Types ¶
type Constraint ¶
type Constraint struct{}
Constraint is a clause generating a Constraint statement, ensuring uniqueness among properties for given relationship types or node labels.
func (*Constraint) Generate ¶
func (c *Constraint) Generate(seed *seed.Seed, s *schema.Schema) []translator.Clause
Generate subclauses for Constraint
type ConstraintProperty ¶
type ConstraintProperty struct {
VarName string
}
A ConstraintProperty is a single property over which the constraint is set.
func (*ConstraintProperty) Generate ¶
func (c *ConstraintProperty) Generate(seed *seed.Seed, s *schema.Schema) []translator.Clause
Generate subclauses for ConstraintProperty
func (ConstraintProperty) TemplateString ¶
func (c ConstraintProperty) TemplateString() string
TemplateString for ConstraintProperty
type ConstraintPropertyChain ¶
type ConstraintPropertyChain struct {
VarName string
// contains filtered or unexported fields
}
ConstraintPropertyChain represents a chain of properties over which the constraints are set.
func (*ConstraintPropertyChain) Generate ¶
func (c *ConstraintPropertyChain) Generate(seed *seed.Seed, s *schema.Schema) []translator.Clause
Generate subclauses for ConstraintPropertyChain
func (ConstraintPropertyChain) TemplateString ¶
func (c ConstraintPropertyChain) TemplateString() string
TemplateString for ConstraintPropertyChain
type DropIndex ¶
type DropIndex struct {
// contains filtered or unexported fields
}
DropIndex represents the statement dropping an existing index.
func (DropIndex) TemplateString ¶
TemplateString for DropIndex
type Index ¶
type Index struct {
// contains filtered or unexported fields
}
Index is the Neo4j implementation for creating or dropping a database index as well as for creating constraints on properties.
func (*Index) Transform ¶
func (c *Index) Transform(seed *seed.Seed, s *schema.Schema, subclauses []translator.Clause) translator.Clause
Transform an Index to an equivalent by having it evaluate in a (semantically) empty query. Creating an index only has an impact on query performance, not its result. Thus, omitting the index creation should have no effect on the query's outcome.
type IndexOnLabels ¶
type IndexOnLabels struct {
// contains filtered or unexported fields
}
IndexOnLabels generates an index that indexes on labels. Applicable for index types: lookup
func (*IndexOnLabels) Generate ¶
func (c *IndexOnLabels) Generate(seed *seed.Seed, s *schema.Schema) []translator.Clause
Generate subclauses for IndexOnLabels
func (IndexOnLabels) TemplateString ¶
func (c IndexOnLabels) TemplateString() string
TemplateString for IndexOnLabels
type IndexOnProperties ¶
type IndexOnProperties struct {
// contains filtered or unexported fields
}
IndexOnProperties generates an index that indexes multiple properties. Applicable for index types: range
func (*IndexOnProperties) Generate ¶
func (c *IndexOnProperties) Generate(seed *seed.Seed, s *schema.Schema) []translator.Clause
Generate subclauses for IndexOnProperties
func (IndexOnProperties) TemplateString ¶
func (c IndexOnProperties) TemplateString() string
TemplateString for IndexOnProperties
type IndexOnPropertiesProperties ¶
type IndexOnPropertiesProperties struct {
// contains filtered or unexported fields
}
IndexOnPropertiesProperties represents the properties on which the IndexOnProperties generates the index
func (*IndexOnPropertiesProperties) Generate ¶
func (c *IndexOnPropertiesProperties) Generate(seed *seed.Seed, s *schema.Schema) []translator.Clause
Generate subclauses for IndexOnPropertiesProperties
func (IndexOnPropertiesProperties) TemplateString ¶
func (c IndexOnPropertiesProperties) TemplateString() string
TemplateString for IndexOnPropertiesProperties
type IndexOnProperty ¶
type IndexOnProperty struct {
// contains filtered or unexported fields
}
IndexOnProperty generates an index that only indexes on a single property. Applicable for index types: text, point
func (*IndexOnProperty) Generate ¶
func (c *IndexOnProperty) Generate(seed *seed.Seed, s *schema.Schema) []translator.Clause
Generate subclauses for IndexOnProperty
func (IndexOnProperty) TemplateString ¶
func (c IndexOnProperty) TemplateString() string
TemplateString for IndexOnProperty
type NodeConstraint ¶
type NodeConstraint struct{}
NodeConstraint creates a UNIQUE constraint on nodes.
func (*NodeConstraint) Generate ¶
func (c *NodeConstraint) Generate(seed *seed.Seed, s *schema.Schema) []translator.Clause
Generate subclauses for NodeConstraint
func (*NodeConstraint) TemplateString ¶
func (c *NodeConstraint) TemplateString() string
TemplateString for NodeConstraint
type RelationshipConstraint ¶
type RelationshipConstraint struct{}
RelationshipConstraint creates a UNIQUE constraint on relationships.
func (*RelationshipConstraint) Generate ¶
func (c *RelationshipConstraint) Generate(seed *seed.Seed, s *schema.Schema) []translator.Clause
Generate subclauses for RelationshipConstraint
func (*RelationshipConstraint) TemplateString ¶
func (c *RelationshipConstraint) TemplateString() string
TemplateString for RelationshipConstraint
