Constructor Detail

V8Value

protected V8Value(V8Runtime v8Runtime)
           throws JavetException

Instantiates a new V8 value associated with the given runtime.

Parameters:

v8Runtime - the V8 runtime

Throws:

JavetException - if the runtime is null

Method Detail

checkV8Runtime

protected V8Runtime checkV8Runtime()
                            throws JavetException
