org.springframework.beans
Class PropertyValue

java.lang.Object
  org.springframework.core.AttributeAccessorSupport
      org.springframework.beans.PropertyValue

All Implemented Interfaces:

Serializable, BeanMetadataElement, AttributeAccessor

---

public class PropertyValue
extends AttributeAccessorSupport
implements BeanMetadataElement, Serializable

Object to hold information and value for an individual bean property. Using an object here, rather than just storing all properties in a map keyed by property name, allows for more flexibility, and the ability to handle indexed properties etc in an optimized way.

Note that the value doesn't need to be the final required type: A BeanWrapper implementation should handle any necessary conversion, as this object doesn't know anything about the objects it will be applied to.

Constructor Detail

PropertyValue

public PropertyValue(String name,
                     Object value)

Create a new PropertyValue instance.

Parameters:

name - the name of the property (never null)

value - the value of the property (possibly before type conversion)

---

PropertyValue

public PropertyValue(PropertyValue original)

Copy constructor.

Parameters:

original - the PropertyValue to copy (never null)

Method Detail

getName

public String getName()

Return the name of the property.

---

getValue

public Object getValue()

Return the value of the property.

Note that type conversion will not have occurred here. It is the responsibility of the BeanWrapper implementation to perform type conversion.

---

setSource

public void setSource(Object source)

Set the configuration source Object for this metadata element.

The exact type of the object will depend on the configuration mechanism used.

---

getSource

public Object getSource()

Description copied from interface: BeanMetadataElement

Return the configuration source Object for this metadata element (may be null).

Specified by:

getSource in interface BeanMetadataElement

---

isConverted

public boolean isConverted()

Return whether this holder contains a converted value already (true), or whether the value still needs to be converted (false).

---

setConvertedValue

public void setConvertedValue(Object value)

Set the converted value of the constructor argument, after processed type conversion.

---

getConvertedValue

public Object getConvertedValue()

Return the converted value of the constructor argument, after processed type conversion.

---

equals

public boolean equals(Object other)

Overrides:

equals in class AttributeAccessorSupport

---

hashCode

public int hashCode()

Overrides:

hashCode in class AttributeAccessorSupport

---

toString

public String toString()

Overrides:

toString in class Object
