Method Detail

setServices

public void setServices(Map<String,Object> services)

complete

public int complete(String s,
                    int i,
                    List list)

Specified by:

complete in interface jline.Completor

contextComplete

public int contextComplete(Object baseObject,
                           String s,
                           int i,
                           List<String> list)

Base Object can be an object where we're looking for methods on it, or an interface. This recursively works off the completions left to right. Objects can be completed with fields or method calls. method parameters are completed with type matching method result chainings are completed based on declared return types e.g. have a Resource in context as myResource. Original string is "myResource.name". This method would be called with a baseObject == to myResource and the string "name". Note: this method will not and should not execute methods, but will read field properties to continue chained completions.

Parameters:

baseObject - the context object or class to complete from

s - the relative command string to check

i -

list -

Returns:

location of relative completion

completeParameters

public int completeParameters(Object baseObject,
                              String params,
                              int i,
                              List<String> list,
                              Method method)

Split apart the parameters to a method call and complete the last parameter. If the last paramater has a valid value close that field with a "," for the next param or a ")" if is the last parameter. Does all machting according to the type of the parameters of the supplied method.

Parameters:

baseObject -

params -

i -

list -

method -

Returns:

getContext

public ScriptContext getContext()

setContext

public void setContext(ScriptContext context)
