Joins all expressions, making a single expression.type
is used as an expression type for expressions joining each one of the items in the array.type
must be binary expression type.For example, if type is Expression.AND, resulting expression would match all expressions in the list. If type is Expression.OR, resulting expression would match any of the expressions.

exp
public static Expression exp(String expressionString, Object... parameters)
Parses string, converting it to Expression and optionally binding positional parameters. If a string does not represent a semantically correct expression, an ExpressionException is thrown.Binding of parameters by name (as opposed to binding by position) can be achieved by chaining this call with
Expression.params(Map)
