Slot Details

disOf

Str? disOf(Col col)

Get display string for the given column, if value is null then return null. If the column meta defines a "format"* pattern, then it is used to format the value via the appropiate toLocale method.

each

virtual override Void each(|Obj,Str| f)

Iterate through all the columns.

eachWhile

virtual override Obj? eachWhile(|Obj,Str->Obj?| f)

Iterate through all the columns until function returns null, then break iteration and return the result.

get

@Operator virtual override Obj? get(Str name)

Get the column val by name or null

grid

abstract Grid grid()

Parent grid

has

virtual override Bool has(Str name)

Return true if the given name is mapped to a non-null column val.

isEmpty

virtual override Bool isEmpty()

Always returns false.

missing

virtual override Bool missing(Str name)

Return true if the given name is not mapped to a non-null column val.

trap

virtual override Obj? trap(Str name, Obj?[]? args := null)

Get the column val by name. If column name doesn't exist or if the column value is null, then throw UnknownNameErr.

val

abstract Obj? val(Col col)

Scalar value for the cell
