메소드	설명
ClrType ( TypeUsage typeUsage ) : Type	This method returns the underlying CLR type of the o-space type corresponding to the supplied typeUsage Note that for an enum type this means that the type backing the enum will be returned, not the enum type itself.
GetCorrespondingDependentProperty ( System.Data.Metadata.Edm.NavigationProperty navProperty, System.Data.Metadata.Edm.EdmProperty principalProperty ) : System.Data.Metadata.Edm.EdmProperty	Given a property on the principal end of a referential constraint, returns the corresponding property on the dependent end. Requires: The association has a referential constraint, and the specified principalProperty is one of the properties on the principal end.
GetCorrespondingPrincipalProperty ( System.Data.Metadata.Edm.NavigationProperty navProperty, System.Data.Metadata.Edm.EdmProperty dependentProperty ) : System.Data.Metadata.Edm.EdmProperty	Given a property on the dependent end of a referential constraint, returns the corresponding property on the principal end. Requires: The association has a referential constraint, and the specified dependentProperty is one of the properties on the dependent end.
GetDependentProperties ( System.Data.Metadata.Edm.NavigationProperty navProperty ) : ReadOnlyMetadataCollection	Gets the collection of properties that are on the dependent end of a referential constraint for the specified navigation property. Requires: The association has a referential constraint.
GetElementType ( TypeUsage typeUsage ) : TypeUsage	If the passed in TypeUsage represents a collection this method returns final element type of the collection, otherwise it returns the value passed in.
GetPrincipalProperties ( System.Data.Metadata.Edm.NavigationProperty navProperty ) : ReadOnlyMetadataCollection	Gets the collection of properties that are on the principal end of a referential constraint for the specified navigation property. Requires: The association has a referential constraint.

In order to be an identifying relationship, the association must have a referential constraint where all of the dependent properties are part of the dependent type's primary key.
IsSubtypeOf ( System.Data.Metadata.Edm.EdmType firstType, System.Data.Metadata.Edm.EdmType secondType ) : bool	requires: firstType is not null effects: if secondType is among the base types of the firstType, return true, otherwise returns false. when firstType is same as the secondType, return false.
MetadataTools ( object textTransformation ) : System	Initializes an MetadataTools Instance with the TextTransformation (T4 generated class) that is currently running
NeedsHandleCascadeDeleteMethod ( ItemCollection itemCollection, EntityType entity ) : bool	True if this entity type requires the HandleCascadeDelete method defined and the method has not been defined on any base type
TryGetStringMetadataPropertySetting ( System.Data.Metadata.Edm.MetadataItem item, string propertyName, string &value ) : bool
UnderlyingClrType ( System.Data.Metadata.Edm.EdmType edmType ) : Type	This method returns the underlying CLR type given the c-space type. Note that for an enum type this means that the type backing the enum will be returned, not the enum type itself.
