Method Detail

getMonotonicity

public SqlMonotonicity getMonotonicity(SqlCall call,
                              SqlValidatorScope scope)

Description copied from class: SqlOperator

Returns whether this operator is monotonic.

Default implementation returns SqlMonotonicity.NOT_MONOTONIC.

Overrides:

getMonotonicity in class SqlMonotonicUnaryFunction

Parameters:

call - Call to this operator

scope - Scope in which the call occurs

unparse

public void unparse(SqlWriter writer,
           SqlCall call,
           int leftPrec,
           int rightPrec)

Description copied from class: SqlOperator

Writes a SQL representation of a call to this operator to a writer, including parentheses if the operators on either side are of greater precedence.

The default implementation of this method delegates to SqlSyntax.unparse(org.apache.calcite.sql.SqlWriter, org.apache.calcite.sql.SqlOperator, org.apache.calcite.sql.SqlCall, int, int).

Overrides:

unparse in class SqlFunction
