Constructor Detail

BasicFieldValueInConstraint

public BasicFieldValueInConstraint(StepField field)

Constructor.

Parameters:

field - The associated field.

Method Detail

addValue

public BasicFieldValueInConstraint addValue(java.lang.Object value)

Adds value.

Parameters:

value - The value.

Returns:

This BasicFieldValueInConstraint instance.

Throws:

java.lang.IllegalArgumentException - when an invalid argument is supplied.

See Also:

FieldValueInConstraint.getValues()

getValues

public java.util.SortedSet getValues()

Description copied from interface: FieldValueInConstraint

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").

Specified by:

getValues in interface FieldValueInConstraint

equals

public boolean equals(java.lang.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

hashCode

public int hashCode()

Specified by:

hashCode in interface Constraint

Overrides:

hashCode in class BasicFieldConstraint

toString

public java.lang.String toString()

Description copied from interface: FieldValueInConstraint

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()
