Constructor Details

PanamaFunction

public PanamaFunction(PanamaInstance instance,
 String name,
 ai.tegmentum.wasmtime4j.type.FunctionType functionType)

Creates a new Panama function that delegates to an instance.

Parameters:

instance - the instance containing this function

name - the function name

functionType - the function type signature

Method Details

call

public ai.tegmentum.wasmtime4j.WasmValue[] call(ai.tegmentum.wasmtime4j.WasmValue... params)
                                         throws ai.tegmentum.wasmtime4j.exception.WasmException

Specified by:

call in interface ai.tegmentum.wasmtime4j.WasmFunction

Throws:

ai.tegmentum.wasmtime4j.exception.WasmException

getFunctionType

public ai.tegmentum.wasmtime4j.type.FunctionType getFunctionType()

Specified by:

getFunctionType in interface ai.tegmentum.wasmtime4j.WasmFunction

getName

public String getName()

Specified by:

getName in interface ai.tegmentum.wasmtime4j.WasmFunction

asTyped

public ai.tegmentum.wasmtime4j.func.TypedFunc asTyped(String signature)

Creates a typed function wrapper with the specified signature.

This method provides zero-cost typed function calls by eliminating runtime type checking overhead. The signature string encodes parameter and return types in a compact format.

Specified by:

asTyped in interface ai.tegmentum.wasmtime4j.func.TypedFunc.TypedFunctionSupport

Parameters:

signature - the signature string (e.g., "ii->i" for (i32, i32) -> i32)

Returns:

a new TypedFunc instance wrapping this function

Throws:

IllegalArgumentException - if signature is invalid

callAsync

public CompletableFuture<ai.tegmentum.wasmtime4j.WasmValue[]> callAsync(ai.tegmentum.wasmtime4j.WasmValue... params)

Specified by:

callVoid

public void callVoid()
              throws ai.tegmentum.wasmtime4j.exception.WasmException

Specified by:
