JavaCast — New as of ColdFusion 4.5

Synopsis

JavaCast(type, variable)

Casts a ColdFusion variable before being passed to an overloaded Java method. Possible entries for type include bool, int, long, double, or string. The JavaCast( ) function can’t cast complex objects, such as query objects, arrays, and structures, nor can it cast to a super-class. The following example demonstrates how to explicitly cast a ColdFusion variable before passing it to an overloaded method within a Java object:

<CFOBJECT TYPE="Java" ACTION="Create" CLASS="MyClass" NAME="MyObject">

<CFSET x=10>          

<!--- cast x to a string --->
<CFSET MyString = JavaCast("string",x)>
<CFSET void = MyMethod(MyString)>

<!--- cast x to an integer --->
<CFSET MyInteger = JavaCast("int",x)>
<CFSET void = MyMethod(MyInteger)>
