DocumentProperties (GigaSpaces 16.4.0 API)

java.lang.Object
- com.gigaspaces.document.DocumentProperties

All Implemented Interfaces:

Externalizable, Serializable, Map<String,Object>
```
public class DocumentProperties
extends Object
implements Map<String,Object>, Externalizable
```
An implementation of Map optimized for usage with SpaceDocument. DocumentProperties contains the following enhancements: 1. Usability: Fluent-styled setProperty method to enable fluent coding. 2. Serialization performance: Externalizable implementation with special optimization for properties names. 3. Memory footprint: Open-addressing algorithm is used to conserve memory usage.

Since:

8.0

    Specified by:
    
    readExternal in interface Externalizable

    IOException
    
    ClassNotFoundException
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - equals
```
public boolean equals(Object obj)
```
    Compares the specified object with this map for equality. Returns true if the given object is also a map and the two Maps represent the same mappings. More formally, two maps t1 and t2 represent the same mappings if t1.entrySet().equals(t2.entrySet()). This ensures that the equals method works properly across different implementations of the Map interface.
    
    Specified by:
    
    equals in interface Map<String,Object>
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - object to be compared for equality with this map.
    
    Returns:
    
    true if the specified object is equal to this map.
  - hashCode
```
public int hashCode()
```
    Returns the hash code value for this map. The hash code of a map is defined to be the sum of the hashCodes of each entry in the map's entrySet view. This ensures that t1.equals(t2) implies that t1.hashCode()==t2.hashCode() for any two maps t1 and t2, as required by the general contract of Object.hashCode.
    
    Specified by:
    
    hashCode in interface Map<String,Object>
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    the hash code value for this map.

    Object.hashCode(), Object.equals(Object), equals(Object)
