RestEntityPropertyMap maps REST entity types to their allowed properties

Functions

This section is empty.

Types

type AndExpression 

type AndExpression struct {
	Left  *Term   `@@`
	Right []*Term `("AND" @@)*`
}

type Comparison 

type Comparison struct {
	Left     *PropertyRef `@@`
	Operator string       `@("=" | "!=" | "<>" | ">=" | "<=" | ">" | "<" | "LIKE" | "ILIKE" | "IN")`
	Right    *Value       `@@`
}

type EntityPropertyMap 

type EntityPropertyMap map[string]PropertyDefinition

EntityPropertyMap maps property names to their definitions for each entity type

type EntityType 

type EntityType string

EntityType represents the type of entity for proper query building 

const (
	EntityTypeContext   EntityType = "context"
	EntityTypeArtifact  EntityType = "artifact"
	EntityTypeExecution EntityType = "execution"
)

func GetMLMDEntityType 

func GetMLMDEntityType(restEntityType RestEntityType) EntityType

GetMLMDEntityType maps REST entity types to their underlying MLMD entity type

type Expression 

type Expression struct {
	Or *OrExpression `@@`
}

type FilterExpression 

type FilterExpression struct {
	Left     *FilterExpression
	Right    *FilterExpression
	Operator string
	Property string
	Value    interface{}
	IsLeaf   bool
}

FilterExpression represents a parsed filter expression (keeping for compatibility)

func Parse 

func Parse(input string) (*FilterExpression, error)

Parse parses a filter query string and returns the root expression This function is thread-safe and reuses a singleton parser instance

type OrExpression 

type OrExpression struct {
	Left  *AndExpression   `@@`
	Right []*AndExpression `("OR" @@)*`
}

type PropertyDefinition 

type PropertyDefinition struct {
	Location  PropertyLocation
	ValueType string // IntValueType, StringValueType, DoubleValueType, BoolValueType
	Column    string // Database column name (for entity table) or property name (for property table)
}

PropertyDefinition defines how a property should be handled

func GetPropertyDefinition 

func GetPropertyDefinition(entityType EntityType, propertyName string) PropertyDefinition

GetPropertyDefinition returns the property definition for a given entity type and property name

func GetPropertyDefinitionForRestEntity 

func GetPropertyDefinitionForRestEntity(restEntityType RestEntityType, propertyName string) PropertyDefinition

GetPropertyDefinitionForRestEntity returns property definition for a REST entity type This function determines the correct data type and storage location for properties

type PropertyLocation 

type PropertyLocation int

PropertyLocation indicates where a property is stored 

const (
	EntityTable   PropertyLocation = iota // Property is a column in the main entity table
	PropertyTable                         // Property is stored in the entity's property table
	Custom                                // Property is a custom property in the property table
)

type PropertyRef 

type PropertyRef struct {
	EscapedName string `@EscapedIdent`
	Name        string `| @Ident`
	Type        string `("." @("string_value" | "double_value" | "int_value" | "bool_value"))?`
}

type PropertyReference 

type PropertyReference struct {
	Name      string
	IsCustom  bool
	ValueType string // StringValueType, DoubleValueType, IntValueType, BoolValueType
	IsEscaped bool   // whether the property name was escaped with backticks
}

PropertyReference represents a property reference with type information

type QueryBuilder 

type QueryBuilder struct {
	// contains filtered or unexported fields
}

QueryBuilder builds GORM queries from filter expressions It handles special cases like prefixed names for child entities (e.g., ModelVersion, ExperimentRun) where names are stored as "parentId:actualName" in the database

func NewQueryBuilderForRestEntity 

func NewQueryBuilderForRestEntity(restEntityType RestEntityType) *QueryBuilder

NewQueryBuilderForRestEntity creates a new query builder for the specified REST entity type

func (*QueryBuilder) BuildQuery 

func (qb *QueryBuilder) BuildQuery(db *gorm.DB, expr *FilterExpression) *gorm.DB

BuildQuery builds a GORM query from a filter expression

type RestEntityType 

type RestEntityType string

RestEntityType represents the specific REST API entity type 

const (
	// Context-based REST entities
	RestEntityRegisteredModel    RestEntityType = "RegisteredModel"
	RestEntityModelVersion       RestEntityType = "ModelVersion"
	RestEntityInferenceService   RestEntityType = "InferenceService"
	RestEntityServingEnvironment RestEntityType = "ServingEnvironment"
	RestEntityExperiment         RestEntityType = "Experiment"
	RestEntityExperimentRun      RestEntityType = "ExperimentRun"

	// Artifact-based REST entities
	RestEntityModelArtifact RestEntityType = "ModelArtifact"
	RestEntityDocArtifact   RestEntityType = "DocArtifact"
	RestEntityDataSet       RestEntityType = "DataSet"
	RestEntityMetric        RestEntityType = "Metric"
	RestEntityParameter     RestEntityType = "Parameter"

	// Execution-based REST entities
	RestEntityServeModel RestEntityType = "ServeModel"
)

type SingleValue 

type SingleValue struct {
	String  *string  `@String`
	Integer *int64   `| @Int`
	Float   *float64 `| @Float`
	Boolean *string  `| @("true" | "false" | "TRUE" | "FALSE")`
}

type Term 

type Term struct {
	Group      *Expression `"(" @@ ")"`
	Comparison *Comparison `| @@`
}

type Value 

type Value struct {
	String    *string    `@String`
