Interface FieldValueBetweenConstraint

All Superinterfaces:

Constraint, FieldConstraint

All Known Implementing Classes:

BasicFieldValueBetweenConstraint

public interface FieldValueBetweenConstraint

extends FieldConstraint

A constraint that restricts the value of a stepfield to be in a specified range of values (numerical or string).

This corresponds to the use of "between ... and ..." in SQL SELECT-syntax.

Method Detail

getLowerLimit

public java.lang.String getLowerLimit()

Gets the value of the lower limit of the range specified for this constraint, represented by a string.

A numerical value is represented by a string using the standard floating point format. An integral numerical value, however, is represented by a string using the standard integer format, i.e. without the decimal point (e.g. "123" instead of "123.0").

getUpperLimit

public java.lang.String getUpperLimit()

Gets the value of the upper limit of the range specified for this constraint, represented by a string.

A numerical value is represented by a string using the standard floating point format. An integral numerical value, however, is represented by a string 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 FieldValueBetweenConstraint. The string representation has the form "FieldValueBetweenConstraint(inverse:<:inverse>, field:<field>, casesensitive:<casesensitive>, lower:<lowerLimit>, upper:<upperLimit>)" 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()
• <lowerLimit> is the values returned by getValues()
• <upperLimit> is the values returned by getValues()

Returns:

A string representation of this FieldValueInConstraint.
