Constructor Detail

SVarSet

public SVarSet()

default constructor of empty dataset

Method Detail

setMarker

public void setMarker(SMarker m)

sets the marker for this dataset

Parameters:

m - marker

getMarker

public SMarker getMarker()

returns the marker of this dataset

Returns:

marker

setName

public void setName(java.lang.String s)

set dataset name

Parameters:

s - name

getName

public java.lang.String getName()

get dataset name

Returns:

dataset name

length

public int length()

add

public int add(SVar v)

add a new variable to the dataset

Parameters:

v - variable

Returns:

index of the newly create variable or <0 if an error occured (-1 on null-problems, -2 if that variable-name already exists)

insert

public void insert(int index,
                   SVar v)

add a new empty variable to the dataset

Parameters:

index - index

size - size of SVar

isnum - numbers

cat - categorical /* added 28.12.03 MH

insert

public void insert(java.lang.String name,
                   int index,
                   SVar v)

move

public void move(int from,
                 int to)

move a variable's to a new index

Parameters:

from - from index

to - to index /* added 24.02.04 MH

remove

public void remove(int index)

removes a variable of the dataset at specified index

Parameters:

index - index

insertCaseAt

public boolean insertCaseAt(int index)

add an empty case to the set

Parameters:

index - index

removeCaseAt

public boolean removeCaseAt(int index)

delete a case of the set

Parameters:

index - index

indexOf

public int indexOf(java.lang.String nam)

returns the index of a variable specified by its name

Parameters:

nam - variable name

Returns:

index of the variable (or -1 if not found)

byName

public SVar byName(java.lang.String nam)

returns variable object specified by name

Parameters:

nam - variable name

Returns:

variable object or null if not found.

at

public SVar at(int i)

returns variable object at specified index

Parameters:

i - index

Returns:

variable object or null if index out of range

replace

public void replace(int i,
                    SVar v)

repaces a variable at the specified index. Use with extreme care! Should be used only in the loading stage before the variable is ever used, in order to provide optimized version of the same variable once the type is known.
