Class StateController

java.lang.Object

com.alexvasilkov.gestures.StateController

public class StateController
extends java.lang.Object

Helper class that holds reference to Settings object and controls some aspects of view State, such as movement bounds restrictions (see getMovementArea(State, RectF)) and dynamic min / max zoom levels (see getMinZoom(State) and getMaxZoom(State)).

Method Detail

setTempZoomPatch

public void setTempZoomPatch(float factor)

applyZoomPatch

public void applyZoomPatch(State state)

applyZoomPatch

public float applyZoomPatch(float zoom)

getMinZoom

public float getMinZoom(State state)

Parameters:

state - Current state

Returns:

Min zoom level as it's used by state controller.

getMaxZoom

public float getMaxZoom(State state)

Parameters:

state - Current state

Returns:

Max zoom level as it's used by state controller. Note, that it may be different from Settings.getMaxZoom().

getMovementArea

public void getMovementArea(State state,
                            android.graphics.RectF out)

Calculates area in which State.getX() & State.getY() values can change. Note, that this is different from Settings.setMovementArea(int, int) which defines part of the viewport in which image can move.

Parameters:

state - Current state

out - Output movement area rectangle

getEffectiveMinZoom

@Deprecated
public float getEffectiveMinZoom()

Deprecated. Use getMinZoom(State) instead.

Returns:

Min zoom level

getEffectiveMaxZoom

@Deprecated
public float getEffectiveMaxZoom()

Deprecated. Use getMaxZoom(State) instead.

Returns:

Max zoom level

getEffectiveMovementArea

@Deprecated
public void getEffectiveMovementArea(android.graphics.RectF out,
                                                 State state)

Deprecated. User getMovementArea(State, RectF) instead.

Parameters:

out - Output movement area rectangle

state - Current state

restrict

@Deprecated
public static float restrict(float value,
                                         float minValue,
                                         float maxValue)

Deprecated. Use MathUtils.restrict(float, float, float).

Parameters:

value - Value to be restricted

minValue - Min value

maxValue - Max value

Returns:

Restricted value

interpolate
