All Implemented Interfaces:

JavaElement, JavaField, JavaMember

public class ReflectionJavaField
extends BaseReflectionJavaField

A reflection based JavaField implementation used at runtime. The implementation takes java.lang.reflect.Field instances to get Java related metadata about fields.

Constructor Detail

ReflectionJavaField

public ReflectionJavaField(java.lang.reflect.Field field,
                   JavaType declaringClass)

Constructor for fields w/o JDO metadata.

Parameters:

field - the reflection field representation.

declaringClass - the JavaType of the class that declares the field.

ReflectionJavaField

public ReflectionJavaField(java.lang.String fieldName,
                   JavaType type,
                   JavaType declaringClass)

Constructor for fields having JDO metadata.

Parameters:

fieldName - the name of the field.

type - the field type.

declaringClass - the JavaType of the class that declares the field.

Method Detail

getType

public JavaType getType()

Returns the JavaType representation of the field type.

Specified by:

getType in interface JavaMember

Overrides:

getType in class BaseReflectionJavaField

Returns:

field type

getJavaTypeForClass

public JavaType getJavaTypeForClass(java.lang.Class clazz)

Returns a JavaType instance for the specified Class object. This method provides a hook such that ReflectionJavaField subclasses can implement their own mapping of Class objects to JavaType instances.
