Methods

addChild(child) → {this}

Description:

  • Add a child (or an array of children) to the object.

Source:
Inherited From:
Parameters:
Name Type Description
child geo.object | Array.<geo.object>

A child object or array of child objects.
Returns:
Type
this

addPromise(promise) → {this}

Description:

  • Add the promise here and also propagate up the scene tree.

Source:
Inherited From:
Parameters:
Name Type Description
promise Promise

A promise object.
Returns:
Type
this

bin(valopt, actualValueopt) → {number|this}

Description:

  • Get/Set bin of the feature. The bin number is used to determine the order of multiple features on the same layer. It has no effect except on the webgl renderer. A negative value hides the feature without stopping interaction with it. Otherwise, features with higher bin numbers are drawn above those with lower bin numbers. If two features have the same bin number, their order relative to one another is indeterminate and may be unstable.

Source:
Parameters:
Name Type Attributes Description
val number <optional>

The new bin number. If undefined, return the current bin number. If null, the bin is dynamically computed based on order within the parent. If children are nested, this may not be what is desired.
actualValue boolean <optional>

If truthy and val is undefined, return the actual value of bin, rather than the dynamically computed value.
Returns:

The current bin number or a reference to this.

Type
number | this
