Method Details

create

public static <T extends ACell> AVector<T> create(ACell[] elements,
 int offset,
 int length)

Creates a canonical AVector with the given elements

Parameters:

elements - Elements to include

offset - Offset into element array

length - Number of elements to take

Returns:

New vector with the specified elements

create

public static <T extends ACell> AVector<T> create(ACell[] elements)

Create a vector from an array of elements.

Type Parameters:

T - Type of elements

Parameters:

elements - Elements to include

Returns:

New vector with the specified elements

create

public static <R extends ACell,
T extends ACell>
AVector<R> create(Collection<?> elements)

Coerces a collection to a vector. Not necessarily the most efficient. Performs an unchecked cast.

Type Parameters:

R - Type of Vector elements to produce

T - Type of source collection elements

Parameters:

elements - Elements to include

Returns:

New vector with the specified collection of elements

create

public static <R extends ACell,
T extends ACell>
AVector<R> create(ASequence<R> list)

empty

public static <T extends ACell> AVector<T> empty()

of

@SafeVarargs
public static <T extends ACell> AVector<T> of(Object... elements)

Creates a vector with the given values. Performs conversion to CVM types.

Type Parameters:

T - Type of elements (after CVM conversion)

Parameters:

elements - Elements to include

Returns:

New Vector

repeat

public static <T extends ACell> AVector<T> repeat(T m,
 int count)

read

public static <T extends ACell> AVector<T> read(ByteBuffer bb)
                                         throws BadFormatException

Reads a Vector for the specified bytebuffer. Assumes Tag byte already consumed. Distinguishes between child types according to count.

Type Parameters:

T - Type of elements

Parameters:

bb - ByteBuffer to read from

Returns:

Vector read from ByteBuffer

Throws:

BadFormatException - If encoding is invalid
