public interface Interpreter
Represents an interpter that can interpret the scripting codes.
It is easier to implement by extending
from GenericInterpreter
.

void init(Page owner, java.lang.String zslang)
zslang
- the language this interpreter is associated withvoid destroy()
Page getOwner()
java.lang.String getLanguage()
java.lang.Object getNativeInterpreter()
void interpret(java.lang.String script, Namespace ns)
interpret(String, Scope)
Evaluates the script against the specified namespace.
void interpret(java.lang.String script, Scope scope)
Implementation Note:
LanguageDefinition.getEachTimeScript(java.lang.String)
if not null.Scopes.getCurrent(org.zkoss.zk.ui.Page)
to retrieve the current namesace if the comp argument is null.
scope
- the scope as the context to interpret the script.
If null, the current scope is assumed.
The current scope is Scopes.getCurrent(org.zkoss.zk.ui.Page)
, which
is the event target's scope, if the thread is processing an event.
The event target is Event.getTarget()
.
Otherwise, the current scope is the owner page (getOwner()
.java.lang.Class getClass(java.lang.String clsnm)
Function getFunction(java.lang.String name, java.lang.Class[] argTypes)
argTypes
- the list of argument (aka., parameter) types.
If null, Class[0] is assumed.boolean containsVariable(java.lang.String name)
Scope
).
java.lang.Object getVariable(java.lang.String name)
Scope
).
void setVariable(java.lang.String name, java.lang.Object value)
Note: it is not part of any namespace and it has higher prioerty if its name conflicts with any variable defined in the namespaces.
void unsetVariable(java.lang.String name)
