public abstract class SchemaTuple<T extends SchemaTuple<T>>
extends AbstractTuple
implements TypeAwareTuple
```
A SchemaTuple is a type aware tuple that is much faster and more memory efficient. In our implementation, given a Schema, code generation is used to extend this class. This class provides a broad range of functionality that minimizes the complexity of the code that must be generated. The odd looking generic signature allows for certain optimizations, such as "setSpecific(T t)", which allows us to do much faster sets and comparisons when types match (since the code is generated, there is no other way to know).

Method Detail

append
```
public void append(java.lang.Object val)
```
Description copied from interface: Tuple

Append a field to a tuple. This method is not efficient as it may force copying of existing data in order to grow the data structure. Whenever possible you should construct your Tuple with TupleFactory.newTuple(int) and then fill in the values with Tuple.set(int, Object), rather than construct it with TupleFactory.newTuple() and append values.

Specified by:

append in interface Tuple

Parameters:
val - Object to append to the tuple.

getMemorySize
```
public long getMemorySize()
```
This only accounts for the size of members (adjusting for word alignment). It also includes the size of the object itself, since this never affects word boundaries.

Specified by:

getMemorySize in interface Tuple

Returns:
estimated memory size, in bytes.

getGeneratedCodeMemorySize

protected abstract long getGeneratedCodeMemorySize()

getSchemaTupleIdentifier
```
public abstract int getSchemaTupleIdentifier()
```
This method will return the identifier that the generated code was generated with. This is useful because when the classes are resolved generically, this let's us know the identifier, which is used when serlializing and deserializing tuples.

Returns:
the identifire as Int.

Description copied from interface: Tuple

Set the value in a given field. This should not be called unless the tuple was constructed by TupleFactory.newTuple(int) with an argument greater than the fieldNum being passed here. This call will not automatically expand the tuple size. That is if you called TupleFactory.newTuple(int) with a 2, it is okay to call this function with a 1, but not with a 2 or greater.

Specified by:

set in interface Tuple

Parameters:
fieldNum - Number of the field to set the value for.
val - Object to put in the indicated field.

Throws:

ExecException - if the field number is greater than or equal to the number of fields in the tuple.

This method is responsible for writing everything contained by the Tuple. Note that the base SchemaTuple class does not have an implementation (but is not abstract) so that the generated code can call this method via super without worrying about whether it is abstract or not, as there may be classes in between in the inheritance tree (such as AppendableSchemaTuple).

Parameters:
out -

Throws:

java.io.IOException
