Constructor Detail

ArrayPrimitiveStore

public ArrayPrimitiveStore(Class clazz,
                           int size)

Constructs a new store. The supplied clazz must be a primitive type such as int.class.

Parameters:

clazz - primitive type to store

size - length of the vector

Method Detail

getType

public Class getType()

Description copied from interface: ValueStore

Returns the class of value which this object can store.

Specified by:

getType in interface ValueStore

Returns:

primitive class

getLength

public long getLength()

Description copied from interface: ValueStore

Returns the length of the vector.

Specified by:

getLength in interface ValueStore

Returns:

vector length

put

public void put(long index,
                Object array,
                int ioff,
                int count)

Description copied from interface: ValueStore

Stores a vector of values in this object. array must be an array of values matching getType. Element ioff of array is stored at index index, elemnt ioff+1 at index+1, etc.

Specified by:

put in interface ValueStore

Parameters:

index - starting offset to write to

array - array of values to store

ioff - offset into array from which the first value is taken

count - number of values to transfer

get

public void get(long index,
                Object array,
                int ioff,
                int count)

Description copied from interface: ValueStore

Retrieves a vector of values from this object. array must be an array of type matching getType. Every element of array will be filled with values; the first retrieved from offset index, the second from index+1, etc.

Specified by:

get in interface ValueStore

Parameters:

index - starting offset

array - array to accept data

ioff - offset into array to which the first value is copied

count - number of values to transfer
