## com.bea.p13n.expression.operator.string
Class StringReplace

    java.lang.Object
      com.bea.p13n.expression.internal.ComplexExpressionImpl
          com.bea.p13n.expression.operator.Operator
              com.bea.p13n.expression.operator.string.StringOperator
                  com.bea.p13n.expression.operator.string.StringReplace

All Implemented Interfaces:
  Cloneable, Expression, com.bea.p13n.expression.ExpressionEvents, Serializable

public final class StringReplace
extends StringOperator

Implementation of the StringReplace operator.
Input 1: A String (or Expression returning a String) that is LHS of the operator.
Input 2: A Character (or Expression returning a Character) that is character to be replaced (RHS).
Input 3: A Character (or Expression returning a Character) that is the new character that should be inserted (RRHS).
Returns: A String: LHS.replace( RHS, RRHS ).

Constructor Detail

### StringReplace

    public StringReplace()

### StringReplace

    public StringReplace(Object string,
                         Object oldChar,
                         Object newChar)

Method Detail

### getParameterSignature

    public Class[] getParameterSignature()

  Description copied from interface: `Expression`
  Returns the parameter signature for this `Expression`. Because the sub-expressions within the `Expression` are typically arguments or operands, some type validation is performed by examining the class types of the sub-expressions against the `Expression`'s parameter signature.
  The tests that are performed are:
  1. The number of sub-expressions must equals the number of parameter entries.
  2. The class type of any sub-expression (or the result of evaluating the sub-expresssion) must equal the class type of the corresponding parameter entry.
  3. Any null parameter entries are ignored and are considered optional sub-expressions.

  Returns:
    the Class array containing the parameter signature.
