Script class
A Script provides information about a Dart language script.
The tokenPosTable is an array of int arrays. Each subarray consists of a
line number followed by (tokenPos, columnNumber) pairs:
[lineNumber, (tokenPos, columnNumber)*]
The tokenPos is an arbitrary integer value that is used to represent a
location in the source code. A tokenPos value is not meaningful in itself
and code should not rely on the exact values returned.
For example, a tokenPosTable with the value...
[[1, 100, 5, 101, 8],[2, 102, 7]]
...encodes the mapping:
| tokenPos | line | column |
|---|---|---|
| 100 | 1 | 5 |
| 101 | 1 | 8 |
| 102 | 2 | 7 |
Constructors
Properties
- classRef ↔ ClassRef?
-
If an object is allocated in the Dart heap, it will have a corresponding
class object.
read / writeinherited
- columnOffset ↔ int?
-
read / write
- fixedId ↔ bool?
-
Provided and set to true if the id of an Object is fixed. If true, the id
of an Object is guaranteed not to change or expire. The object may,
however, still be Collected.
read / writeinherited
- hashCode → int
-
The hash code for this object.
read-onlyoverride
- id ↔ String?
-
A unique identifier for an Object. Passed to the getObject RPC to reload
this Object.
read / writeinherited
-
json
↔ Map<
String, dynamic> ? -
read / writeinherited
- library ↔ LibraryRef?
-
The library which owns this script.
read / write
- lineOffset ↔ int?
-
read / write
- runtimeType → Type
-
A representation of the runtime type of the object.
read-onlyinherited
- size ↔ int?
-
The size of this object in the heap.
read / writeinherited
- source ↔ String?
-
The source code for this script. This can be null for certain built-in
scripts.
read / write
-
tokenPosTable
↔ List<
List< ?int> > -
A table encoding a mapping from token position to line and column. This
field is null if sources aren't available.
read / write
- type → String
-
read-onlyoverride
- uri ↔ String?
-
The uri from which this script was loaded.
read / writeoverride
Methods
-
getColumnNumberFromTokenPos(
int tokenPos) → int? - This function maps a token position to a column number. The VM considers the first column to be column 1.
-
getLineNumberFromTokenPos(
int tokenPos) → int? - This function maps a token position to a line number. The VM considers the first line to be line 1.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toJson(
) → Map< String, dynamic> -
override
-
toString(
) → String -
A string representation of this object.
override
Operators
-
operator ==(
Object other) → bool -
The equality operator.
