Methods

Leaf(SqlNodeBase)

Creates a new SqlNodeMutatorContext.MutationResult instance with IsNode equal to false.

[Pure]
protected static SqlNodeMutatorContext.MutationResult Leaf(SqlNodeBase value)

Parameters

value SqlNodeBase: SQL node that is the result of a mutation.

Returns

SqlNodeMutatorContext.MutationResult: New SqlNodeMutatorContext.MutationResult instance.

Mutate(SqlNodeBase, SqlNodeAncestors)

Mutates the provided node.

[Pure]
protected virtual SqlNodeMutatorContext.MutationResult Mutate(SqlNodeBase node, SqlNodeAncestors ancestors)

Parameters

node SqlNodeBase: Node to mutate.
ancestors SqlNodeAncestors: SqlNodeAncestors associated with the node to mutate.

Returns

SqlNodeMutatorContext.MutationResult: Mutation result.

Remarks

See Node(SqlNodeBase) and Leaf(SqlNodeBase) for more information on how the result affects an SQL syntax tree traversal.

Node(SqlNodeBase)
