Method Detail

toJsArrayNumber

public static com.google.gwt.core.client.JsArrayNumber toJsArrayNumber(double... array)

Converts from a Java array to a JavaScript array.

Parameters:

array - the Java array to convert from.

Returns:

the equivalent JavaScript array.

toJsArrayNumberFromDouble

public static com.google.gwt.core.client.JsArrayNumber toJsArrayNumberFromDouble(double... array)

Converts from a Java array to a JavaScript array.

Parameters:

array - the Java array to convert from.

Returns:

the equivalent JavaScript array.

toJsArrayInteger

public static com.google.gwt.core.client.JsArrayInteger toJsArrayInteger(int... array)

Converts from a Java array to a JavaScript array.

Parameters:

array - the Java array to convert from.

Returns:

the equivalent JavaScript array.

unwrapArray

public static java.lang.String[] unwrapArray(com.google.gwt.core.client.JsArrayString jsArrayString)

Converts a JsArrayString to a String[].

Parameters:

jsArrayString - the array to unwrap.

Returns:

the created String[].

wrapArray

public static com.google.gwt.core.client.JsArrayBoolean wrapArray(boolean[] srcArray)

Wraps a Java boolean Array to a JsArrayBoolean.

Parameters:

srcArray - the array to wrap

Returns:

the wrapped array

wrapArray

public static com.google.gwt.core.client.JsArrayInteger wrapArray(byte[] srcArray)

Wraps a Java byte Array to a JsArrayInteger.

Parameters:

srcArray - the array to wrap

Returns:

the wrapped array

wrapArray

public static com.google.gwt.core.client.JsArrayInteger wrapArray(short[] srcArray)

Wraps a Java byte Array to a JsArrayInteger.

Parameters:

srcArray - the array to wrap

Returns:

the wrapped array

wrapArray

public static com.google.gwt.core.client.JsArrayNumber wrapArray(double[] srcArray)

Wraps a Java double Array to a JsArrayNumber.

Parameters:

srcArray - the array to wrap

Returns:

the wrapped array

wrapArray

public static com.google.gwt.core.client.JsArrayInteger wrapArray(int[] srcArray)

Wraps a Java int Array to a JsArrayInteger.

Parameters:

srcArray - the array to wrap

Returns:

the wrapped array

wrapArray

public static com.google.gwt.core.client.JsArrayInteger wrapArray(long[] srcArray)

Wraps a Java long Array to a JsArrayInteger. Pay attention: Avoid using long values in GWT if possible ( "http://code.google.com/intl/de-DE/webtoolkit/doc/latest/DevGuideCodingBasicsCompatibility.html#language" ). This method has poor performance in production mode compared with the int[] version ( wrapArray(int[])). Please note that in production mode int, short and byte are handled as 64Bit floating point values, so you can use them for values >2^31-1. Keep in mind that not every long value can be represented exactly by 64Bit floating values. Be aware that this won't work correctly in dev mode and no literals above that limit are supported in Java.

Parameters:

srcArray - the array to wrap

Returns:

the wrapped array

wrapArray

public static com.google.gwt.core.client.JsArrayString wrapArray(java.lang.String[] srcArray)

Wraps a Java String Array to a JsArrayString.

Parameters:

srcArray - the array to wrap

Returns:

the wrapped array
