Class ParametersCallbackMap

java.lang.Object

scriptella.driver.script.ParametersCallbackMap

All Implemented Interfaces:

Map<String,Object>, ParametersCallback

Direct Known Subclasses:

BindingsParametersCallback

public class ParametersCallbackMap
extends Object
implements ParametersCallback, Map<String,Object>

Map implementation of ParametersCallback for integration into Scriptella execution environment.

This class allows local variables to be set via put(String,Object) method.
getParameter(String) allows reading variables.

In query mode, a virtual variable query is available and exposes a method next() to populate result set.

Note: current implementation does not distinguish if a variable is absent or has a value of null.

Method Details

getParameter

public Object getParameter(String name)

Returns specified variable value.

The local variables set by put(String,Object) method take priority of variables in parentParameters object.

Specified by:

getParameter in interface ParametersCallback

Parameters:

name - variable name

Returns:

value of variable or null if variable not found.

get

public Object get(Object key)

Use getParameter(String).

Specified by:

get in interface Map<String,Object>

Parameters:

key - variable name.

Returns:

value of variable.

containsKey

public boolean containsKey(Object key)

Specified by:

containsKey in interface Map<String,Object>

put

public Object put(String key,
 Object value)

Sets local variable.

Specified by:

put in interface Map<String,Object>

Parameters:

key - variable name.

value - variable value.

Returns:

previous variable value.

remove

public Object remove(Object key)

Removes local variable.

Specified by:

remove in interface Map<String,Object>

Parameters:

key - variable name.

Returns:

previous value.

putAll

public void putAll(Map<? extends String,?> t)

Registers local variables.

Specified by:

putAll in interface Map<String,Object>

Parameters:

t - local variables map.

clear

public void clear()

Clears local variables.

Specified by:

clear in interface Map<String,Object>

Parameters:

queryCallback - query callback.

next

public void next()

Executes nested elements and exposes local variables set by the current query.

isNextCalled

public boolean isNextCalled()

CRQ-12257. Returns true if next was called on this query.

Returns:

true if next was called on this query.
