Class SubStringExpression

java.lang.Object
  org.pentaho.reporting.engine.classic.core.function.AbstractExpression
      org.pentaho.reporting.engine.classic.core.function.strings.SubStringExpression

All Implemented Interfaces:

Serializable, Cloneable, Expression

Deprecated. Use a formula

public class SubStringExpression
extends AbstractExpression

Creates a substring of the given text. If the expression has an ellipsis defined, and the given start position and length are greater than the string's length, the ellipsis-text will be appended to indicate that this substring result is only a partial match.

A similiar functionality can be achived using the built-in formula support.
