Constructor Detail

ListSqlOperatorTable

@Deprecated
public ListSqlOperatorTable()

Deprecated. Use SqlOperatorTables.of(java.lang.Iterable<? extends org.apache.calcite.sql.SqlOperator>), which creates an immutable table.

Creates an empty, mutable ListSqlOperatorTable.

ListSqlOperatorTable

@Deprecated
public ListSqlOperatorTable(List<SqlOperator> operatorList)

Deprecated. Use SqlOperatorTables.of(java.lang.Iterable<? extends org.apache.calcite.sql.SqlOperator>), which creates an immutable table.

Creates a mutable ListSqlOperatorTable backed by a given list.

Method Detail

add

@Deprecated
public void add(SqlOperator op)

Deprecated. Use SqlOperatorTables.of(java.lang.Iterable<? extends org.apache.calcite.sql.SqlOperator>), which creates an immutable table.

Adds an operator to this table.

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

category

protected static SqlFunctionCategory category(SqlOperator operator)

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
