Method Summary

Object	get(Object instance) Reads the property value.
<T extends Annotation> T	getAnnotation(Class<T> annotationClass) Searches for the specified annotation, returning the matching annotation instance.
Class	getBeanType() Returns the type of bean to which this property belongs.
ClassPropertyAdapter	getClassAdapter() Returns the ClassPropertyAdapter that provides access to other properties defined by the same class.
Class	getDeclaringClass() The class in which the property (or public field) is defined.
Field	getField() Returns the field if the property is a public field or null if the property is accessed via the read method.
String	getName() Returns the name of the property (or public field).
Method	getReadMethod() Returns the method used to read the property, or null if the property is not readable (or is a public field).
Class	getType() Returns the type of the property.
Method	getWriteMethod() Returns the method used to update the property, or null if the property is not writeable (or a public field).
boolean	isCastRequired() Returns true if the return type of the read method is not the same as the property type.
boolean	isField() Returns true if the property is actually a public field (possibly, a public static field).
boolean	isRead() Returns true if the property is readable (i.e., has a getter method or is a public field).

Method Detail

getName

public String getName()

Description copied from interface: PropertyAdapter

Returns the name of the property (or public field).

Specified by:

getName in interface PropertyAdapter

getReadMethod

public Method getReadMethod()

Description copied from interface: PropertyAdapter

Returns the method used to read the property, or null if the property is not readable (or is a public field).

Specified by:

getReadMethod in interface PropertyAdapter

getType

public Class getType()

Description copied from interface: PropertyAdapter

Returns the type of the property.

Specified by:

getType in interface PropertyAdapter

getWriteMethod

public Method getWriteMethod()

Description copied from interface: PropertyAdapter

Returns the method used to update the property, or null if the property is not writeable (or a public field).

Specified by:

getWriteMethod in interface PropertyAdapter

isRead

public boolean isRead()

Description copied from interface: PropertyAdapter

Returns true if the property is readable (i.e., has a getter method or is a public field).

Specified by:

isRead in interface PropertyAdapter

isUpdate

public boolean isUpdate()

Description copied from interface: PropertyAdapter

Returns true if the property is writeable (i.e., has a setter method or is a non-final field).

Specified by:

isUpdate in interface PropertyAdapter

get

public Object get(Object instance)

Description copied from interface: PropertyAdapter

Reads the property value.

Specified by:

get in interface PropertyAdapter

Parameters:

instance - to read from

set

public void set(Object instance,
                Object value)

Description copied from interface: PropertyAdapter

Updates the property value. The provided value must not be null if the property type is primitive, and must otherwise be of the proper type.

Specified by:

set in interface PropertyAdapter

getAnnotation

public <T extends Annotation> T getAnnotation(Class<T> annotationClass)

Description copied from interface: AnnotationProvider

Searches for the specified annotation, returning the matching annotation instance.

Specified by:

getAnnotation in interface AnnotationProvider

Parameters:

annotationClass - used to select the annotation to return

Returns:

the annotation, or null if not found

isCastRequired

public boolean isCastRequired()

Description copied from interface: PropertyAdapter

Returns true if the return type of the read method is not the same as the property type. This can occur when the property has been defined using generics, in which case, the method's type may be Object when the property type is something more specific. This method is primarily used when generating runtime code related to the property.

Specified by:

isCastRequired in interface PropertyAdapter

getClassAdapter

public ClassPropertyAdapter getClassAdapter()

Returns the ClassPropertyAdapter that provides access to other properties defined by the same class.

Specified by:

getClassAdapter in interface PropertyAdapter

getBeanType

public Class getBeanType()

Description copied from interface: PropertyAdapter

Returns the type of bean to which this property belongs. This is the same as ClassPropertyAdapter.getBeanType().

Specified by:

getBeanType in interface PropertyAdapter

isField

public boolean isField()

Description copied from interface: PropertyAdapter

Returns true if the property is actually a public field (possibly, a public static field).

Specified by:

isField in interface PropertyAdapter

getField

public Field getField()

Description copied from interface: PropertyAdapter

Returns the field if the property is a public field or null if the property is accessed via the read method.

Specified by:

getField in interface PropertyAdapter

getDeclaringClass

public Class getDeclaringClass()

Description copied from interface: PropertyAdapter

The class in which the property (or public field) is defined.

Specified by:
