Method Details

getTypes

public Set<Class<?>> getTypes()

Description copied from interface: VariableInterceptor

Returns the set of variable value types that this interceptor can handle.

Use Camunda's existing type interfaces like: - PrimitiveValue.class for primitive variables - DateValue.class for date variables - ObjectValue.class for object variables (JSON, XML, Java serialized) - FileValue.class for file variables - SpinValue.class for Spin variables

If the returned set is empty, this interceptor will be called for all variable types.

Default implementation returns an empty set (handle all types) for backward compatibility.

Specified by:

getTypes in interface VariableInterceptor

Returns:

set of supported variable value types, or empty set to handle all types

execute

public void execute(VariableInvocation invocation)

Description copied from interface: VariableInterceptor

Executes the interceptor logic for a variable invocation. This method will only be called if the variable type matches one of the supported types.

Specified by:

execute in interface VariableInterceptor

Parameters:

invocation - the variable invocation containing C7 variable data and methods to modify it

setJsonVariable

protected void setJsonVariable(VariableInvocation invocation,
 String jsonString)
