public abstract class SchemaDefinition

extends CEntity

It is a supertype of the class CSchema_definition contained in the jsdai.dictionary package. This class is designed primarily to hold some non-public data fields. Also, the public method getEntityDefinition defined in "ISO 10303-22: Product data representation and exchange: Standard data access interface" and additional public method getDefinedType, which is not a part of the standard, are implemented here.

Method Detail

getEntityDefinition

public jsdai.dictionary.EEntity_definition getEntityDefinition(java.lang.String entity_name)
                                                        throws SdaiException

Returns entity definition for the entity with the specified name. This method searches the set of entities that are encountered in the EXPRESS schema represented by this ESchema_definition. Method's parameter is some string giving the name of an entity. If this entity is complex, then its constituents (simple entity data types) within this string are separated by '+' character. For example, "length_unit+si_unit". Both lower case letters and upper case letters are acceptable. If this parameter does not allow to identify an entity that is known for this schema, then SdaiException ED_NDEF is thrown. Passing null value to the method's parameter results in SdaiException VA_NSET.

Parameters:

entity_name - the name of the entity whose definition is requested.

Returns:

definition of the specified entity.

Throws:

SdaiException - ED_NDEF, entity definition not defined.

SdaiException - VA_NSET, value not set.

SdaiException - SY_ERR, underlying system error.

getDefinedType

public jsdai.dictionary.EDefined_type getDefinedType(java.lang.String type_name)
                                              throws SdaiException

Returns defined type with the specified name. This method searches the set of defined types that are encountered in the EXPRESS schema represented by this ESchema_definition. Method's parameter is some string giving the name of a defined type. Both lower case letters and upper case letters are acceptable. If this parameter does not allow to identify a defined type that is known for this schema, then SdaiException VA_NVLD is thrown. Passing null value to the method's parameter results in SdaiException VA_NSET.

Parameters:

type_name - the name of the requested defined type.

Returns:

defined type.

Throws:

SdaiException - VA_NSET, value not set.

SdaiException - VA_NVLD, value invalid.

SdaiException - SY_ERR, underlying system error.
