getMappingsList

List<GraphAlgebra.Project.ExprAlias> getMappingsList()

 A list of [expression -> alias] to be projected from the graph relation.
 e.g., project_{a.birthday / 100 % 100 as birth_month }
 

repeated .algebra.Project.ExprAlias mappings = 1;

getMappings

GraphAlgebra.Project.ExprAlias getMappings(int index)

 A list of [expression -> alias] to be projected from the graph relation.
 e.g., project_{a.birthday / 100 % 100 as birth_month }
 

repeated .algebra.Project.ExprAlias mappings = 1;

getMappingsCount

int getMappingsCount()

 A list of [expression -> alias] to be projected from the graph relation.
 e.g., project_{a.birthday / 100 % 100 as birth_month }
 

repeated .algebra.Project.ExprAlias mappings = 1;

getMappingsOrBuilderList

List<? extends GraphAlgebra.Project.ExprAliasOrBuilder> getMappingsOrBuilderList()

 A list of [expression -> alias] to be projected from the graph relation.
 e.g., project_{a.birthday / 100 % 100 as birth_month }
 

repeated .algebra.Project.ExprAlias mappings = 1;

getMappingsOrBuilder

GraphAlgebra.Project.ExprAliasOrBuilder getMappingsOrBuilder(int index)
