Interface UITextInputTokenizer

All Known Implementing Classes:

UITextInputStringTokenizer

public interface UITextInputTokenizer

A tokenizer allows the text input system to evaluate text units of varying granularity.

Method Summary

Modifier and Type	Method and Description
boolean	isPositionAtBoundaryInDirection(UITextPosition position, long granularity, long direction) Returns YES only if a position is at a boundary of a text unit of the specified granularity in the particular direction.
boolean	isPositionWithinTextUnitInDirection(UITextPosition position, long granularity, long direction) Returns YES if position is within a text unit of the given granularity.
UITextPosition	positionFromPositionToBoundaryInDirection(UITextPosition position, long granularity, long direction) Returns the next boundary position of a text unit of the given granularity in the given direction, or nil if there is no such position.
UITextRange	rangeEnclosingPositionWithGranularityInDirection(UITextPosition position, long granularity, long direction) Returns range of the enclosing text unit of the given granularity, or nil if there is no such enclosing unit.

Method Detail

isPositionAtBoundaryInDirection

boolean isPositionAtBoundaryInDirection(UITextPosition position,
                                        long granularity,
                                        long direction)

Returns YES only if a position is at a boundary of a text unit of the specified granularity in the particular direction.

isPositionWithinTextUnitInDirection

boolean isPositionWithinTextUnitInDirection(UITextPosition position,
                                            long granularity,
                                            long direction)

Returns YES if position is within a text unit of the given granularity. If the position is at a boundary, returns YES only if the boundary is part of the text unit in the given direction.

positionFromPositionToBoundaryInDirection

UITextPosition positionFromPositionToBoundaryInDirection(UITextPosition position,
                                                         long granularity,
                                                         long direction)

Returns the next boundary position of a text unit of the given granularity in the given direction, or nil if there is no such position.

rangeEnclosingPositionWithGranularityInDirection

UITextRange rangeEnclosingPositionWithGranularityInDirection(UITextPosition position,
                                                             long granularity,
                                                             long direction)

Returns range of the enclosing text unit of the given granularity, or nil if there is no such enclosing unit. Whether a boundary position is enclosed depends on the given direction, using the same rule as isPosition:withinTextUnit:inDirection:
