Constructor Detail

GreaterThanOrEquals

public GreaterThanOrEquals(java.lang.String attrName,
                           java.lang.Object attrValue)
                    throws java.lang.NullPointerException

Create a GreaterThanOrEquals query expression. A profile will match the expression criteria if the value of the attrName attribute is greater than or equal to attrValue, as determined by Comparable.compareTo(Object).

Parameters:

attrName - the name of the profile attribute to compare.

attrValue - the value of the attribute to compare with.

Throws:

java.lang.NullPointerException - if either argument is null.

java.lang.IllegalArgumentException - if the class of attrValue does not implement the java.lang.Comparable interface.

GreaterThanOrEquals

public GreaterThanOrEquals(java.lang.String attrName,
                           java.lang.String attrValue,
                           QueryCollator collator)
                    throws java.lang.NullPointerException

Create a GreaterThanOrEquals query expression. A profile will match the expression criteria if the value of the attrName attribute is greater than or equal to attrValue, as determined by Collator.compare(String, String), where the collator is obtained from the specified QueryCollator.

Parameters:

attrName - the name of the profile attribute to compare.

attrValue - the value of the attribute to compare with.

collator - the collator to use for the comparison. May be null.

Throws:

java.lang.NullPointerException - if either attrName or attrValue is null.
