When using sumo for simulation experiment, I need to add my own parameters to the vehicle.There are Vehicle Type Parameter Defaults such as width and length.But how can i customize the parameter i want to the vehicle and get the parameter through a function.
You can set and retrieve arbitrary parameters for vehicles (and even for edges, POIs and other elements). In the XML input you would use the syntax
<vehicle id=...>
<param key="foo" value="bar"/>
</vehicle>
For traci and libsumo there are getParameter / setParameter functions.

I want to drive the ouput values of custom attributes of a expression node by variables inside this same expression node.
Expressions do not work like this. You cannot assing a value to an attribute this way. The direct assingment only works if you set an value of a connected destination. If you want to set an attribute, you have to use setAttr().
How can I pass additional arguments from the List component to the dataProvider I am building?
For example:
<List filter={myFilters} perPage={10} myArgs={someArgs} {...props} >
I do receive the filter argument, but I don't receive myArgs.
You can't. dataProvider.getList() only accepts filter, sort, and pagination parameters (see documentation).
You can add code in your dataProvider to transform a specific filter into a special argument, or use another resource name that triggers a special piece of logic.
But the question is: why do you need to pass additional parameters for?
I am trying to create a custom inspection in IntelliJ using structural search. The idea is to find all methods that have one or more parameters, of which at least one is not annotated. Bonus: Only hit non-primitive types of parameters.
So far, I have created the following Search Template:
$MethodType$ $Method$(#$ParamAnnotation$ $ParameterType$ $Parameter$);
using these filters and the search target "complete match":
$Parameters$: count[1,∞]
$ParamAnnotation$: count[0,0]
However, this only hits methods without any parameters annotated. I want it to also match methods where only some parameters have an annotation but others don't.
Is it possible to reference the count of one variable in the filter of another, e.g. by using script filters? If so, how?
You can do this by creating a Search Template like this:
$MethodType$ $Method$($TypeBefore$ $before$,
#$ParamAnnotation$ $ParameterType$ $Parameter$,
$TypeAfter$ $after$);
Filters:
$Parameters$: count=[1,1] // i.e. no filter
$ParamAnnotation$: count=[0,0]
$before$: count=[0,∞]
$after$: count=[0,∞]
This will find all method with at least one parameter without annotation.
PARAMETERS p_var LIKE varit-variant.
The LIKE varit-variant addition assists the user with the inclusion of a search help, where a user may enter a report name, and it lists the variants from the VARIT table and feeds them to the user.
However, ABAP best practice prohibits using LIKE when referring to DDIC types. How can one retain this functionality without using obsolete language elements?
You can just use type:
PARAMETERS: p_var type varit-variant.
You can also use the below code, if you want to use specific search help.
PARAMETERS: p_var TYPE variant MATCHCODE OBJECT h_varid.
in this example: h_varid is a search help name.
How can i set current date using expression builder in oracle adf?
i am using jdeveloper 11.1.1.3.0 and using Input Date(ADF faces.common.component)
The expression builder is used to build EL expressions that reference a method or a value property. Its not meant to set a value but to make it available for editing. One option would be to use a method expression to invoke an action on a manage bean that then sets the value. However, in JSF 1.2 you cannot pass arguments to an EL method and for this reason you would need a work around for setting a date. The work around is that the method expression (and thus the press of a button) invokes a method, which then creates the current date (or whatever date you want to pass in) and sets it on the component directly (though setting it on the component model works much better IMO).

Another option is to have your datasource field have a default value defined for it in the business service layer. So for example if you are using ADF BC then your field can have a default of adf.currentDate.
