ExpressionString

• java.lang.Object

Fields Summary
Object[]	mElements

Constructors Summary
public ExpressionString(Object[] pElements) Constructor mElements = pElements;

Methods Summary
public java.lang.String	evaluate(java.lang.Object pContext, VariableResolver pResolver, java.util.Map functions, java.lang.String defaultPrefix, Logger pLogger) Evaluates the expression string by evaluating each element, converting it to a String (using toString, or "" for null values) and concatenating the results into a single String. StringBuffer buf = new StringBuffer (); for (int i = 0; i < mElements.length; i++) { Object elem = mElements [i]; if (elem instanceof String) { buf.append ((String) elem); } else if (elem instanceof Expression) { Object val = ((Expression) elem).evaluate (pContext, pResolver, functions, defaultPrefix, pLogger); if (val != null) { buf.append (val.toString ()); } } } return buf.toString ();
public java.lang.Object[]	getElements() return mElements;
public java.lang.String	getExpressionString() Returns the expression in the expression language syntax StringBuffer buf = new StringBuffer (); for (int i = 0; i < mElements.length; i++) { Object elem = mElements [i]; if (elem instanceof String) { buf.append ((String) elem); } else if (elem instanceof Expression) { buf.append ("${"); buf.append (((Expression) elem).getExpressionString ()); buf.append ("}"); } } return buf.toString ();
public void	setElements(java.lang.Object[] pElements) mElements = pElements;
