cn.taketoday.expression.spel.support.DataBindingPropertyAccessor

所有已实现的接口:

PropertyAccessor

public final class DataBindingPropertyAccessor
extends ReflectivePropertyAccessor

A PropertyAccessor variant for data binding purposes, using reflection to access properties for reading and possibly writing.

A property can be referenced through a public getter method (when being read) or a public setter method (when being written), and also as a public field.

This accessor is explicitly designed for user-declared properties and does not resolve technical properties on java.lang.Object or java.lang.Class. For unrestricted resolution, choose ReflectivePropertyAccessor instead.

DataBindingPropertyAccessor

private DataBindingPropertyAccessor(boolean allowWrite)

Create a new property accessor for reading and possibly also writing.

参数:

allowWrite - whether to also allow for write operations

isCandidateForProperty

protected boolean isCandidateForProperty(Method method,
 Class<?> targetClass)

从类复制的说明: ReflectivePropertyAccessor

Determine whether the given Method is a candidate for property access on an instance of the given target class.

The default implementation considers any method as a candidate, even for non-user-declared properties on the Object base class.

覆盖:

isCandidateForProperty 在类中 ReflectivePropertyAccessor

参数:

method - the Method to evaluate

targetClass - the concrete target class that is being introspected

forReadOnlyAccess

public static DataBindingPropertyAccessor forReadOnlyAccess()

Create a new data-binding property accessor for read-only operations.

forReadWriteAccess

public static DataBindingPropertyAccessor forReadWriteAccess()

Create a new data-binding property accessor for read-write operations.
