mSuffixes
Constructors Summary
public ComplexValue(Expression pPrefix, List pSuffixes)
Constructor

    mPrefix = pPrefix;
    mSuffixes = pSuffixes;
Methods Summary
public java.lang.Objectevaluate(java.lang.Object pContext, VariableResolver pResolver, java.util.Map functions, java.lang.String defaultPrefix, Logger pLogger)
Evaluates by evaluating the prefix, then applying the suffixes

    Object ret = mPrefix.evaluate (pContext, pResolver, functions,
				   defaultPrefix, pLogger);

    // Apply the suffixes
    for (int i = 0; mSuffixes != null && i < mSuffixes.size (); i++) {
      ValueSuffix suffix = (ValueSuffix) mSuffixes.get (i);
      ret = suffix.evaluate (ret, pContext, pResolver, functions,
			     defaultPrefix, pLogger);
    }

    return ret;
public java.lang.StringgetExpressionString()
Returns the expression in the expression language syntax

    StringBuffer buf = new StringBuffer ();
    buf.append (mPrefix.getExpressionString ());

    for (int i = 0; mSuffixes != null && i < mSuffixes.size (); i++) {
      ValueSuffix suffix = (ValueSuffix) mSuffixes.get (i);
      buf.append (suffix.getExpressionString ());
    }

    return buf.toString ();
