Returns a buffer of method signature names that meet a number of conditional statements given as input parameters.

Arguments

1	Type	Name	Comment
2	SdaiString	typeFilter	Express-X conditional statement that will be evaluated against the method_type attribute of all the edm_method instances of the ExpressDataManager model. The method type identifier is stored as an Express enumeration data type. Hence, only conditional statements that are valid for enumerations may be used. Do not quote the method type identifier Examples: "method_type = XPX". "method_type = QEX".
3	SdaiString	nameFilter	Express-X conditional statement that will be evaluated against the name attribute of all edm_method instances of the ExpressDataManager model. Method names must be quoted and uppercase. Examples: "name LIKE 'KZ22'" "xpxLike(name, '*_OUTPUT')"
4	SdaiString	schemaFilter	Express-X conditional statement that will be evaluated against the attributes of the parent express schema of the query schema in which the query function method is defined. This filter is only applicable for query function methods. See entity definition of express_data_manager.edm_schema for list of available attributes. The conditional string must start with the attribute name. I.e no leading whitespace or parenthesis. Examples: "name = 'IFC2X2'" "original_name LIKE 'ifc2x2*'" "source_stored = TRUE"
5	SdaiString	extraSchemaFilter	Express-X conditional statement that will be evaluated against the attributes of the query schema in which the query function method is defined. This filter is only applicable for query function methods. See entity definition of express_data_manager.edm_query_schema for list of available attributes. The conditional string must start with the attribute name. I.e no leading whitespace or parenthesis. Examples: "name = 'MYQUERYFUNCS'" "original_name LIKE 'MyQuery*'" "protection ~& XPXGROUP_WRITE"
6	SdaiString	methodClassFilter	Express-X conditional statement that will be evaluated against the classification attribute of all edm_method instances of the ExpressDataManager model. Examples "classification = 'CHECK_IN'". "xpxLike(classification, 'CHECK_*')"
7	SdaiString	ownerFilter	Express-X conditional statement that will be evaluated against the attributes of the edmUser that owns the method. See entity definition of express_data_manager.edm_user for list of available attributes. The conditional string must start with the attribute name. I.e no leading whitespace or parenthesis. Examples: "name = 'JOHNNY'" "original_name LIKE 'John*'"
8	SdaiString	groupOwnerFilter	Express-X conditional statement that will be evaluated against the attributes of the edmGroup that owns the method. See entity definition of express_data_manager.edm_group for list of available attributes. The conditional string must start with the attribute name. I.e no leading whitespace or parenthesis. Examples: "name = 'SUPERVISOR'" "original_name LIKE 'Super*'"
9		options	Currently not used.
10	SdaiString	foundNames	A buffer that will receive a null terminated list of method names that meet all the given conditions.
