Method Summary

Modifier and Type	Method	Description
abstract ABooleanArray	clone()	Overwrite of the java internal clone function for arrays, return a clone of underlying data that is mutable, (not immutable data.) Immutable data is dependent on the individual allocated arrays
abstract boolean	isAllTrue()
boolean	possiblyContainsNaN()
abstract ABooleanArray	select(boolean[] select, int nTrue)	Slice out the true indices in the select input and return the sub array.
abstract ABooleanArray	select(int[] indices)	Slice out the specified indices and return the sub array.
abstract void	setNullsFromString(int rl, int ru, Array<String> value)	set boolean values in this array depending on null positions in the string array.
abstract ABooleanArray	slice(int rl, int ru)	Slice out the sub range and return new array with the specified type.

Method Details

isAllTrue

public abstract boolean isAllTrue()

slice

public abstract ABooleanArray slice(int rl,
 int ru)

Description copied from class: Array

Slice out the sub range and return new array with the specified type. If the conversion fails fallback to normal slice.

Specified by:

slice in class Array<Boolean>

Parameters:

rl - row start

ru - row end (not included)

Returns:

A new array of sub range.

clone

public abstract ABooleanArray clone()

Description copied from class: Array

Overwrite of the java internal clone function for arrays, return a clone of underlying data that is mutable, (not immutable data.) Immutable data is dependent on the individual allocated arrays

Specified by:

clone in class Array<Boolean>

Returns:

A clone

select

public abstract ABooleanArray select(int[] indices)

Description copied from class: Array

Slice out the specified indices and return the sub array.

Specified by:

select in class Array<Boolean>

Parameters:

indices - The indices to slice out

Returns:

the sliced out indices in an array format

select

public abstract ABooleanArray select(boolean[] select,
 int nTrue)

Description copied from class: Array

Slice out the true indices in the select input and return the sub array.

Specified by:

select in class Array<Boolean>

Parameters:

select - a boolean vector specifying what to select

nTrue - number of true values inside select

Returns:

the sliced out indices in an array format

possiblyContainsNaN

public boolean possiblyContainsNaN()

Specified by:

possiblyContainsNaN in class Array<Boolean>

setNullsFromString

public abstract void setNullsFromString(int rl,
 int ru,
 Array<String> value)

set boolean values in this array depending on null positions in the string array.

Parameters:

rl - Inclusive lower bound

ru - Exclusive upper bound

value - The string array to set from.
