valueOf

public static RFldConstraintI8MinMax valueOf(java.lang.String key,
                                             java.lang.String fldName,
                                             boolean minSet,
                                             java.lang.Byte min,
                                             boolean maxSet,
                                             java.lang.Byte max)
                                      throws FieldValidationException

Factory. Returns a RFldConstraintF32MinMax instance based on the input parameters.

Parameters:

key - Key to use for caching constraint.

fldName - Name of field to which this constraint is bound.

minSet - Flag to indicate whether min value is set.

min - Minimum length allowed. If this is null then no constraint is placed on the minimum length.

maxSet - Flag to indicate whether max value is set.

max - Maximum length allowed. If this is null then no constraint is placed on the maximum length.

Throws:

FieldValidationException

errDesc

public java.lang.String errDesc(java.lang.String fldName)

Get error description.

Specified by:

errDesc in interface RFldConstraint

Specified by:

errDesc in class RFldConstraintI8

Parameters:

fldName - Field name.

Returns:

Error description.

isValid

public boolean isValid(byte val)

Check if a value satisfies the constraint.

Specified by:

isValid in class RFldConstraintI8

Parameters:

val - Field value to validate.

Returns:
