Method Detail

toCallable

public Callable toCallable(Env env)

Description copied from class: Value

Converts to a callable

Overrides:

toCallable in class Value

callArray

public final Value callArray(Env env,
                             ArrayValue array,
                             Value key,
                             Value a1)

Evaluates a callback where the first argument is from an array. The callback may be modifying that array element. For ArrayModule.

Specified by:

callArray in interface Callable

Parameters:

env -

array - from which a1 came from

key - index of a1 in the array

a1 - need to make a reference to this variable

callArray

public final Value callArray(Env env,
                             ArrayValue array,
                             Value key,
                             Value a1,
                             Value a2)

Evaluates a callback where the first argument is from an array. The callback may be modifying that array element. For ArrayModule.

Specified by:

callArray in interface Callable

Parameters:

env -

array - from which a1 came from

key - index of a1 in the array

a1 - need to make a reference to this variable

a2 - additional argument to pass to the callback

callArray

public final Value callArray(Env env,
                             ArrayValue array,
                             Value key,
                             Value a1,
                             Value a2,
                             Value a3)

Evaluates a callback where the first argument is from an array. The callback may be modifying that array element. For ArrayModule.

Specified by:

callArray in interface Callable

Parameters:

env -

array - from which a1 came from

key - index of a1 in the array

a1 - need to make a reference to this variable

a2 - additional argument to pass to the callback

a3 - additional argument to pass to the callback

call

public abstract Value call(Env env,
                           Value[] args)

Evaluates the callback with variable arguments.

Specified by:

call in interface Callable

Overrides:

call in class Value

Parameters:

env - the calling environment

isValid

public abstract boolean isValid(Env env)

Description copied from interface: Callable

Checks for a valid callback.

Specified by:

isValid in interface Callable

Returns:

true if this is an invalid callback reference

public abstract java.lang.String getCallbackName()

Returns the name of the callback.

Specified by:

getCallbackName in interface Callable

isInternal

public abstract boolean isInternal(Env env)

Returns true if this callback is implemented internally (i.e. in Java).

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
