createTuple

public FastTuple createTuple()
                      throws java.lang.Exception

Description copied from class: TupleSchema

Allocates a new tuple, completely separate from any pooling.

Specified by:

createTuple in class TupleSchema

Returns:

- FastTuple

Throws:

java.lang.Exception - - Throws an exception if unable to allocate tuple

createTypedTuple

public <T> T createTypedTuple(java.lang.Class<T> clazz)
                       throws java.lang.Exception

Description copied from class: TupleSchema

Allocates a new typed tuple, completely separate from any pooling. Use care to call TupleSchema.Builder.implementInterface(Class) before using this method

Specified by:

createTypedTuple in class TupleSchema

Type Parameters:

T - - TupleSchema type parameter

Parameters:

clazz - - Class implemented by the Tuple

Returns:

- FastTuple case to type TupleSchema
