接口 TokenOrientedView

所有已知实现类:

SyntaxView

public interface TokenOrientedView

An interface for the syntax-highlighting token oriented views for token-oriented methods. This way callers won't need to know what specific class a view is an instance of to access its tokens.

Currently, this interface is only useful for obtaining token lists for "physical lines" (i.e., a word-wrapped view's logical lines may be represented as several physical lines, thus getting the "physical line" above a given position may prove complicated).

方法详细资料

getTokenListForPhysicalLineAbove

Token getTokenListForPhysicalLineAbove(int offset)

Returns a token list for the physical line above the physical line containing the specified offset into the document. Note that for a plain (non-wrapped) view, this is simply the token list for the logical line above the line containing offset, since lines are not wrapped. For a wrapped view, this may or may not be tokens from the same line.

参数:

offset - The offset in question.

返回:

A token list for the physical (and in this view, logical) line before this one. If no physical line is above the one containing offset, null is returned.

getTokenListForPhysicalLineBelow

Token getTokenListForPhysicalLineBelow(int offset)

Returns a token list for the physical line below the physical line containing the specified offset into the document. Note that for a plain (non-wrapped) view, this is simply the token list for the logical line below the line containing offset, since lines are not wrapped. For a wrapped view, this may or may not be tokens from the same line.

参数:

offset - The offset in question.

返回:

A token list for the physical (and in this view, logical) line after this one. If no physical line is after the one containing offset, null is returned.
