getPointer

public Pointer getPointer(long offset)

从类复制的说明: Pointer

Reads an Pointer value at the given offset.

指定者:

getPointer 在类中 Pointer

参数:

offset - the offset from the start of the memory this Pointer represents at which the value will be read.

返回:

the Pointer value read from memory.

getPointer

public Pointer getPointer(long offset,
                          long size)

从类复制的说明: Pointer

Reads an Pointer value at the given offset.

指定者:

getPointer 在类中 Pointer

参数:

offset - the offset from the start of the memory this Pointer represents at which the value will be read.

size - the maximum size of the memory location the returned Pointer represents.

返回:

the Pointer value read from memory.

putPointer

public void putPointer(long offset,
                       Pointer value)

从类复制的说明: Pointer

Writes a Pointer value at the given offset.

指定者:

putPointer 在类中 Pointer

参数:

offset - The offset from the start of the memory this Pointer represents at which the value will be written.

value - the Pointer value to be written to memory.
