Method Detail

getRef

public TypeRef<? extends Type> getRef()

Description copied from interface: Type

Gets a proxy (or reference to this type).

Specified by:

getRef in interface Type

Returns:

a reference to the type

getHelper

public TypeHelper getHelper()

Description copied from interface: Type

Get the type helper. Must never return null

The type helper is used to handle operations on value of that type.

Specified by:

getHelper in interface Type

Returns:

the type helper

getSuperType

public Type getSuperType()

Description copied from interface: Type

Gets the super type.

Specified by:

getSuperType in interface Type

Returns:

the super type or null if this is a primitive type

getName

public String getName()

Description copied from interface: Type

Gets the name of this type.

Specified by:

getName in interface Type

Returns:

the type name

getSchemaName

public String getSchemaName()

Description copied from interface: Type

Gets the local name of this type.

Specified by:

getSchemaName in interface Type

Returns:

the local name

getSchema

public Schema getSchema()

Description copied from interface: Type

Gets the schema defining this type.

getSchema in interface Type

Returns:

isSuperTypeOf

public boolean isSuperTypeOf(Type type)

Description copied from interface: Type

Tests whether the given type is derived from this type.

Specified by:

isSuperTypeOf in interface Type

Parameters:

type - the type to test

Returns:

true if the given type is derived from this type, false otherwise

isAny

public boolean isAny()

getTypeHierarchy

public Type[] getTypeHierarchy()

Description copied from interface: Type

Gets the entire hierarchy of super-types.

The array is ordered as follows:

• the direct super type is the first element,
• the super super type is the second element,
• and so on.

The returned array is never null. An empty array is returned in the case of ANY type.

Specified by:

getTypeHierarchy in interface Type

Returns:

an array containing the supertypes of this type

Specified by:

isSimpleType in interface Type

Returns:

true if this type is a simple type, false otherwise

isComplexType

public boolean isComplexType()

Description copied from interface: Type

Tests whether this type is a complex type.

Specified by:

isComplexType in interface Type

Returns:

true if this type is a complex type, false otherwise

isListType

public boolean isListType()

Description copied from interface: Type

Tests whether this type is a list type.

Specified by:

isListType in interface Type

Returns:

true if is a list type, false otherwise

isAnyType

public boolean isAnyType()

Description copied from interface: Type

Tests whether this type is the ANY type.

Specified by:

isAnyType in interface Type

Returns:

true if it is the ANY type, false otherwise

isCompositeType

public boolean isCompositeType()

Description copied from interface: Type

Tests whether this is a composite type.

Specified by:

isCompositeType in interface Type

true if this is a composite type, false otherwise

isNotNull

public boolean isNotNull()

Description copied from interface: Type

Tests whether this type supports null values.

Specified by:

isNotNull in interface Type

Returns:

false if an object of this type can be null, true otherwise

isReadOnly

public boolean isReadOnly()

Description copied from interface: Type

Tests whether this type is read-only.

Specified by:

isReadOnly in interface Type

                 throws TypeException

Description copied from interface: Type

Tests whether the given object is of this type.

Specified by:

validate in interface Type

Parameters:
