All Implemented Interfaces:

Expression

public class BindVariableAndExpression

extends AndExpression

Any contains(var) expression must be followed by at least one AND clause using the variable 'var'. This expression type represents one of those and AND clauses. It is responsible for evaluating the right subexpression for every possible value of the variable.
