public class Bindings extends NameValue
This class represnts a variable definitions in the RSL string (see rsl_substitution attribute)

  • Method Details

    • add

      public void add(Binding binding)
      Adds a new variable definition to the list.
      Parameters:
      binding - a new variable definition.
    • removeVariable

      public boolean removeVariable(String varName)
      Removes a specific variable definition from the list of bindings. The variable name must match exactly to be removed (it is case sensitive).
      Parameters:
      varName - variable name to remove the definition of.
      Returns:
      true if the variable was successfully removed. False, otherwise.
    • evaluate

      public Bindings evaluate(Map symbolTable) throws RslEvaluationException
      Evaluates the variable definitions as variable definitions can reference each other against the symbol table. The evaluation process updates the symbol table.
      Parameters:
      symbolTable - the symbol table to evalute the variables against.
      Returns:
      a new evaluted variable definition.
      Throws:
      RslEvaluationException - If an error occured during rsl evaluation.
    • toRSL

      public void toRSL(StringBuffer buf, boolean explicitConcat)
      Produces a RSL representation of this relation.
      Specified by:
      toRSL in class NameValue
      Parameters:
      buf - buffer to add the RSL representation to.
      explicitConcat - if true explicit concatination will be used in RSL strings.
