Name
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)>Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
