Method Detail

resolve

public org.mule.runtime.extension.api.runtime.operation.ParameterResolver<T> resolve(Event event)
                                                                              throws org.mule.runtime.api.exception.MuleException

Resolves a value from the given event

Specified by:

resolve in interface ValueResolver<org.mule.runtime.extension.api.runtime.operation.ParameterResolver<T>>

Parameters:

event - a Event

Returns:

a resolved value

Throws:

org.mule.runtime.api.exception.MuleException - if the resolution of the value fails

isDynamic

public boolean isDynamic()

returns false if subsequent invocations to ValueResolver.resolve(Event) will return the same value. Notice that if it returns true, then it might return different values per invocation but that's not guaranteed.

Specified by:

isDynamic in interface ValueResolver<org.mule.runtime.extension.api.runtime.operation.ParameterResolver<T>>

Returns:

whether this resolve is dynamic
