Examples with BoundVariables io.crate.metadata.functions.BoundVariables used on opensource projects

Example 1 with BoundVariables

use of io.crate.metadata.functions.BoundVariables in project crate by crate.

the class Functions method isMoreSpecificThan.

/**
 * One method is more specific than another if invocation handled by the first method
 * could be passed on to the other one.
 * Additionally possible variadic type signatures are taken into account,
 * an exact amount of declared type signatures is more specific than expanded variadic type signatures.
