Field Details

STRICT_DESERIALIZATION

static final PropertyValue<Boolean> STRICT_DESERIALIZATION

Specifies whether strict deserialization should be used. This means that when an unknown attribute
is encountered during deserialization, an exception is thrown, instead of silently dropping the associated value.
Value type: Boolean
Default value: true
