com.pervasive.datarush.schema.TextConversionDefaults
public final class TextConversionDefaults extends Object
Describes behaviors used during conversion of token values to and from text. These settings are typically used to describe default behavior for a schema. Text types are not required to honor any of these settings. The default behavior for text type processing is:
  • Null values are indicated by an empty string ("").
  • String-valued types do not perform whitespace trimming and tread the empty string as a null value.
