Constructor Detail

BasicFieldValueBetweenConstraint

public BasicFieldValueBetweenConstraint(StepField field,
                                        Object lowerLimit,
                                        Object upperLimit)

Constructor.

Depending on the field type, the limit values must be of type String or Number.

Parameters:

field - The associated field.

lowerLimit - The lower limit.

upperLimit - The upper limit.

Throws:

IllegalArgumentException - when an invalid argument is supplied.

Method Detail

setLowerLimit

public BasicFieldValueBetweenConstraint setLowerLimit(Object lowerLimit)

Sets the lower limit property.

Depending on the field type, the value must be of type String or Number.

Parameters:

lowerLimit - The non-null lower limit property value.

Returns:

This BasicFieldValueBetweenConstraint instance.

Throws:

IllegalArgumentException - when an invalid argument is supplied.

setUpperLimit

public BasicFieldValueBetweenConstraint setUpperLimit(Object upperLimit)

Sets the upper limit property.

Depending on the field type, the value must be of type String or Number.

Parameters:

upperLimit - The non-null upper limit property value.

Returns:

This BasicFieldValueBetweenConstraint instance.

Throws:

IllegalArgumentException - when an invalid argument is supplied.

getLowerLimit

public Object getLowerLimit()

Description copied from interface: FieldValueBetweenConstraint

Gets the value of the lower limit of the range specified for this constraint.

Specified by:

getLowerLimit in interface FieldValueBetweenConstraint

getUpperLimit

public Object getUpperLimit()

Description copied from interface: FieldValueBetweenConstraint

Gets the value of the upper limit of the range specified for this constraint.

Specified by:

getUpperLimit in interface FieldValueBetweenConstraint

equals

public boolean equals(Object obj)

Description copied from interface: Constraint

Compares this constraint to the specified object. The result is true if and only if the argument is a non-null Constraint object representing the same constraint(s).

Specified by:

equals in interface Constraint

Overrides:

equals in class BasicFieldConstraint

Parameters:

obj - The object to compare with.

Returns:

true if the objects are equal, false otherwise.

hashCode

public int hashCode()

Specified by:

hashCode in interface Constraint

Overrides:

hashCode in class BasicFieldConstraint

toString

public String toString()

Description copied from interface: FieldValueBetweenConstraint

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()

Specified by:

toString in interface FieldValueBetweenConstraint

Overrides:

toString in class BasicFieldConstraint

Returns:

A string representation of this FieldValueInConstraint.
