Class BsonTypeClassMap

java.lang.Object

org.bson.codecs.BsonTypeClassMap

public class BsonTypeClassMap
extends java.lang.Object

A map from a BSON types to the Class to which it should be decoded. This class is useful if, for example, you want to change the default decoding of BSON DATE to something besides java.util.Date.

The default mappings are:

• DOCUMENT: org.bson.Document.class
• ARRAY: java.util.List.class
• DATE_TIME: java.util.Date.class
• BOOLEAN: java.lang.Boolean.class
• DOUBLE: java.lang.Double.class
• INT32: java.lang.Integer.class
• INT64: java.lang.Long.class
• DECIMAL128: org.bson.types.Decimal128.class
• STRING: java.lang.String.class
• BINARY: org.bson.types.Binary.class
• OBJECT_ID: org.bson.types.ObjectId.class
• REGULAR_EXPRESSION: org.bson.types.RegularExpression.class
• SYMBOL: org.bson.types.Symbol.class
• DB_POINTER: org.bson.types.DBPointer.class
• MAX_KEY: org.bson.types.MaxKey.class
• MIN_KEY: org.bson.types.MinKey.class
• JAVASCRIPT: org.bson.types.Code.class
• JAVASCRIPT_WITH_SCOPE: org.bson.types.CodeWithScope.class
• TIMESTAMP: org.bson.types.BSONTimestamp.class
• UNDEFINED: org.bson.types.Undefined.class

Constructor Detail

BsonTypeClassMap

public BsonTypeClassMap(java.util.Map<BsonType,java.lang.Class<?>> replacementsForDefaults)

Construct an instance with the default mapping, but replacing the default mapping with any values contained in the given map. This allows a caller to easily replace a single or a few mappings, while leaving the rest at their default values.

Parameters:

replacementsForDefaults - the replacement mappings

BsonTypeClassMap

public BsonTypeClassMap()

Construct an instance with the default mappings.

Method Detail

keys

java.util.Set<BsonType> keys()

get

public java.lang.Class<?> get(BsonType bsonType)

Gets the Class that is mapped to the given BSON type.

Parameters:

bsonType - the BSON type

Returns:

the Class that is mapped to the BSON type

addDefaults

private void addDefaults()

equals

public boolean equals(java.lang.Object o)

Overrides:
