 CLASS FieldSpec

public class FieldSpec

The FieldSpec type exposes the following members.

Constructors

	Name	Description
	FieldSpec	Construct a field specification.

Properties

	Name	Description
	Decimals	A numeric value representing the number of decimals defined to this field specification.
	HyperLabel	The hyperlabel connected to this field specification.
	Length	A numeric value representing the length defined to this field specification.
	Maximum	A numeric value representing the maximum value in the range validation for this field specification.
	Minimum	A numeric value representing the minimum value in the range validation for this field specification.
	MinLength	A numeric value representing the new minimum length validation for this field specification.
	MinLengthHL	Error message when MinLength validation fails.
	Nullable	Is the field Nullable ?
	Picture	A string representing the picture clause defined to this field specification. It is used by the FieldSpec:Transform() method.
	RangeHL	Error message when Range validation fails.
	Required	Logical value indicating whether the field is required (TRUE) or not (FALSE).
	RequiredHL	Error message when Required validation fails.
	Status	After a validation request (see FieldSpec:PerformValidations() for details), this contains a HyperLabel object that describes the results of the validation or NULL_OBJECT if the validation passed.
	UsualType	A constant, representing the data type defined to this field specification:
	Validation	A code block that sets the validation rule for this field specification.
	ValidationHL	Error message when Validation fails.
	ValType	A one-character string representing the data type defined to this field specification:

Methods

	Name	Description
	_SetType
	AsString	Return the caption defined to this field specification's hyperlabel; if no caption is defined, return the name defined to the hyperlabel.
	PerformValidations	Test a specified value to see if it passes all of this field specification's validation rules.
	SetLength	Set a new length for this field specification and new hyperlabel diagnostics for the length check.
	SetMinLength	Set a new minimum length validation for this field specification and new hyperlabel diagnostics for the minimum length check.
	SetRange	Set a new range validation for this field specification and new hyperlabel diagnostics for the range check.
	SetRequired	Set a new required validation for this field specification and new hyperlabel diagnostics for the required check.
	SetType	Set a new data type for this field specification and new hyperlabel diagnostics for the data type check.
	SetValidation	Set a new validation rule for this field specification and new hyperlabel diagnostics for the validation rule check.
	Transform	Convert a specified value into a string, formatted according to this field specification's picture clause.
	Val	Convert a string to a value, according to this field specification's defined data type.
	Validate	A replaceable method for performing validations. The standard implementation evaluates the code block specified through FieldSpec:SetValidation().
