Class StructuredLineNumberInfo

java.lang.Object

proguard.classfile.attribute.LineNumberInfo

proguard.classfile.attribute.StructuredLineNumberInfo

public class StructuredLineNumberInfo
extends LineNumberInfo

Line number info with extra information for lines that came from a different source than the current method (e.g. inlined from a different method). Tracking this information is necessary for printing a correct mapping file.

The structured line number info contains:

• Source string indicating the originating class/method of the line.
• Optional start/end line number indicating the original line numbers for a block of inlined instructions.
• A list of origins, indicating the transformations these lines underwent, e.g. multiple levels of inlining
• A block ID, that identifies a group of lines that belongs to a singular block.

Since these transformations operate on blocks of lines, and the mapping file identifies blocks rather than singular lines, StructuredLineNumberInfo objects are generated through a StructuredLineNumberInfo.Block object, which is a factory object that generates StructuredLineNumberInfos with consistent block IDs.

Method Details

getSourceMethod

public String getSourceMethod()

Overrides:

getSourceMethod in class LineNumberInfo

getSourceLineStart

public int getSourceLineStart()

Overrides:

getSourceLineStart in class LineNumberInfo

getSourceLineEnd

public int getSourceLineEnd()

Overrides:

getSourceLineEnd in class LineNumberInfo

getBlockId

public int getBlockId()

Get the block ID which identifies related line numbers which form a single block in the mapping file.

Overrides:

getBlockId in class LineNumberInfo

getOrigin

public List<LineOrigin> getOrigin()

Get a chronological list of manipulations that this line went through. True origin is the first element, followed by any subsequent manipulations (e.g. multiple levels of inlining, copying, etc.).

Overrides:

getOrigin in class LineNumberInfo

getSource

public String getSource()

Description copied from class: LineNumberInfo

Returns a description of the source of the line, if known, or null otherwise. Standard line number entries don't contain information about their source; it is assumed to be the same source file.

Overrides:

getSource in class LineNumberInfo

getBlock

public LineNumberInfoBlock getBlock()

Overrides:

getBlock in class LineNumberInfo

getBlock

public StructuredLineNumberInfo.Block getBlock(LineOrigin... addedOrigins)
