## org.springframework.beans
Class PropertyValue

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

All Implemented Interfaces:
  Serializable, BeanMetadataElement, AttributeAccessor

    public class PropertyValue

extends BeanMetadataAttributeAccessor
implements 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 Summary
`PropertyValue(PropertyValue original)` Copy constructor.
`PropertyValue(PropertyValue original, Object newValue)` Constructor that exposes a new value for an original value holder.
`PropertyValue(String name, Object value)` Create a new PropertyValue instance.

Method Summary
`boolean` | `equals(Object other)`
`Object` | `getConvertedValue()` Return the converted value of the constructor argument, after processed type conversion.
`String` | `getName()` Return the name of the property.
`PropertyValue` | `getOriginalPropertyValue()` Return the original PropertyValue instance for this value holder.
`Object` | `getValue()` Return the value of the property.
`int` | `hashCode()`
`boolean` | `isConverted()` Return whether this holder contains a converted value already (`true`), or whether the value still needs to be converted (`false`).
`boolean` | `isOptional()`
`void` | `setConvertedValue(Object value)` Set the converted value of the constructor argument, after processed type conversion.
`void` | `setOptional(boolean optional)`
`String` | `toString()`

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`)

### PropertyValue

    public PropertyValue(PropertyValue original,
                         Object newValue)

  Constructor that exposes a new value for an original value holder. The original holder will be exposed as source of the new holder.

  Parameters:
    `original` - the PropertyValue to link to (never `null`)
    `newValue` - the new value to apply

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.

### getOriginalPropertyValue

    public PropertyValue getOriginalPropertyValue()

  Return the original PropertyValue instance for this value holder.

  Returns:
    the original PropertyValue (either a source of this value holder or this value holder itself).

### setOptional

    public void setOptional(boolean optional)

### isOptional

    public boolean isOptional()

### 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`
