public class JsArrayMixed
extends JavaScriptObject

A simple wrapper around an heterogeneous native array of values. This class may not be directly instantiated, and can only be returned from a native method. For example, native JsArrayMixed getNativeArray() /*-{ return [ { x: 0, y: 1}, "apple", 12345, ]; }-* /;

Method Details

getBoolean

public final boolean getBoolean(int index)

Gets the boolean at a given index.

Parameters:

index - the index to be retrieved

Returns:

the object at the given index coerced to boolean.

getNumber

public final double getNumber(int index)

Gets the double at a given index.

Parameters:

index - the index to be retrieved

Returns:

the object at the given index coerced to number.

getObject

public final <T extends JavaScriptObject> T getObject(int index)

Gets the JavaScriptObject at a given index.

Parameters:

index - the index to be retrieved

Returns:

the JavaScriptObject at the given index, or null if none exists

getString

public final String getString(int index)

Gets the String at a given index.

Parameters:

index - the index to be retrieved

Returns:

the object at the given index, or null if none exists

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.

push

public final void push(double value)

Pushes the given double onto the end of the array.

push

public final void push(JavaScriptObject value)

Pushes the given JavaScriptObject onto the end of the array.

push

public final void push(String value)

Pushes the given String onto the end of the array.

set

public final void set(int index,
 boolean value)

Sets the boolean 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 boolean to be stored

set

public final void set(int index,
 double value)

Sets the double 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 double to be stored

set

public final void set(int index,
 JavaScriptObject value)

Sets the object 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 object.

Parameters:

index - the index to be set

value - the JavaScriptObject to be stored

set

public final void set(int index,
 String value)

Sets the String 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 String.

Parameters:

index - the index to be set

value - the String to be stored

setLength

public final void setLength(int newLength)

Reset the length of the array.

Parameters:

newLength - the new length of the array

shiftBoolean

public final boolean shiftBoolean()

Shifts the first value off the array.

Returns:

the shifted item coerced to a boolean

shiftNumber

public final double shiftNumber()

Shifts the first value off the array.

Returns:

the shifted item coerced to a number

shiftObject

public final <T extends JavaScriptObject> T shiftObject()

Shifts the first value off the array.

Returns:

the shifted JavaScriptObject

shiftString

public final String shiftString()

Shifts the first value off the array.

Returns:

the shifted String

unshift

public final void unshift(boolean value)

Shifts a boolean onto the beginning of the array.

Parameters:

value - the value to the stored

unshift

public final void unshift(double value)

Shifts a double onto the beginning of the array.

Parameters:

value - the value to store

unshift

public final void unshift(JavaScriptObject value)

Shifts a JavaScriptObject onto the beginning of the array.

Parameters:

value - the value to store

unshift

public final void unshift(String value)

Shifts a String onto the beginning of the array.

Parameters:

value - the value to store
