Method Summary

static LLRPArrayConstraint	getArrayConstraint(java.lang.Object messageOrParameter, java.lang.String fieldName, LLRPTreeMaintainer treeMaintainer) Returns the array constraint that is specified for the given field, or null if there is no such constraint.
static LLRPRangeConstraint	getRangeConstraint(java.lang.Object messageOrParameter, java.lang.String fieldName, LLRPTreeMaintainer treeMaintainer) Returns the range constraint that is specified for the given field, or null if there is no such constraint.

Method Detail

getRangeConstraint

public static LLRPRangeConstraint getRangeConstraint(java.lang.Object messageOrParameter,
                                                     java.lang.String fieldName,
                                                     LLRPTreeMaintainer treeMaintainer)

Returns the range constraint that is specified for the given field, or null if there is no such constraint. The constraint is only returned if the given field matches the constraints precondition.

Parameters:

messageOrParameter -

fieldName -

treeMaintainer -

Returns:

a range constraint for a given field if exists, null otherwise.

getArrayConstraint

public static LLRPArrayConstraint getArrayConstraint(java.lang.Object messageOrParameter,
                                                     java.lang.String fieldName,
                                                     LLRPTreeMaintainer treeMaintainer)

Returns the array constraint that is specified for the given field, or null if there is no such constraint.

Parameters:

messageOrParameter -

fieldName -

treeMaintainer -

Returns:

llrp constraint if there is a constraint, null otherwise.
