Method Summary

Modifier and Type	Method and Description
java.util.Set<java.lang.String>	getAllProperties()
java.lang.String	getClassName()
java.lang.Class<?>	getClazz()
java.util.Set<java.lang.String>	getOwnProperties()
java.lang.String[]	getProperties() Deprecated. since 1.2; use getOwnProperties() instead
java.lang.Object	getValue(java.lang.Object object, java.lang.String attribute) Gets the attribute of the object by invoking either object.get<attribute>(), object.<attribute>() or object.is<attribute>() (trying in that order).
java.lang.Object	newInstance() Creates a new instance of the underlying class.
void	removeObject(java.lang.Object object) Removes all associations from the object by calling it's removeYou() method.

Reflector	setClassName(java.lang.String className)
Reflector	setClazz(java.lang.Class<?> clazz)
Reflector	setUseEMF() Signifies to this reflector that the underlying class uses EMF.
java.lang.Object	setValue(java.lang.Object object, java.lang.String attribute, java.lang.Object value) Sets the attribute of the object to the new value by invoking a fitting set<attribute>(...) or with<attribute>(...) method or get<attribute>.add(...) for EMF to-many associations.
java.lang.Object	setValue(java.lang.Object object, java.lang.String attribute, java.lang.Object value, java.lang.String type) Deprecated. since 1.2; use setValue(Object, String, Object) instead

Method Detail

getClazz

public java.lang.Class<?> getClazz()

setClazz

public Reflector setClazz(java.lang.Class<?> clazz)

getClassName

public java.lang.String getClassName()

setClassName

public Reflector setClassName(java.lang.String className)

setUseEMF

public Reflector setUseEMF()

Signifies to this reflector that the underlying class uses EMF. As such, semantics of the various methods provided by this class change in accordance to the EMF conventions.

Returns:

this instance, to allow method chaining

getProperties

@Deprecated
public java.lang.String[] getProperties()

Deprecated. since 1.2; use getOwnProperties() instead

Equivalent to getOwnProperties().toArray(new String[0]).

Returns:

a sorted array of names of properties the underlying clazz has.

getOwnProperties

public java.util.Set<java.lang.String> getOwnProperties()

Returns:

a sorted set of names of properties of the underlying class.

Since:

1.2

getAllProperties

public java.util.Set<java.lang.String> getAllProperties()

Returns:

a sorted set of names of properties the underlying class, it's super class and it's interfaces provide.

Since:

1.2

newInstance

public java.lang.Object newInstance()

Creates a new instance of the underlying class. If this reflector uses EMF, the EMF create method is called. Otherwise, the default (no-arg) constructor of the underlying class is invoked. Any exception raised by either operation is ignored; in this case null is returned

Returns:

a new instance of the underlying class, or null if that fails

getValue

public java.lang.Object getValue(java.lang.Object object,
                                 java.lang.String attribute)

Gets the attribute of the object by invoking either object.get<attribute>(), object.<attribute>() or object.is<attribute>() (trying in that order).

Parameters:

object - the receiver object

attribute - the attribute name

Returns:

the return value of the getter, or null if no getter was found

setValue

@Deprecated
public java.lang.Object setValue(java.lang.Object object,
                                             java.lang.String attribute,
                                             java.lang.Object value,
                                             java.lang.String type)

Deprecated. since 1.2; use setValue(Object, String, Object) instead

Sets the attribute of the object to the new value by invoking a fitting set<attribute>(...) or with<attribute>(...) method or get<attribute>.add(...) for EMF to-many associations.

Parameters:

object - the object to modify

attribute - the attribute name

value - the new value

type - unused

Returns:

the return value of the setter, or true if successful, or null if unsuccessful

setValue

public java.lang.Object setValue(java.lang.Object object,
                                 java.lang.String attribute,
                                 java.lang.Object value)

Sets the attribute of the object to the new value by invoking a fitting set<attribute>(...) or with<attribute>(...) method or get<attribute>.add(...) for EMF to-many associations.

Parameters:

object - the object to modify

attribute - the attribute name

value - the new value

Returns:

the return value of the setter, or true if successful, or null if unsuccessful

Since:

1.2

removeValue

public void removeValue(java.lang.Object object,
                        java.lang.String attribute,
                        java.lang.Object target)

Removes the link from object to target by invoking a fitting set<attribute>(null) or without<attribute>(target) method.

Parameters:

object - the source object

attribute - the link name

target - the target that shall no longer be attached to object

Since:

1.4

removeObject

public void removeObject(java.lang.Object object)

Removes all associations from the object by calling it's removeYou() method. If that method is not available, no action is taken. In particular, no exception is thrown in that case.

Parameters:

object - the object to remove
