Interface FieldValueInConstraint

All Superinterfaces:

Constraint, FieldConstraint

All Known Implementing Classes:

BasicFieldValueInConstraint

public interface FieldValueInConstraint

extends FieldConstraint

A constraint that restricts the value of a stepfield to be in a specified list of values.

This corresponds to the use of "in (...)" in SQL SELECT-syntax.

Method Detail

getValues

public java.util.SortedSet getValues()

Gets the list of values that is specified for this constraint, the values being represented by strings.

Numerical values are represented by strings using the standard floating point format. Integral numerical values, however, are represented by strings using the standard integer format, i.e. without the decimal point (e.g. "123" instead of "123.0").

toString

public java.lang.String toString()

Returns a string representation of this FieldValueInConstraint. The string representation has the form "FieldValueInConstraint(inverse:<:inverse>, field:<field>, casesensitive:<casesensitive>, values:<values>)" where

• <inverse>is the value returned by isInverse()
• <field> is the field alias returned by FieldConstraint#getField().getAlias()
• <casesensitive> is the value returned by isCaseSensitive()
• <values> is the values returned by getValues()

Returns:

A string representation of this FieldValueInConstraint.
