Class RhinoExpression

java.lang.Object

org.pentaho.reporting.engine.classic.core.function.AbstractExpression

org.pentaho.reporting.engine.classic.extensions.modules.rhino.RhinoExpression

All Implemented Interfaces:

Serializable, Cloneable, org.pentaho.reporting.engine.classic.core.function.Expression

public class RhinoExpression
extends org.pentaho.reporting.engine.classic.core.function.AbstractExpression
implements Serializable

Deprecated.

Use BSHExpression instead.

An expression that uses the Rhino scripting framework to perform a scripted calculation. The expression itself is contained in a function called

Object getValue()

and this function is defined in the expression property. You have to overwrite the function getValue() to begin and to end your expression, but you are free to add your own functions to the script.

Deprecated.

getValue

public Object getValue()

Deprecated.

Evaluates the defined expression. If an exception or an evaluation error occures, the evaluation returns null and the error is logged. The current datarow and a copy of the expressions properties are set to script-internal variables. Changes to the properties will not alter the expressions original properties and will be lost when the evaluation is finished.

Expressions do not maintain a state and no assumptions about the order of evaluation can be made.

Specified by:

getValue in interface org.pentaho.reporting.engine.classic.core.function.Expression

Returns:

the evaluated value or null.

getExpression

public String getExpression()

Deprecated.

setExpression

public void setExpression(String expression)

Deprecated.
