Method Detail

getInstance

public static NativeRuntime getInstance()

findType

public Type findType(TypeAlias type)

Description copied from class: Runtime

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

Specified by:

findType in class Runtime

Returns:

A Type instance

getMemoryManager

public final NativeMemoryManager getMemoryManager()

Description copied from class: AbstractRuntime

Gets the native memory manager instance for this runtime

Specified by:

getMemoryManager in class AbstractRuntime

Returns:

a MemoryManager

getClosureManager

public jnr.ffi.provider.jffi.NativeClosureManager getClosureManager()

Description copied from class: Runtime

Gets the native closure manager for this runtime

Specified by:

getClosureManager in class Runtime

Returns:

The ClosureManager of the runtime

newObjectReferenceManager

public ObjectReferenceManager newObjectReferenceManager()

Description copied from class: Runtime

Creates a new ObjectReferenceManager

Specified by:

newObjectReferenceManager in class Runtime

Returns:

A new ObjectReferenceManager

getLastError

public int getLastError()

Description copied from class: AbstractRuntime

Gets the last native error code.

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

Specified by:

getLastError in class AbstractRuntime

Returns:

The errno value.

setLastError

public void setLastError(int error)

Description copied from class: AbstractRuntime

Sets the native error code.

Specified by:

setLastError in class AbstractRuntime

Parameters:

error - The value to set errno to.

isCompatible

public boolean isCompatible(Runtime other)

Description copied from class: Runtime

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

This is not the same as calling Object.equals(java.lang.Object) - 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.

Specified by:

isCompatible in class Runtime

Parameters:

other - the other runtime to test for compatibility

Returns:

true if the other runtime is compatible with this one

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
