setArrayLength

public void setArrayLength(int len)

Description copied from interface: WritableValue

Set length of the array. It must be called prior to nextWritableElement

Specified by:

setArrayLength in interface WritableValue

Parameters:

len - length of the array

nextWritableElement

public WritableValue nextWritableElement()

Description copied from interface: WritableValue

Returns a transient (reused by interface implementation) WritableValue object for the next element of the array.

WritableValue.setArrayLength(int) method must be called before this method.
Client code must not cache the reference for further usage.
Usage sample:

  encoder.setArrayLength(10);
  for(int i=0; i<10; i++) {
      WritableValue v = encoder.nextWritableElement (i);
      v.setInt(i);
  }
 

Specified by:

nextWritableElement in interface WritableValue

Returns:

reference to WritableValue object

getFieldEncoder

public UnboundEncoder getFieldEncoder(RecordClassDescriptor rcd)

Specified by:

getFieldEncoder in interface WritableValue

getBoxedValue

protected abstract java.lang.Object getBoxedValue()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
