Constructor Detail

HeapTupleSchema

public HeapTupleSchema(HeapTupleSchema.Builder builder)
                throws java.lang.Exception

Throws:

java.lang.Exception

Method Detail

generateClass

protected void generateClass()
                      throws java.lang.Exception

Specified by:

generateClass in class TupleSchema

Throws:

java.lang.Exception

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

Throws:

java.lang.Exception - - Throws an exception if unable to allocate tuple or cast to the specified type

createTupleArray

public FastTuple[] createTupleArray(int size)
                             throws java.lang.Exception

Description copied from class: TupleSchema

Allocates an array of tuples. This method will try to ensure that tuples get allocated in adjacent memory, however with the heap based allocation this is not guaranteed.

Specified by:

createTupleArray in class TupleSchema

Parameters:

size - the number of tuples in the array.

Returns:

- Array of FastTuple

Throws:

java.lang.Exception - - Throws if unable to allocate tuple array

createTypedTupleArray

public <T> T[] createTypedTupleArray(java.lang.Class<T> clazz,
                                     int size)
                              throws java.lang.Exception

Description copied from class: TupleSchema

Parameters:

clazz - - Class implemented by the Tuple

size - - the number of tuples in the array

Returns:
