lookupOperatorOverloads

public void lookupOperatorOverloads(SqlIdentifier opName,
 @Nullable SqlFunctionCategory category,
 SqlSyntax syntax,
 List<SqlOperator> operatorList,
 SqlNameMatcher nameMatcher)

Description copied from interface: SqlOperatorTable

Retrieves a list of operators with a given name and syntax. For example, by passing SqlSyntax.Function, the returned list is narrowed to only matching SqlFunction objects.

Specified by:

lookupOperatorOverloads in interface SqlOperatorTable

Parameters:

opName - name of operator

category - function category to look up, or null for any matching operator

syntax - syntax type of operator

operatorList - mutable list to which to append matches

nameMatcher - Name matcher

getOperatorList

public List<SqlOperator> getOperatorList()

Description copied from interface: SqlOperatorTable

Retrieves a list of all functions and operators in this table. Used for automated testing. Depending on the table type, may or may not be mutable.

Specified by:

getOperatorList in interface SqlOperatorTable

Returns:

list of SqlOperator objects
