Interface DocSourcePositions

All Superinterfaces:
SourcePositions
public interface DocSourcePositions extends SourcePositions
Provides methods to obtain the position of a DocTree within a javadoc comment. A position is defined as a simple character offset from the start of a CompilationUnit where the first character is at offset 0.
Since:
1.8

Method Summary

Modifier and Type Method Description
long getEndPosition(DocCommentTree comment, DocTree tree)
Returns the ending position of the given Tree. If the ending position is not available, returns Diagnostic.NOPOS.
default long getEndPosition(CompilationUnitTree file, DocCommentTree comment, DocTree tree)
Deprecated, for removal: This API element is subject to removal in a future version.
use getEndPosition(DocCommentTree, DocTree) instead
long getStartPosition(DocCommentTree comment, DocTree tree)
Returns the starting position of the given Tree. If the starting position is not available, returns Diagnostic.NOPOS.
default long getStartPosition(CompilationUnitTree file, DocCommentTree comment, DocTree tree)
Deprecated, for removal: This API element is subject to removal in a future version.

Method Details

getStartPosition

@Deprecated(since="27", forRemoval=true) default long getStartPosition(CompilationUnitTree file, DocCommentTree comment, DocTree tree)
Deprecated, for removal: This API element is subject to removal in a future version.
use getStartPosition(DocCommentTree, DocTree) instead
Returns the starting position of the tree within the comment within the file. If tree is not found within file, or if the starting position is not available, returns Diagnostic.NOPOS. The given tree should be under the given comment tree, and the given documentation comment tree should be returned from a DocTrees.getDocCommentTree(com.sun.source.util.TreePath) for a tree under the given file. The returned position must be at the start of the yield of this tree, that is for any sub-tree of this tree, the following must hold:

getStartPosition(file, comment, tree) <= getStartPosition(file, comment, subtree) or
getStartPosition(file, comment, tree) == NOPOS or
getStartPosition(file, comment, subtree) == NOPOS

Parameters:
file - compilation unit in which to find tree
comment - the comment tree that encloses the tree for which the position is being sought
tree - tree for which a position is sought
Returns:
the start position of tree

getStartPosition

long getStartPosition(DocCommentTree comment, DocTree tree)
Returns the starting position of the given Tree. If the starting position is not available, returns Diagnostic.NOPOS.

The given tree should be under the given comment tree. The returned position must be at the start of the yield of this tree, that is for any sub-tree of this tree, the following must hold:

getStartPosition(comment, tree) <= getStartPosition(comment, subtree) or
getStartPosition(comment, tree) == NOPOS or
getStartPosition(comment, subtree) == NOPOS

Parameters:
comment - the comment tree that encloses the tree for which the position is being sought
tree - tree for which a position is sought
Returns:
the starting position of the given Tree. If the starting position is not available, returns Diagnostic.NOPOS
Since:
27

getEndPosition

@Deprecated(since="27", forRemoval=true) default long getEndPosition(CompilationUnitTree file, DocCommentTree comment, DocTree tree)
Deprecated, for removal: This API element is subject to removal in a future version.
use getEndPosition(DocCommentTree, DocTree) instead
Returns the ending position of the tree within the comment within the file. If tree is not found within file, or if the ending position is not available, returns Diagnostic.NOPOS. The given tree should be under the given comment tree, and the given documentation comment tree should be returned from a DocTrees.getDocCommentTree(com.sun.source.util.TreePath) for a tree under the given file. The returned position must be at the end of the yield of this tree, that is for any sub-tree of this tree, the following must hold:

getEndPosition(file, comment, tree) >= getEndPosition(file, comment, subtree) or
getEndPosition(file, comment, tree) == NOPOS or
getEndPosition(file, comment, subtree) == NOPOS

In addition, the following must hold:

getStartPosition(file, comment, tree) <= getEndPosition(file, comment, tree) or
getStartPosition(file, comment, tree) == NOPOS or
getEndPosition(file, comment, tree) == NOPOS

Parameters:
file - compilation unit in which to find tree
comment - the comment tree that encloses the tree for which the position is being sought
tree - tree for which a position is sought
Returns:
the end position of tree

getEndPosition

long getEndPosition(DocCommentTree comment, DocTree tree)
Returns the ending position of the given Tree. If the ending position is not available, returns Diagnostic.NOPOS.

The given tree should be under the given comment tree. The returned position must be at the end of the yield of this tree, that is for any sub-tree of this tree, the following must hold:

getEndPosition(comment, tree) >= getEndPosition(comment, subtree) or
getEndPosition(comment, tree) == NOPOS or
getEndPosition(comment, subtree) == NOPOS

In addition, the following must hold:

getStartPosition(comment, tree) <= getEndPosition(comment, tree) or
getStartPosition(comment, tree) == NOPOS or
getEndPosition(comment, tree) == NOPOS

Parameters:
comment - the comment tree that encloses the tree for which the position is being sought
tree - tree for which a position is sought
Returns:
the ending position of the given Tree. If the ending position is not available, returns Diagnostic.NOPOS
Since:
27
