    • getVarType

      public VarType getVarType()
      Returns the material parameter type.
      Returns:
      the material parameter type.

    • getValue

      public Object getValue()
      Returns the value of this material parameter.

      Material parameters that are used for material definitions will not have a value, unless there's a default value declared in the definition.

      Returns:
      the value of this material parameter.

    • setValue

      public void setValue(Object value)
      Sets the value of this material parameter.

      It is assumed the value is of the same type as this material parameter.

      value - the value of this material parameter.

    • getValueAsString

      public String getValueAsString()
      Returns the material parameter value as it would appear in a J3M file. E.g. 
       MaterialParameters {
     ABC : 1 2 3 4
 }
      Assuming "ABC" is a Vector4 parameter, then the value "1 2 3 4" would be returned by this method.
      Returns:
      material parameter value as it would appear in a J3M file.
