java.lang.Enum<LabelLineConnection>

com.esri.arcgisruntime.mapping.labeling.LabelLineConnection

All Implemented Interfaces:

Serializable, Comparable<LabelLineConnection>

public enum LabelLineConnection
extends Enum<LabelLineConnection>

The strategy for whether line features with the same label, and matching end vertices, should be joined before sharing a label.

Since:

100.11.0

Enum Constant Summary

Enum Constants

Enum Constant	Description
AUTOMATIC	The default approach for connectable features is to connect them (MINIMIZE_LABELS).
MINIMIZE_LABELS	Line geometries with the same label and coincident end vertices should be considered together as a single, continuous geometry when placing labels.
NONE	Keep one label per line feature geometry.
UNAMBIGUOUS_LABELS	Line geometries with the same label and coincident end vertices should be joined, until they hit a junction.

Method Summary

Modifier and Type	Method	Description
static LabelLineConnection	valueOf(String name)	Returns the enum constant of this type with the specified name.
static LabelLineConnection[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

AUTOMATIC

public static final LabelLineConnection AUTOMATIC

The default approach for connectable features is to connect them (MINIMIZE_LABELS).

This value corresponds to no value being specified for a LabelDefinition.getLineConnection() property.

Since:

100.11.0

MINIMIZE_LABELS

public static final LabelLineConnection MINIMIZE_LABELS

Line geometries with the same label and coincident end vertices should be considered together as a single, continuous geometry when placing labels.

For example, if a single label is being placed on a line feature, then the single location will be chosen along the combined geometries. This combining will ignore junctions, so it may be ambiguous which line feature after a junction is the continuation of the earlier geometry.

Since:

100.11.0

NONE

public static final LabelLineConnection NONE

Keep one label per line feature geometry.

Since:

100.11.0

UNAMBIGUOUS_LABELS

public static final LabelLineConnection UNAMBIGUOUS_LABELS

Line geometries with the same label and coincident end vertices should be joined, until they hit a junction.

For example, if a single label is being placed on a line geometry (composed of multiple features' geometries, but all having the same label text), then a label will be placed on both sides of any junction, to make it unambiguous which geometries are the continuation of the initial geometry.

Since:

100.11.0

Method Detail

values

public static LabelLineConnection[] 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 (LabelLineConnection c : LabelLineConnection.values())
    System.out.println(c);

Returns:

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

valueOf

public static LabelLineConnection 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
