Method Detail

add

public boolean add(StatusLevelTag statusLevel,
                   java.lang.Object value)

Adds a Comparison object containing the given parameters to this object's list. Note that the 'value' objects must all be of the same type and Comparable values must be in ascending order (where each 'value' is larger than the previous one).

Parameters:

statusLevel - handle of a StatusLevelTag object.

value - an object containing the value to be associated with the given status level (such as an 'Integer', 'Double', etc.)

Returns:

true if successful, false otherwise.

add

public boolean add(Comparison cObj)

Adds the given Comparison object to this object's list. Note that the 'value' objects must all be of the same type and Comparable values must be in ascending order (where each 'value' is larger than the previous one).

Parameters:

cObj - the Comparison object.

Returns:

true if successful, false otherwise.

valueToStatus

public StatusLevelTag valueToStatus(java.lang.Object value)

Translates the given value to a status level using this object's list of Comparison objects.

Parameters:

value - an object containing the value to be translated.

Returns:

The StatusLevelTag object for the given value (returns 'StatusLevelTag.unknownStatusTag' if the given value is null or if it is lower than the minimum value in the list).

Throws:

java.lang.ClassCastException - if the given object's type prevents it from being compared to the objects in the list.

getValueClass

public java.lang.Class getValueClass()

Returns the class type object for the values in the comparison list, or null if no objects exist in the list.

getComparisonSet

public java.util.Vector getComparisonSet()

Returns the Vector of 'Comparison' objects that make up the comparison set for this criteria.

toString

public java.lang.String toString()

Returns a string representation of this object. The string representation of each 'Comparison' object is put on a separate indented line.

Overrides:

toString in class java.lang.Object
