Method Detail

isGetter

public static boolean isGetter(Method method)

getGetterShorthandName

public static String getGetterShorthandName(Method method)

getSetterShorthandName

public static String getSetterShorthandName(Method method)

isSetter

public static boolean isSetter(Method method,
                               boolean allowBuilderPattern)

isSetter

getProperties

public static boolean getProperties(Object target,
                                    Map<String,Object> properties,
                                    String optionPrefix)

Will inspect the target for properties.

Notice a property must have both a getter/setter method to be included.

Parameters:

target - the target bean

properties - the map to fill in found properties

optionPrefix - an optional prefix to append the property key

Returns:

true if any properties was found, false otherwise.

                           throws Exception

This method supports two modes to set a property: 1. Setting a property that has already been resolved, this is the case when context and refName are NULL and value is non-NULL. 2. Setting a property that has not yet been resolved, the property will be resolved based on the suitable methods found matching the property name on the target bean. For this mode to be triggered the parameters context and refName must NOT be NULL, and value MUST be NULL.

Throws:

Exception
