Method Detail

getAttributeName

public static String getAttributeName(org.hibernate.annotations.common.reflection.XMember member,
                                      String name)

Get attribute name out of member unless overridden by name.

Parameters:

member - XMember from which to extract the name.

name - Override value which will be returned in case it is not empty.

Returns:

attribute name out of member unless overridden by name.

setAccessible

public static void setAccessible(org.hibernate.annotations.common.reflection.XMember member)

Always use this method to set accessibility regardless of the visibility.

Parameters:

member - the XMember to check

setAccessible

public static void setAccessible(AccessibleObject member)

Always use this method to set accessibility regardless of the visibility.

Parameters:

member - the AccessibleObject to change

getMemberValue

public static Object getMemberValue(Object bean,
                                    org.hibernate.annotations.common.reflection.XMember getter)

createXClassHierarchy

public static List<org.hibernate.annotations.common.reflection.XClass> createXClassHierarchy(org.hibernate.annotations.common.reflection.XClass clazz)

Creates the class hierarchy for a given XClass.

Parameters:

clazz - the class for which to create the hierarchy

Returns:

the list of classes in the hierarchy starting at java.lang.Object

containsSearchAnnotations

public static boolean containsSearchAnnotations(org.hibernate.annotations.common.reflection.XClass mappedClass)

Checks whether the specified class contains any Search-specific annotations.

This method will return true if such an annotation is detected in the class itself or in one of its superclass, either applied directly on the class, on a field, or on a method.

Parameters:

mappedClass - the XClass to check for Search annotations

Returns:

Returns true if the class contains at least one Search annotation, false otherwise

isSearchAnnotation

public static boolean isSearchAnnotation(Annotation annotation)

Checks if the annotation is a Search annotation by comparing the package of the annotation.

Parameters:

annotation - the annotation to check

Returns:

Returns true if the annotation is a Search annotation, false otherwise

createInstance

public static Object createInstance(Class<?> clazz,
                                    boolean checkForFactoryAnnotation)

Creates an instance of the specified class and returns it. If checkForFactoryAnnotation == true, the created instance is checked for a @Factory annotated method. If one exists the factory method is invoked and the return value returns as expected instances.

Parameters:

clazz - the class to instantiate

checkForFactoryAnnotation - whether to check for @Factory annotated methods

Returns:

the created instance

isFloatingPointType

public static boolean isFloatingPointType(Class<?> type)

Checks whether the specified type is a floating point type.

Parameters:

type - the type to check

Returns:

true if the specified type is an floating point type or a wrapper thereof. false otherwise.

isIntegerType

public static boolean isIntegerType(Class<?> type)

Checks whether the specified type is a integer type.

Parameters:

type - the type to check

Returns:

true if the specified type is an primitive integer type or a wrapper thereof. false otherwise.
