Class BeanMapEntry

java.lang.Object

org.apache.juneau.BeanMapEntry

All Implemented Interfaces:

Map.Entry<String,Object>

public class BeanMapEntry
extends Object
implements Map.Entry<String,Object>

Represents a single entry in a bean map.

This class can be used to get and set property values on a bean, or to get metadata on a property.

Example:

// Construct a new bean Person p = new Person(); // Wrap it in a bean map BeanMap<Person> b = BeanContext.DEFAULT.forBean(p); // Get a reference to the birthDate property BeanMapEntry birthDate = b.getProperty("birthDate"); // Set the property value birthDate.setValue(new Date(1, 2, 3, 4, 5, 6)); // Or if the DateSwap.DEFAULT_ISO8601DT is registered with the bean context, set a transformed value birthDate.setValue("'1901-03-03T04:05:06-5000'");

Constructor Detail

BeanMapEntry

protected BeanMapEntry(BeanMap<?> beanMap,
                       BeanPropertyMeta property,
                       String pName)

Constructor.

Parameters:

beanMap - The bean map that this entry belongs to.

property - The bean property.

pName - The bean property name.

Method Detail

getKey

public String getKey()

Specified by:

getKey in interface Map.Entry<String,Object>

getValue

public Object getValue()

Returns the value of this property.

If there is a PojoSwap associated with this bean property or bean property type class, then this method will return the transformed value. For example, if the bean property type class is a Date and the bean property has the TemporalDateSwap.IsoInstant swap associated with it through the @Swap(value) annotation, this method will return a String containing an ISO8601 date-time string value.

Specified by:

getValue in interface Map.Entry<String,Object>

setValue

public Object setValue(Object value)

Sets the value of this property.

If the property is an array of type X, then the value can be a Collection<X> or X[] or Object[].

If the property is a bean type X, then the value can either be an X or a Map.

If there is a PojoSwap associated with this bean property or bean property type class, then you must pass in a transformed value. For example, if the bean property type class is a Date and the bean property has the TemporalDateSwap.IsoInstant swap associated with it through the @Swap(value) annotation, the value being passed in must be a String containing an ISO8601 date-time string value.

Specified by:

setValue in interface Map.Entry<String,Object>

Returns:

The set value after it's been converted.

getBeanMap

public BeanMap<?> getBeanMap()

Returns the bean map that contains this property.

Returns:

The bean map that contains this property.

getMeta

public BeanPropertyMeta getMeta()

Returns the metadata about this bean property.

Returns:

Metadata about this bean property.

toString

public String toString()

Overrides:

toString in class Object
