Properties for Null Property Handling
Property Notes
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.

When set to false, null-valued concept properties are output to XML.

See Enabling Null Property Values to Appear When Serializing Concepts to XML .

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).
