Set the value of the field to the given value.
Set the value of the field to the given value. Note: Because setting a field can fail (return non-Full), this method will return defaultValue if the field could not be set.
A list of functions that transform the value before it is set.
A list of functions that transform the value before it is set. The transformations are also applied before the value is used in a query. Typical applications of this are trimming and/or toLowerCase-ing strings
Set the value of the field from anything.
Set the value of the field from anything. Implementations of this method should accept at least the following (pattern => valueBox)
Note that setFromAny should _always_ call setBox, even if the conversion fails. This is so that validation properly notes the error.
The method genericSetFromAny implements this guideline.

Decode the JValue and set the field to the decoded value.

Set the value of the field using some kind of type-specific conversion from a String.
Set the value of the field using some kind of type-specific conversion from a String. By convention, if the field is optional_?, then the empty string should be treated as no-value (Empty). Note that setFromString should _always_ call setBox, even if the conversion fails. This is so that validation properly notes the error.
Full(convertedValue) if the conversion succeeds (the field value will be set by side-effect) Empty or Failure if the conversion does not succeed

A field that maps to a decimal value. Decimal precision and rounding are controlled via the context parameter. The default value is zero.
Note:
Using MathContext.UNLIMITED, whether explicitly or implicitly, means that no precision or scaling will be used for the SQL field definition; the default scale for DECIMAL is zero per the SQL standard, but the precision for DECIMAL is vendor-specific. For example, PostgreSQL uses maximum precision if it's not specified, but SQL Server uses a default precision of 18.
