VariablesInfo
public VariablesInfo(NodeInfo parent, java.util.Map<java.lang.String,java.lang.String> vars, boolean local, java.lang.String composite, ConditionImpl cond)
Constructor.- Parameters:
vars
- a map of (String name, String value). Note: once called, the caller cannot access it any more. In other words, it becomes part of this object.local
- whether they are local variables.composite
- indicates the composite type. It can be one of "none", "list" or "map". If null or empty, "none" is assumed.- Throws:
java.lang.IllegalArgumentException
- if the composite type is illegal.- Since:
- 3.0.6
