## com.fasterxml.jackson.databind.deser.impl
Class BeanPropertyMap

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

All Implemented Interfaces:
  Serializable, Iterable<SettableBeanProperty>

    public final class BeanPropertyMap

extends Object
implements Iterable<SettableBeanProperty>, Serializable

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.

Constructor Summary
`BeanPropertyMap(Collection<SettableBeanProperty> properties)`

Method Summary
`BeanPropertyMap` | `assignIndexes()`
`SettableBeanProperty` | `find(String key)`
`SettableBeanProperty[]` | `getPropertiesInInsertionOrder()` Method that will re-create initial insertion-ordering of properties contained in this map.
`Iterator<SettableBeanProperty>` | `iterator()` Accessor for traversing over all contained properties.
`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()`
`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.

Constructor Detail

### BeanPropertyMap

    public BeanPropertyMap(Collection<SettableBeanProperty> properties)

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.

  Since:
    2.0

### renameAll

    public BeanPropertyMap renameAll(NameTransformer transformer)

  Factory method for constructing a map where all entries use given prefix

### assignIndexes

    public BeanPropertyMap assignIndexes()

### iterator

    public Iterator<SettableBeanProperty> iterator()

  Accessor for traversing over all contained properties.

  Specified by:
    `iterator` in interface `Iterable<SettableBeanProperty>`

### getPropertiesInInsertionOrder

    public SettableBeanProperty[] getPropertiesInInsertionOrder()

  Method that will re-create initial insertion-ordering of properties contained in this map. Note that if properties have been removed, array may contain nulls; otherwise it should be consecutive.

  Since:
    2.1

### size

    public int size()

### find

    public SettableBeanProperty find(String key)

### replace

    public 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.

### remove

    public void remove(SettableBeanProperty property)

  Specialized method for removing specified existing entry. NOTE: entry MUST exist, otherwise an exception is thrown.
