public Type findType(NativeType type)

Implements abstract jnr.ffi.Runtime.findType.

Doc from jnr.ffi.Runtime.findType.

Looks up the runtime-specific type that corresponds to the pseudo-type

Parameters
type:NativeType

The native pseudo-type.

Returns:Type

A Type instance.

public Type findType(TypeAlias type)

Implements abstract jnr.ffi.Runtime.findType.

Doc from jnr.ffi.Runtime.findType.

Looks up the runtime-specific type that corresponds to the type alias

Parameters
type:TypeAlias

the type alias.

Returns:Type

A Type instance

Annotations

public ClosureManager getClosureManager()

Implements abstract jnr.ffi.Runtime.getClosureManager.

Doc from jnr.ffi.Runtime.getClosureManager.

Gets the native closure manager for this runtime

Returns:ClosureManager

Annotations
@Override
getLastErrorback to summary
public int getLastError()

Implements abstract jnr.ffi.Runtime.getLastError.

Doc from jnr.ffi.Runtime.getLastError.

Gets the last native error code.

This returns the errno value that was set at the time of the last native function call.

Returns:int

The errno value.

Annotations

@Override
isCompatibleback to summary
public boolean isCompatible(Runtime other)

Implements abstract jnr.ffi.Runtime.isCompatible.

Doc from jnr.ffi.Runtime.isCompatible.

Indicates whether this Runtime instance is compatible with another Runtime instance.

This is not the same as calling equals - this method only indicates whether or not artifacts from the runtime (e.g. memory addresses) are compatible with artifacts from this one.

This is mostly for internal use.

Parameters
other:Runtime

the other runtime to test for compatibility

Returns:boolean

true if the other runtime is compatible with this one
