Detailed Description

Base class for update requirement operations.

Represents a requirement that must be validated before applying metadata updates to a table. Each concrete subclass represents a specific type of requirement check.

Member Function Documentation

Clone()

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

pure virtual

Create a deep copy of this requirement.

Returns

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

Implemented in iceberg::table::AssertDoesNotExist, iceberg::table::AssertUUID, iceberg::table::AssertRefSnapshotID, iceberg::table::AssertLastAssignedFieldId, iceberg::table::AssertCurrentSchemaID, iceberg::table::AssertLastAssignedPartitionId, iceberg::table::AssertDefaultSpecID, and iceberg::table::AssertDefaultSortOrderID.

Equals()

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

pure virtual

Check equality with another TableRequirement.

Parameters

other

The requirement to compare with

Returns

true if the requirements are equal, false otherwise

Implemented in iceberg::table::AssertDoesNotExist, iceberg::table::AssertUUID, iceberg::table::AssertRefSnapshotID, iceberg::table::AssertLastAssignedFieldId, iceberg::table::AssertCurrentSchemaID, iceberg::table::AssertLastAssignedPartitionId, iceberg::table::AssertDefaultSpecID, and iceberg::table::AssertDefaultSortOrderID.

kind()

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

pure virtual

Return the kind of requirement.

Implemented in iceberg::table::AssertDoesNotExist, iceberg::table::AssertUUID, iceberg::table::AssertRefSnapshotID, iceberg::table::AssertLastAssignedFieldId, iceberg::table::AssertCurrentSchemaID, iceberg::table::AssertLastAssignedPartitionId, iceberg::table::AssertDefaultSpecID, and iceberg::table::AssertDefaultSortOrderID.

Validate()

virtual Status iceberg::TableRequirement::Validate ( const TableMetadata *  base ) const

pure virtual

Validate this requirement against table metadata.

Parameters

base	The base table metadata to validate against (may be nullptr)

Returns

Status indicating success or failure with error details

Implemented in iceberg::table::AssertDoesNotExist, iceberg::table::AssertUUID, iceberg::table::AssertRefSnapshotID, iceberg::table::AssertLastAssignedFieldId, iceberg::table::AssertCurrentSchemaID, iceberg::table::AssertLastAssignedPartitionId, iceberg::table::AssertDefaultSpecID, and iceberg::table::AssertDefaultSortOrderID.
