Detailed Description

Base class for metadata update operations.

Represents a change to table metadata. Each concrete subclass represents a specific type of update operation.

Member Function Documentation

ApplyTo()

virtual void iceberg::TableUpdate::ApplyTo ( TableMetadataBuilder &  builder ) const

pure virtual

Apply this update to a TableMetadataBuilder.

This method modifies the builder by applying the update operation it represents. Each subclass implements this to apply its specific type of update.

Parameters

builder

The builder to apply this update to

Clone()

virtual std::unique_ptr< TableUpdate > iceberg::TableUpdate::Clone ( ) const

pure virtual

Create a deep copy of this update.

Returns

A unique_ptr to a new TableUpdate that is a copy of this one

Equals()

virtual bool iceberg::TableUpdate::Equals ( const TableUpdate &  other ) const

pure virtual

Check equality with another TableUpdate.

Parameters

other

The update to compare with

Returns

true if the updates are equal, false otherwise

Implemented in iceberg::table::AssignUUID, iceberg::table::UpgradeFormatVersion, iceberg::table::AddSchema, iceberg::table::SetCurrentSchema, iceberg::table::AddPartitionSpec, iceberg::table::SetDefaultPartitionSpec, iceberg::table::RemovePartitionSpecs, iceberg::table::RemoveSchemas, iceberg::table::AddSortOrder, iceberg::table::SetDefaultSortOrder, iceberg::table::AddSnapshot, iceberg::table::RemoveSnapshots, iceberg::table::RemoveSnapshotRef, iceberg::table::SetSnapshotRef, iceberg::table::SetProperties, iceberg::table::RemoveProperties, iceberg::table::SetLocation, iceberg::table::SetStatistics, iceberg::table::RemoveStatistics, iceberg::table::SetPartitionStatistics, and iceberg::table::RemovePartitionStatistics.

GenerateRequirements()

virtual void iceberg::TableUpdate::GenerateRequirements ( TableUpdateContext &  context ) const

pure virtual

Generate update requirements for this metadata update.

This method generates the appropriate UpdateRequirement instances that must be validated before this update can be applied. The context provides information about the base metadata and operation mode.

Parameters

context

The context containing base metadata and operation state

kind()

virtual Kind iceberg::TableUpdate::kind ( ) const

pure virtual

Return the kind of this update.

Implemented in iceberg::table::AssignUUID, iceberg::table::UpgradeFormatVersion, iceberg::table::AddSchema, iceberg::table::SetCurrentSchema, iceberg::table::AddPartitionSpec, iceberg::table::SetDefaultPartitionSpec, iceberg::table::RemovePartitionSpecs, iceberg::table::RemoveSchemas, iceberg::table::AddSortOrder, iceberg::table::SetDefaultSortOrder, iceberg::table::AddSnapshot, iceberg::table::RemoveSnapshots, iceberg::table::RemoveSnapshotRef, iceberg::table::SetSnapshotRef, iceberg::table::SetProperties, iceberg::table::RemoveProperties, iceberg::table::SetLocation, iceberg::table::SetStatistics, iceberg::table::RemoveStatistics, iceberg::table::SetPartitionStatistics, and iceberg::table::RemovePartitionStatistics.
