Class BeanPropertyMap

java.lang.Object
  com.fasterxml.jackson.databind.deser.impl.BeanPropertyMap

All Implemented Interfaces:

Iterable<SettableBeanProperty>

public final class BeanPropertyMap
extends Object
implements Iterable<SettableBeanProperty>

Helper class used for storing mapping from property name to SettableBeanProperty instances.

Note that this class is used instead of generic HashMap for bit of performance gain (and some memory savings): although default implementation is very good for generic use cases, it can be streamlined a bit for specific use case we have. Even relatively small improvements matter since this is directly on the critical path during deserialization, as it is done for each and every POJO property deserialized.

void	remove(SettableBeanProperty property) Specialized method for removing specified existing entry.
BeanPropertyMap	renameAll(NameTransformer transformer) Factory method for constructing a map where all entries use given prefix
void	replace(SettableBeanProperty property) Specialized method that can be used to replace an existing entry (note: entry MUST exist; otherwise exception is thrown) with specified replacement.
int	size()

Method Detail

withProperty

public BeanPropertyMap withProperty(SettableBeanProperty newProperty)

Fluent copy method that creates a new instance that is a copy of this instance except for one additional property that is passed as the argument. Note that method does not modify this instance but constructs and returns a new one.
