public final class SingleComponentSection
extends Section

This is the simplest Section within a Sections hierarchy and it can be used to represent one row in a complex list.

 final Section loadingSection = SingleComponentSection.create(c)
      .component(MyComponent.create(c).build())
      .isFullSpan(true)
      .build();

Method Detail

isEquivalentProps

public boolean isEquivalentProps(Section other,
                                 boolean shouldCompareCommonProps)

Overrides:

isEquivalentProps in class Section

makeShallowCopy

public SingleComponentSection makeShallowCopy(boolean deepCopy)

Overrides:

makeShallowCopy in class Section

Returns:

a clone of this Section. if deepCopy is false the clone won't contain any children or count as it will be returned in a pre - ChangeSet generation state.

create

public static SingleComponentSection.Builder create(SectionContext context)

generateChangeSet

protected void generateChangeSet(SectionContext context,
                                 ChangeSet changeSet,
                                 SectionContext _prevScopedContext,
                                 Section _prevAbstractImpl,
                                 SectionContext _nextScopedContext,
                                 Section _nextAbstractImpl)

Description copied from class: SectionLifecycle

This method will delegate to the DiffSectionSpec method annotated with OnDiff

Overrides:

generateChangeSet in class SectionLifecycle

isDiffSectionSpec

public boolean isDiffSectionSpec()

Overrides:

isDiffSectionSpec in class SectionLifecycle

Returns:

true if this lifecycle will generate a changeSet. If false this lifecycle will instead implement createChildren.
