org.docx4j.com.google.common.collect.ImmutableSet.SetBuilderImpl<E>

org.docx4j.com.google.common.collect.ImmutableSet.RegularSetBuilderImpl<E>

Enclosing class:

ImmutableSet<E>

private static final class ImmutableSet.RegularSetBuilderImpl<E>
extends ImmutableSet.SetBuilderImpl<E>

Default implementation of the guts of ImmutableSet.Builder, creating an open-addressed hash table and deduplicating elements as they come, so it only allocates O(max(distinct, expectedCapacity)) rather than O(calls to add).

This implementation attempts to detect hash flooding, and if it's identified, falls back to JdkBackedSetBuilderImpl.

Method Details

ensureTableCapacity

void ensureTableCapacity(int minCapacity)

add

ImmutableSet.SetBuilderImpl<E> add(E e)

Description copied from class: ImmutableSet.SetBuilderImpl

Adds e to this SetBuilderImpl, returning the updated result. Only use the returned SetBuilderImpl, since we may switch implementations if e.g. hash flooding is detected.

Specified by:

add in class ImmutableSet.SetBuilderImpl<E>

copy

ImmutableSet.SetBuilderImpl<E> copy()

Description copied from class: ImmutableSet.SetBuilderImpl

Creates a new copy of this SetBuilderImpl. Modifications to that SetBuilderImpl will not affect this SetBuilderImpl or sets constructed from this SetBuilderImpl via build().

Specified by:

copy in class ImmutableSet.SetBuilderImpl<E>

review

ImmutableSet.SetBuilderImpl<E> review()

Description copied from class: ImmutableSet.SetBuilderImpl

Call this before build(). Does a final check on the internal data structures, e.g. shrinking unnecessarily large structures or detecting previously unnoticed hash flooding.

Overrides:

review in class ImmutableSet.SetBuilderImpl<E>

build

ImmutableSet<E> build()

Specified by:

build in class ImmutableSet.SetBuilderImpl<E>
