EMPTY

static final ScriptHostFunctionResolver EMPTY

A host function resolver with no functions or namespaces.

1.8.0

Method Details

containsNamespacedFunction

boolean containsNamespacedFunction(String namespace,
 String name)

Attempts to find if this resolver has a function by its calling name and namespace.

A null namespace is valid, since it is a host call without declaring a namespace.

Names must be resolved case-insensitively!

If this returns true for a function name, getNamespacedFunction(String, String) must NOT return null if called with that name!

Parameters:

namespace - the function namespace (null is valid!).

name - the name to find.

Returns:

a corresponding function or null for no such function.

getNamespacedFunction

ScriptFunctionType getNamespacedFunction(String namespace,
 String name)

Attempts to resolve a pertinent function by its calling name.

A null namespace is valid, since it is a host call without declaring a namespace.

Names must be resolved case-insensitively!

If this returns a non-null for a function name, containsNamespacedFunction(String, String) must NOT return false if called with that name!

The same function must be returned if this is called again with the same name!

Parameters:

namespace - the function namespace (null is valid!).

name - the name to resolve.

Returns:

a corresponding function or null for no such function.
