Default implementation of a Class property.

Data is stored in the associated PropertyData object as a Class object. This is immutable so can be directly returned.

Method Detail

getPropertyType

public java.lang.Class getPropertyType()

Get the type of the property. A method String getFoo() has a property type of String.class.

Specified by:

getPropertyType in interface Property

Returns:

the property type

getInternal

protected java.lang.Class getInternal()

Get the property as a Class

Returns:

the stored value

setInternal

protected void setInternal(java.lang.Class newValue)

Set the property value as a Class

Parameters:

newValue - the value to store

toObject

public java.lang.Object toObject()

Description copied from interface: Property

Get the property's value as an object. The object type will be appropriate for the type of property. The object will either be immutable or a clone of the real object.

This method has strong semantics such that where a and b are properties of the same type, it must be true that:
b.set( a.toObject() ); a.equals(b);
In other words, the object contains all the data necessary to recreate the property's value.

Specified by:

toObject in interface Property

Specified by:

toObject in class AbstractProperty

Returns:

an Object representing the property's value

See Also:

Property#toObject()

toClass

public java.lang.Class toClass()

Description copied from interface: ClassProperty

Get the property's value as a Class.

Specified by:

toClass in interface ClassProperty

Returns:

the property value as a Class

See Also:

ClassProperty.toClass()

get

public java.lang.Class get()

Description copied from interface: ClassProperty

Get the property's value as a Class.

Specified by:

get in interface ClassProperty

Returns:

the property value as a Class

See Also:

ClassProperty.get()

convertObjectToClass

protected java.lang.Class convertObjectToClass(java.lang.Object object)

Convert an Object to a Class, throwing an exception if unable to convert.

Parameters:

object - the value to convert

Returns:

the converted boolean

set

public void set(java.lang.Object propertyValue)

Description copied from interface: Property

Set the property's value as an object. The object type should be appropriate for the type of property. If necessary, the object will be cloned before it is stored internally. Implementations will recognise as many types of object passed in as possible. Null should always be accepted, primitive types will be reset back to zero/false.

If a String is passed in, it can be parsed in various ways. If the results of toDataString() are passed in, it must reconstitute the original value.

Specified by:

set in interface Property

Specified by:

set in class AbstractProperty

Parameters:

propertyValue - an Object to set the property's value to

See Also:

Property#set(Object)

newInstance

public java.lang.Object newInstance()

Description copied from interface: ClassProperty

Create a new instance of the class.

Specified by:

newInstance in interface ClassProperty

Returns:

a new instance of the class

See Also:

ClassProperty.newInstance()
