Enum Constant Summary

Enum Constants

Enum Constant and Description
ENABLE_STREAMING Enables streaming by setting the document's total number of bytes in the header to 0.
WRITE_BIGDECIMALS_AS_DECIMAL128 Forces BigDecimals to be written as Decimal128s.
WRITE_BIGDECIMALS_AS_STRINGS Forces BigDecimals to be written as Strings.

Enum Constant Detail

ENABLE_STREAMING

public static final BsonGenerator.Feature ENABLE_STREAMING

Enables streaming by setting the document's total number of bytes in the header to 0. This allows the generator to flush the output buffer from time to time. Otherwise the generator would have to buffer the whole file to be able to calculate the total number of bytes.

ATTENTION: By enabling this feature, the BSON document generated by this class will not be compatible to the specification! However, if you know what you are doing and if you know that the document will be read by a parser that ignores the total number of bytes anyway (like BsonParser or org.bson.BSONDecoder from the MongoDB Java Driver do) then this feature will be very useful.

This feature is disabled by default.

WRITE_BIGDECIMALS_AS_STRINGS

public static final BsonGenerator.Feature WRITE_BIGDECIMALS_AS_STRINGS

Forces BigDecimals to be written as Strings. The BSON format supports IEEE 754 doubles only (64 bits). You may want to enable this feature if you want to serialize numbers that require more bits or a higher accuracy.

This feature is disabled by default.

WRITE_BIGDECIMALS_AS_DECIMAL128

public static final BsonGenerator.Feature WRITE_BIGDECIMALS_AS_DECIMAL128

Forces BigDecimals to be written as Decimal128s. (since BSON specification 1.1).

This feature is disabled by default.

Method Detail

values

public static BsonGenerator.Feature[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (BsonGenerator.Feature c : BsonGenerator.Feature.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static BsonGenerator.Feature valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getMask

public int getMask()

Returns:

the bit mask that identifies this feature
