Properties for Null Property Handling
Property | Note
--- | ---
Properties Set in BE_HOME/studio/eclipse/configuration/studio.tra
    tibco.be.schema.nil.attribs
| Setting this property to true causes the `xsd:nillable` attribute (`"xsd:nillable=true"`) to be set on all elements in the TIBCO BusinessEvents concept XSD. See Enabling Use of the Nillable Attribute Possible values are true and false. Default is false.
    tibco.be.schema.exclude.null.props
| When this property is set to true, null-valued concept properties are not output when the concept is serialized to XML or JSON. When set to false, null-valued concept properties are output to XML or JSON. See Enabling Null Property Values to Appear When Serializing Concepts to XML or JSON . Possible values are true and false. Default is true.
    tibco.be.schema.treat.null.values
| Setting this property to true causes TIBCO BusinessEvents to use special numeric values that indicate null for numeric datatypes. The special numeric values are set using the properties listed next. Possible values are true and false. Default is false.
Properties Set in CDD at the cluster level
    tibco.be.property.int.null.value
    tibco.be.property.long.null.value
    tibco.be.property.double.null.value
    tibco.be.property.boolean.null.value
| These properties define a special value that indicates null. Use a value that will not be confused with an actual numeric value. These properties are used only if `tibco.be.schema.treat.null.values` is set to true. Default values for each numeric datatype are the following Java constants: `int: Integer.MIN_VALUE` `long: Long.MIN_VALUE` `double: Double.MIN_VALUE`
    boolean: Boolean.FALSE
For Integer and Long these constants represent the most negative value. For Double the constant represents smallest positive nonzero value (4.9e-324).
