DataType.setAsBoolean() 241

Returns

An array of strings describing any errors that occurred while attempting to set the new value.

Errors can occur under any of the following conditions:

■ The data provided cannot be converted to the data type of this field (for example, "abc"

cannot be converted to Number).

■ The data is an acceptable type but does not meet the validation criteria of the field.

■ The field is read-only.

Description

Method; sets a new value in the field, using the information in the field’s schema to process

the field.

This method operates by first calling

DataType.setTypedValue() to set the value. If that

fails, the method checks to see if the destination object is willing to accept String, Boolean, or

Number data, and if so, attempts to use the corresponding ActionScript conversion functions.

Example

The following example creates a new TypedValue object (a Boolean value), and then assigns

that value to a DataType object named

field. Any errors that occur are assigned to the

errors array.

import mx.data.binding.*;

var t:TypedValue = new TypedValue (true, "Boolean");

var errors: Array = field.setAnyTypedValue (t);
