Public Methods

Method

public void clearTileCache()

Clears the cache of a tile overlay.

Parameters:
None.
Return:
None.

Method

public boolean equals(Object other)

Checks whether a tile overlay object equals another.

Parameters:

Parameter name	Parameter desc
other	Name of another tile overlay object.

Return:

Return type	Parameter desc
boolean	If the tile overlay objects are equal, true is returned. Otherwise, false is returned.

Method

public boolean getFadeIn()

Checks whether a tile overlay fades in.

Parameters:
None.
Return:

Return type	Parameter desc
boolean	Whether a tile overlay fades in.

Method

public String getId()

Return type	Parameter desc
String	ID of a tile overlay.

Method

public float getTransparency()

Obtains the transparency of a tile overlay.

Parameters:
None.
Return:

Return type	Parameter desc
float	Transparency of a tile overlay. The value ranges from 0 (completely opaque) to 1 (completely transparent).

Method

public float getZIndex()

Obtains the z-index of a tile overlay.

Parameters:
None.
Return:

Return type	Parameter desc
float	Z-index, which indicates the overlapping order of a tile overlay.

Method

public int hashCode()

Obtains the hash code of a tile overlay.

Parameters:
None.
Return:

Return type	Parameter desc
int	Hash code of a tile overlay.

Method

public boolean isVisible()

Checks whether a tile overlay is visible.

Parameters:
None.
Return:

Return type	Parameter desc
boolean	If a tile overlay is visible, true is returned. Otherwise, false is returned.

Method

public void remove()

Removes a tile overlay from a map.

Parameters:
None.
Return:
None.

Method

public void setFadeIn(boolean fadeIn)

Specifies whether to make a tile overlay fade in.

Parameters:

Parameter name	Parameter desc
fadeIn	Indicates whether to make a tile overlay fade in.

Return:
None.

Method

public void setTransparency(float transparency)

Sets the transparency of a tile overlay.

Parameters:

Parameter name	Parameter desc
transparency	Transparency of a tile overlay. The value ranges from 0 (completely opaque) to 1 (completely transparent).

Return:
None.

Method

public void setVisible(boolean visible)

Specifies whether a tile overlay is visible. If the tile overlay is invisible, it will not be drawn but all other states will be preserved. By default, a tile overlay is visible.

Parameters:

Parameter name	Parameter desc
visible	If a tile overlay is visible, true is returned. Otherwise, false is returned.

Return:
None.

Method

public void setZIndex(float zIndex)

Sets the z-index of a tile overlay. The z-index indicates the overlapping order of a tile overlay. A tile overlay with a larger z-index overlaps that with a smaller z-index. Tile overlays with the same z-index overlap each other in a random order. By default, the z-index is 0.

Parameters:

Parameter name	Parameter desc
zIndex	Z-index, which indicates the overlapping order of a tile overlay.

Return:
None.
