Enum OverlapBehavior

Object

Enum<OverlapBehavior>

OverlapBehavior

All Implemented Interfaces:

Serializable, Comparable<OverlapBehavior>

@XmlElement(value="OverlapBehavior")
public enum OverlapBehavior
extends Enum<OverlapBehavior>

The OverlapBehavior element tells a system how to behave when multiple raster images in a layer overlap each other, for example with satellite-image scenes. LATEST_ON_TOP and EARLIEST_ON_TOP refer to the time the scene was captured. AVERAGE means to average multiple scenes together. This can produce blurry results if the source images are not perfectly aligned in their geo-referencing. RANDOM means to select an image (or piece thereof) randomly and place it on top. This can produce crisper results than AVERAGE potentially more efficiently than LATEST_ON_TOP or EARLIEST_ON_TOP. The default behaviour is system-dependent.

Since:

GeoAPI 2.2

Method Detail

values

public static OverlapBehavior[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (OverlapBehavior c : OverlapBehavior.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static OverlapBehavior valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
