilder(Class<T> prototypeClass,
                            ReflectionCache reflectionCache)

Creates a new instance that will build instances of prototypeClass.

Method Detail

addPropertyResolver

public ObjectBuilder<T> addPropertyResolver(String propertyName,
                                            ValueResolver<? extends Object> resolver)

Adds a property which value is to be obtained from a ValueResolver

Parameters:

propertyName - the name of the property in which the value is to be assigned

resolver - a ValueResolver used to provide the actual value

Returns:

this builder

Throws:

{@link - java.lang.IllegalArgumentException} if method or resolver are null

addPropertyResolver

public ObjectBuilder<T> addPropertyResolver(Field field,
                                            ValueResolver<? extends Object> resolver)

Adds a property which value is to be obtained from a ValueResolver

Parameters:

field - the property in which the value is to be assigned

resolver - a ValueResolver used to provide the actual value

Returns:

this builder

Throws:

{@link - java.lang.IllegalArgumentException} if method or resolver are null

isDynamic

public boolean isDynamic()

Whether any of the registered ValueResolvers are dynamic

Specified by:

isDynamic in interface ObjectBuilder<T>

Returns:

true if at least one resolver is dynamic. false otherwise

build

public T build(ValueResolvingContext context)
        throws org.mule.runtime.api.exception.MuleException

Description copied from interface: ObjectBuilder
