public interface IonDatagram extends IonSequence
WARNING: This interface should not be implemented or extended by code outside of this library. Some inherited methods are not yet implemented or are unsupported for datagrams.
Along with the normal user values, datagrams contain system values, notably
the symbol table(s) used to atomize all symbols. Most uses of a datagram
will not see system values,
but applications that need visibility into that data can use the
system*()
methods.
EMPTY_ARRAY
Modifier and Type | Method and Description |
---|---|
ValueFactory |
add(int index)
This inherited method is not yet supported by datagrams.
|
void |
add(int index,
IonValue element)
This inherited method is not yet supported by datagrams.
|
boolean |
addAll(int index,
Collection<? extends IonValue> c)
This inherited method is not yet supported by datagrams.
|
void |
addTypeAnnotation(String annotation)
This inherited method is not supported by datagrams.
|
int |
byteSize()
Gets the number of bytes used to encode this datagram.
|
IonDatagram |
clone()
Creates a copy of this value and all of its children.
|
IonValue |
get(int index)
Gets a selected non-system element from this datagram.
|
byte[] |
getBytes()
Copies the binary-encoded form of this datagram into a new byte array.
|
int |
getBytes(OutputStream out)
Copies the binary-encoded form of this datagram to a specified stream.
|
IonContainer |
getContainer()
Gets the container of this value,
or
null if this is not part of one. |
SymbolTable |
getSymbolTable()
This inherited method is not supported by datagrams because there's no
single symbol table used across the contents.
|
boolean |
isNullValue()
Returns
false at every call, since datagrams cannot be null. |
Iterator<IonValue> |
iterator()
Creates an iterator providing the (direct) elements of this datagram.
|
void |
makeNull()
This inherited method is not supported by datagrams.
|
boolean |
retainAll(Collection<?> c)
This inherited method is not yet supported by datagrams.
|
IonValue |
set(int index,
IonValue element)
This inherited method is not yet supported by datagrams.
|
int |
size()
Gets the number of elements in the datagram, not counting system
elements.
|
IonValue |
systemGet(int index)
Gets a selected element from this datagram, potentially getting a
hidden system element (such as a symbol table).
|
ListIterator<IonValue> |
systemIterator()
Iterate all values in the datagram, including the otherwise-hidden
system values such as version markers and symbol tables.
|
int |
systemSize()
Gets the number of elements in the datagram, including system elements
such as version markers and symbol tables.
