方法详细资料

findType

public final Type findType(NativeType type)

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

指定者:

findType 在类中 Runtime

参数:

type - The native pseudo-type.

返回:

A Type instance.

指定者:

addressMask 在类中 Runtime

返回:

The address mask for the runtime.

addressSize

public final int addressSize()

Gets the size of an address (e.g. a pointer) for this runtime

指定者:

addressSize 在类中 Runtime

The size of a C long integer in bytes.

byteOrder

public final ByteOrder byteOrder()

Retrieves this runtime's native byte order.

指定者:

byteOrder 在类中 Runtime

返回:

this runtime's byte order
