isInstance back to summary

isInstance	back to summary
public static boolean isInstance(Class<?> clazz, String type) Checks to see if the specified class is an instance of or assignable from the specified type. The class `clazz`, all its superclasses, interfaces and those superinterfaces are tested for a match against the type name `type`. This is similar to `instanceof` or `Class#isAssignableFrom` except that the target type will not be resolved into a Class object, which provides some security and memory benefits. Parameters clazz:Class<?> The class to test for a match. type:String The name of the type that `clazz` must be. Returns:boolean `true` if the `clazz` tested is an instance of the specified `type`, `false` otherwise.

public static boolean isInstance(Class<?> clazz, String type)

Checks to see if the specified class is an instance of or assignable from the specified type. The class clazz, all its superclasses, interfaces and those superinterfaces are tested for a match against the type name type. This is similar to instanceof or Class#isAssignableFrom except that the target type will not be resolved into a Class object, which provides some security and memory benefits.

Parameters

clazz:Class<?>: The class to test for a match.
type:String: The name of the type that clazz must be.

Returns:boolean

true if the clazz tested is an instance of the specified type, false otherwise.

replaceProperties	back to summary
public static String replaceProperties(String value, Hashtable<Object, Object> staticProp, IntrospectionUtils.PropertySource[] dynamicProp, ClassLoader classLoader) Replaces ${NAME} in the value with the value of the property 'NAME'. Replaces ${NAME:DEFAULT} with the value of the property 'NAME:DEFAULT', if the property 'NAME:DEFAULT' is not set, the expression is replaced with the value of the property 'NAME', if the property 'NAME' is not set, the expression is replaced with 'DEFAULT'. If the property is not set and there is no default the value will be returned unmodified. Parameters value:String The value staticProp:Hashtable<Object, Object> Replacement properties dynamicProp:IntrospectionUtils.PropertySource[] Replacement properties classLoader:ClassLoader Class loader associated with the code requesting the property Returns:String the replacement value

public static String replaceProperties(String value, Hashtable<Object, Object> staticProp, IntrospectionUtils.PropertySource[] dynamicProp, ClassLoader classLoader)

Replaces ${NAME} in the value with the value of the property 'NAME'. Replaces ${NAME:DEFAULT} with the value of the property 'NAME:DEFAULT', if the property 'NAME:DEFAULT' is not set, the expression is replaced with the value of the property 'NAME', if the property 'NAME' is not set, the expression is replaced with 'DEFAULT'. If the property is not set and there is no default the value will be returned unmodified.

Parameters

value:String: The value
