Method Detail

invokeGetterMethod

public static java.lang.Object invokeGetterMethod(java.lang.Object object,
                                                  java.lang.String propertyName)

Tries to invoke a getter method for the given propertyName on the provided object.

Note that the getter method should meet the following requirements:

• method name must follow the standard getter naming convention
• method must be declared as public
• method cannot accept any arguments

Parameters:

object - Object on which to invoke the getter method.

propertyName - Name of the property containing the requested value.

Returns:

Getter method invocation result.

resolvePropertyPath

public static java.lang.Object resolvePropertyPath(java.lang.Object object,
                                                   java.lang.String propertyPath)

Tries to resolve the given dot-separated propertyPath on the provided object by traversing its properties.

This is a convenient way of accessing nested properties of a root object programatically.

Note that the method is null-friendly - it won't throw a NullPointerException during the object traversal (a null value is returned instead).

Parameters:

object - Object on which to resolve the property path.

propertyPath - Dot-separated logical path to the target property.

Returns:

Property resolution result.
