Method Details

getMonotonicity

public SqlMonotonicity getMonotonicity(SqlOperatorBinding call)

Description copied from class: SqlOperator

Returns whether a call to this operator is monotonic.

Default implementation returns SqlMonotonicity.NOT_MONOTONIC.

Overrides:

getMonotonicity in class SqlOperator

Parameters:

call - Call to this operator with particular arguments and information about the monotonicity of the arguments
