ValueRangeConstraint
public ValueRangeConstraint(java.lang.Number lower,
java.lang.Number upper)
- Creates a new value range constraint from the given boundaries.
The value boundaries are considered inclusive.
- Parameters:
lower - the lower boundary, or MIN for unlimitedupper - the upper boundary, or MAX for unlimited
ValueRangeConstraint
public ValueRangeConstraint(java.lang.Number lower,
boolean lowinc,
java.lang.Number upper,
boolean upinc)
- Creates a new value range constraint from the given boundaries.
The value boundaries can be made either inclusive or exclusive.
Note that in the latter case a value of one is just added or
subtracted to the value.
- Parameters:
lower - the lower boundary, or MIN for unlimitedlowinc - true if lower boundary inclusive,
false otherwiseupper - the upper boundary, or MAX for unlimitedupinc - true if upper boundary inclusive,
false otherwise
equals
public boolean equals(java.lang.Object obj)
- Checks if this constraint equals another constraint.
- Overrides:
equals in class Constraint
- Parameters:
obj - the object to compare with- Returns:
- true if the objects are equal, or
false otherwise
toString
public java.lang.String toString()
- Returns a string description of this constraint.
- Overrides:
toString in class Constraint
- Returns:
- a string description
transferConstraint
public void transferConstraint(TypeConverter converter)
- Transfers the constraint information from this object to a type
converter object. The calling conventions declared in the
TypeConverter class are followed.
- Overrides:
transferConstraint in class Constraint
- Parameters:
converter - a type converter
minValue
protected int minValue()
- Returns the minimum integer value for this constraint.
- Returns:
- the minium integer value
maxValue
protected int maxValue()
- Returns the maximum integer value for this constraint.
- Returns:
- the maximum integer value
