Method Detail

isEquivalentTo

public boolean isEquivalentTo(Component other)

Description copied from class: Component

Compares this component to a different one to check if they are the same

This is used to be able to skip rendering a component again. We avoid using the Object.equals(Object) so we can optimize the code better over time since we don't have to adhere to the contract required for a equals method.

Specified by:

isEquivalentTo in interface Equivalence<Component>

Overrides:

isEquivalentTo in class Component

Parameters:

other - the component to compare to

Returns:

true if the components are of the same type and have the same props

canMeasure

protected boolean canMeasure()

Description copied from class: ComponentLifecycle

Whether this ComponentLifecycle is able to measure itself according to specific size constraints.

Overrides:

canMeasure in class ComponentLifecycle

onCreateLayoutWithSizeSpec

protected Component onCreateLayoutWithSizeSpec(ComponentContext c,
                                               int widthSpec,
                                               int heightSpec)

Overrides:

onCreateLayoutWithSizeSpec in class ComponentLifecycle
