Method Detail

getMode

PojoPropertyAccessorMode<? extends PojoPropertyAccessor> getMode()

This method gets the mode of this accessor.

Returns:

the access mode.

getAccessibleObject

AccessibleObject getAccessibleObject()

This method gets the accessible object used to access (read/write) this property.

Returns:

the method to read this property or null if this property is NOT readable.

PropertyDescriptor, Method, Constructor, Field

getModifiers

int getModifiers()

This method gets the modifiers of the accessible object.

Returns:

the modifiers of the field or method.

See Also:

Modifier, Field.getModifiers(), Method.getModifiers()

getReturnType

GenericType<?> getReturnType()

This method gets the GenericType of the object returned when this accessor is invoked.

Returns:

the return type.

See Also:

Method.getGenericReturnType(), Field.getGenericType()

getReturnClass

Class<?> getReturnClass()

This method gets the Class of the object returned when this accessor is invoked.
is a convenience method for getReturnType(). getUpperBound()

Returns:

the return class.

See Also:

Method.getReturnType(), Field.getType()

getPropertyType

GenericType<?> getPropertyType()

This method gets the GenericType of this property.
For a getter this will be the return-type while a setter typically has void as return-type and this method will return the type of its argument. For mapped or indexed getters/setters this method will return the item type.

Returns:

the GenericType reflecting the property.

See Also:

getPropertyClass(), PropertyDescriptor

getPropertyClass

Class<?> getPropertyClass()

This method gets the type as Class. It is a convenience method for getPropertyType(). getUpperBound() if the mode is for reading and getPropertyType(). getLowerBound() otherwise.

Returns:

the Class reflecting the property.

getDeclaringClass

Class<?> getDeclaringClass()

This method gets the class reflecting the type that declared this accessor. It may be the pojo-class this accessor was created from but it may also be a super-class where the field or method of this accessor is inherited from and is NOT overridden.
E.g. the read-accessor for the property "class" will have the declaring-class Object.

Returns:

the class reflecting the type that declared this accessor.
