Interface IContextProvider

All Known Implementing Classes:

DefaultContextProvider

public interface IContextProvider

A context provider is responsible for providing the correct context whenever lines in a patch are filtered. This becomes necessary, because filtering changes from a patch results in a new context for adjacent changes that have not been filtered.

Method Summary

Modifier and Type	Method	Description
List<Line>	leadingContext(ILineFilter lineFilter, FileDiff fileDiff, int index)	Determine the lines in the leading context of a change and return them.
List<Line>	trailingContext(ILineFilter lineFilter, FileDiff fileDiff, int index)	Determine the lines in the trailing context of a change and return them.

Method Details

leadingContext

List<Line> leadingContext(ILineFilter lineFilter,
 FileDiff fileDiff,
 int index)

Determine the lines in the leading context of a change and return them. The context is determined based on a provided filter that may remove lines from the context.

Parameters:

lineFilter - The line filter that has been used to adjust the patch for which the context is provided

fileDiff - The file diff containing the hunks for which a new context is to be determined

index - The line number of the change for which a context is to be provided

Returns:

The leading context for the change

trailingContext

List<Line> trailingContext(ILineFilter lineFilter,
 FileDiff fileDiff,
 int index)

Determine the lines in the trailing context of a change and return them. The context is determined based on a provided filter that may remove lines from the context.

Parameters:

lineFilter - The line filter that has been used to adjust the patch for which the context is provided

fileDiff - The file diff containing the hunks for which a new context is to be determined

index - The line number of the change for which a context is to be provided

Returns:

The trailing context for the change
