Interface RVectorFactor<WRAPPED_TYPE,ARR_TYPE,EL_TYPE>

Type Parameters:

WRAPPED_TYPE - underlying type of the used back-end, see RObj

ARR_TYPE - used Java array to store the data.

EL_TYPE - boxed type of an element of ARR_TYPE. Extends Object. Example: For RInteger ARR_TYPE equals int[] and

Method Detail

getLength

int getLength()

Returns the number of elements in this vector/factor.

Returns:

the number of elements in this vector/factor

getData

ARR_TYPE getData()

Returns an array containing all of the elements in this vector/factor in proper sequence

Returns:

an array containing all of the elements in this vector/factor in proper sequence

getDataAsObjArr

EL_TYPE[] getDataAsObjArr()

Returns an array containing all of the elements in this vector/factor in proper sequence. If getData() returns an array of primitives, this methods converts to an array of Java Objects. Note that this takes linear time for long arrays.

Returns:

an array containing all of the elements in this vector/factor in proper sequence

getDataAsList

List<EL_TYPE> getDataAsList()

Returns a list containing all of the elements in this vector/factor in proper sequence

Returns:

a list containing all of the elements in this vector/factor in proper sequence

get

EL_TYPE get(int i)

Returns the element at the specified position in this vector/factor.

Parameters:

i - index of the element to return

Returns:

the element at the specified position in this vector/factor

Throws:

IndexOutOfBoundsException - if the index is out of range (index < 0 || index >= getLength())

getName

String getName(int i)

Returns the name at the specified position of this vector/factor. If the name is not set RCallServices.NA_CHAR is returned.

Parameters:

i - index of the position

Returns:

the name of the specified position of this vector/factor

getNames

String[] getNames()

If no name is set null is returned. Otherwise returns a String Array of length equal to getLength() that contains the names of the positions in this vector/factor. If a name is not set RCallServices.NA_CHAR is used.

Returns:

the names of this vector/factor

getNamesAsList

List<String> getNamesAsList()

If no name is set null is returned. Returns a List of Strings of size equal to getLength() that contains the names of the positions in this vector/factor. If a name is not set RCallServices.NA_CHAR is used.

Returns:

the names of this vector/factor

isNA

boolean isNA(int i)

Returns true if the specified element is NA.

Parameters:

i - index of the element to test for NA

Returns:

true if the specified element is NA
