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
