Method Detail

allowConstantFolding

public boolean allowConstantFolding()

Description copied from interface: Function

Returns true if the function always returns the same value for the same parameters. If so, it is possible to optimize the generated code through the process of "constant folding". https://en.wikipedia.org/wiki/Constant_folding

Specified by:

allowConstantFolding in interface Function

Overrides:

allowConstantFolding in class AbstractFunction

Returns:

true if this function allow constant folding optimization.
