Method Detail

get

public final boolean get(int index)

Gets the value at a given index. If an undefined or non-boolean value exists at the given index, a type-conversion error will occur in Development Mode and unpredictable behavior may occur in Production Mode.

Parameters:

index - the index to be retrieved

Returns:

the value at the given index

join

public final String join()

Convert each element of the array to a String and join them with a comma separator. The value returned from this method may vary between browsers based on how JavaScript values are converted into strings.

join

public final String join(String separator)

Convert each element of the array to a String and join them with a comma separator. The value returned from this method may vary between browsers based on how JavaScript values are converted into strings.

length

public final int length()

Gets the length of the array.

Returns:

the array length

push

public final void push(boolean value)

Pushes the given boolean onto the end of the array.

set

public final void set(int index,
       boolean value)

Sets the value value at a given index. If the index is out of bounds, the value will still be set. The array's length will be updated to encompass the bounds implied by the added value.

Parameters:

index - the index to be set

value - the value to be stored

setLength

public final void setLength(int newLength)

Reset the length of the array.

Parameters:

newLength - the new length of the array

shift

public final boolean shift()

Shifts the first value off the array.

Returns:

the shifted value

unshift

public final void unshift(boolean value)

Shifts a value onto the beginning of the array.

Parameters:

value - the value to the stored
