Method Detail

getType

Class<?> getType()

Returns the class of value which this object can store.

Returns:

primitive class

getLength

long getLength()

Returns the length of the vector.

Returns:

vector length

put

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

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.

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

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

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.

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
