SourceLocation

data class SourceLocation
kotlin.Any
   ↳ androidx.ui.tooling.SourceLocation

Source location of the call that produced the call group.

Summary

Public constructors
<init>(lineNumber: Int, offset: Int, length: Int, sourceFile: String?, packageHash: Int)

Source location of the call that produced the call group.

Properties
Int

The length of the source code.

Int

A 0 offset line number of the source location.

Int

Offset into the file.

Int

A hash code of the package name of the file.

String?

The file name (without path information) of the source file that contains the call that produced the group.

Public constructors

<init>

SourceLocation(
    lineNumber: Int,
    offset: Int,
    length: Int,
    sourceFile: String?,
    packageHash: Int)

Source location of the call that produced the call group.

Properties

length

val length: Int

The length of the source code. The length is calculated as the number of UTF-16 code units that that make up the call expression.

lineNumber

val lineNumber: Int

A 0 offset line number of the source location.

offset

val offset: Int

Offset into the file. The offset is calculated as the number of UTF-16 code units from the beginning of the file to the first UTF-16 code unit of the call that produced the group.

packageHash

val packageHash: Int

A hash code of the package name of the file. This hash is calculated by,

packageName.fold(0) { hash, current -> hash * 31 + current.toInt() }?.absoluteValue

where the package name is the dotted name of the package. This can be used to disambiguate which file is referenced by sourceFile. This number is -1 if there was no package hash information generated such as when the file does not contain a package declaration.

sourceFile

val sourceFile: String?

The file name (without path information) of the source file that contains the call that produced the group. A source file names are not guaranteed to be unique, packageHash is included to help disambiguate files with duplicate names.
