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

writeEnum

public void writeEnum(java.lang.CharSequence value)

Specified by:

writeEnum in interface MixedWritableValue

clone

public MixedWritableValue clone(WritableValue out)

Specified by:

clone in interface MixedWritableValue
