Interface CelFunctionBinding

All Known Subinterfaces:

InternalCelFunctionBinding

@Immutable
public interface CelFunctionBinding

Binding consisting of an overload id, a Java-native argument signature, and an overload definition.

While the CEL function has a human-readable camelCase name, overload ids should use the following convention where all <type> names should be ASCII lower-cased. For types prefer the unparameterized simple name of time, or unqualified name of any proto-based type:

• unary member function: _
• binary member function: __
• unary global function: _
• binary global function: __
• global function: ___

Examples: string_startsWith_string, mathMax_list, lessThan_money_money

Method Summary

Modifier and Type	Method	Description
static <T> CelFunctionBinding	from(java.lang.String overloadId, java.lang.Class<T> arg, CelFunctionOverload.Unary<T> impl)	Create a unary function binding from the overloadId, arg, and impl.
static <T1,T2> CelFunctionBinding	from(java.lang.String overloadId, java.lang.Class<T1> arg1, java.lang.Class<T2> arg2, CelFunctionOverload.Binary<T1,T2> impl)	Create a binary function binding from the overloadId, arg1, arg2, and impl.
static CelFunctionBinding	from(java.lang.String overloadId, java.lang.Iterable<java.lang.Class<?>> argTypes, CelFunctionOverload impl)	Create a function binding from the overloadId, argTypes, and impl.
static com.google.common.collect.ImmutableSet<CelFunctionBinding>	fromOverloads(java.lang.String functionName, CelFunctionBinding... overloadBindings)	See fromOverloads(String, Collection).
static com.google.common.collect.ImmutableSet<CelFunctionBinding>	fromOverloads(java.lang.String functionName, java.util.Collection<CelFunctionBinding> overloadBindings)	Creates a set of bindings for a function, enabling dynamic dispatch logic to select the correct overload at runtime based on argument types.
