- Method Detail
  - getValue
```
Number getValue()
```
    Gets a unique value for nodata. It doesn't take into account if the raster has several bands. Returns the same value for all of them.
    
    Returns:
    
    the noData
  - setValue
```
void setValue(Number noData)
```
    Sets a unique value for nodata. It doesn't take into account if the raster has several bands. Assigns the same value for all of them.
    
    Parameters:
    
    noData - the noData to set
  - isDefined
```
boolean isDefined()
```
    Returns true if getValue is defined and false if is null
    
    Returns:
  - delete
```
void delete()
```
    Deletes the nodata value.
  - restore
```
void restore()
```
    Restores native value. The native is the original value saved in the head of the file or its metadata. This value has to be assign when NoData object is initialize.
  - getNativeValue
```
Number getNativeValue()
```
    The native is the original value saved in the head of the file or its metadata. This value has to be assign when NoData object is initialize
    
    Returns:
    
    the noData
  - setNativeValue
```
void setNativeValue(Number nativeNoDataValue)
```
    The native is the original value saved in the head of the file or its metadata. This value has to be assign when NoData object is initialize.
    
    Parameters:
    
    nativeNoDataValue -
  - setFileName
```
void setFileName(String fileName)
```
    Sets the file name
    
    Parameters:
    
    bandCount -
  - getFileName
```
String getFileName()
```
    Gets the file name
    
    Returns:
  - isNoDataTransparent
```
boolean isNoDataTransparent()
```
    Flag to renderize nodata values as transparent
    
    Returns:
  - setNoDataTransparent
```
void setNoDataTransparent(boolean noDataAsTransparent)
```
    Flag to renderize nodata values as transparent
    
    Parameters:
    
    noDataAsTransparent -
  - getDataType
```
int getDataType()
```
    Gets the NoData data type
    
    Returns:

```
void setDataType(int datatype)
```
    Sets the datatype
  - compare
```
boolean compare(BufferNoData noData)
```

```
    Creates and returns a copy of this object.
    
    Returns:
  - getValueByBand
```
Number getValueByBand(int nBand)
```
    Gets the nodata value by band
    
    Parameters:
