This method converts the value passed in to an equivalent object in JavaScript before storing on the underlying data object - see JavaToJavaScriptConversion for details of the conversions that take place.
Developers can use setObjectAttribute(JavaScriptObject, String, Object) to store Java objects without converting to JavaScript.

Parameters:

elem - the JavaScriptObject on which to set the attribute

attr - the attribute name

value - the attribute value.

Returns attribute value set as a Boolean. For convenience in checking boolean properties, getAttributeAsBoolean will return Boolean false if the attribute value is null or not a Boolean. Use the three parameter variant of this API getAttributeAsBoolean(JavaScriptObject, String, boolean) if you want null returned for null attribute values.

Parameters:

elem - the JavaScriptObject containing the property

attr - the property name

Returns:

the property value

getAttributeAsBoolean

public static java.lang.Boolean getAttributeAsBoolean(com.google.gwt.core.client.JavaScriptObject elem,

                                                      boolean allowNull)

Returns attribute value set as a Boolean. If the attribute value is null or not a Boolean, the return value depends upon allowNull. If allowNull is true, null will be returned; otherwise Boolean false will be returned. For a simpler approach that never returns null, use the two parameter variant of this API getAttributeAsBoolean(JavaScriptObject, String).

Parameters:

elem - the JavaScriptObject containing the property

attr - the property name

allowNull - whether to permit a null return value

Returns:

the property value
