Constructor Detail

XpathConstraintNode.Comparison

public XpathConstraintNode.Comparison(XpathHelper xpathHelper,
                                      String name)
Ctor

Parameters:
xpathHelper - The schema object
name - One of =, <>, <, <=, >, >=
Method Detail

translate

public XpathConstraintNode.XpathFragment translate(XpathConstraintNode.BindingContext ctx)

This compiles the node and its children to Xpath. Xpath can express all required comparison operators.

Specified by:
translate in class XpathConstraintNode
Parameters:
ctx - BindingContext this node shall be compiled in
Returns:
Object containing the SQL fragment and its operator priority
