MultidirectionalConnectionArguments

interface MultidirectionalConnectionArguments : ForwardConnectionArguments, BackwardConnectionArguments(source)

Arguments for connections that expose all four pagination args (first, after, last, before).

Forward args take precedence over backward in toOffsetLimit; passing neither returns the first page at the default size. Forward and backward args cannot be mixed in the same request.

Java equivalent of Kotlin's viaduct.api.types.MultidirectionalConnectionArguments. The direction dispatch, math, and validation are delegated to the language-neutral shared with the Kotlin Tenant API (which validates exactly once).

Prefer ForwardConnectionArguments or BackwardConnectionArguments when only one direction is needed.

Functions

requiresTotalCountForOffsetLimit

open fun requiresTotalCountForOffsetLimit(): Boolean

Returns true if backward pagination is active (last/before) and requires total count.

toOffsetLimit

open fun toOffsetLimit(defaultPageSize: Int): OffsetLimit

Converts multidirectional pagination arguments to offset/limit.

open fun toOffsetLimit(totalCount: Int, defaultPageSize: Int): OffsetLimit

Converts multidirectional pagination arguments to offset/limit when total count is known.

validate

open fun validate()

Validates multidirectional pagination arguments.
