Class TupleJSONUtil.SetTupleFromJSON
java.lang.Object
com.streambase.sb.TupleJSONUtil.SetTupleFromJSON
- Enclosing class:
TupleJSONUtil
The Builder class which handles the setting of tuples from JSON Data.
This has several parameters which can be specified using the respective builder methods.
These builder methods are:
Two static instances are provided:
withParseStyle(com.streambase.sb.ParseStyle)
whether to throw an exception when fields are missing from tuple's schema (ParseStyle.STRICT
) or not (ParseStyle.LOOSE
)
withTimestampStyle(com.streambase.sb.Timestamp.Type)
timestampStyle Whether the numeric values in a timestamp field will be converted to an Timestamp.Type.INTERVAL
or a Timestamp.Type.TIMESTAMP
withTimestampFormat(java.lang.String)
the string representation of the timestamp format to use when converting
withEmptyStringValue(java.lang.String)
the string specifying what an empty/null json field should evaluate to
Two static instances are provided:
STRICT
and LOOSE
,
which set all defaults except for the parseStyle, which instead corresponds to the instance name.
STRICT
can be used as a plain default instance with no modifications.-
