ttyRead stream object, used to readttyread, write

There is no way to create this class separately, there are only process.stdininstances globally

1

member properties

isTTY

Boolean, always true

1
readonly Boolean TTYInputStream.isTTY;

---

isRaw

Boolean, query whether it is in raw mode, when it is true, it meansttyWhen configured to operate as raw device

1
readonly Boolean TTYInputStream.isRaw;

---

fd

Integer, queryStreamThe corresponding file descriptor value, implemented by subclasses

1
readonly Integer TTYInputStream.fd;

member function

setRawMode

set upttyWhether to work in raw mode

1
TTYInputStream TTYInputStream.setRawMode(Boolean isRawMode);

Call parameters:

• isRawMode: Boolean, if true, it means working in raw mode; otherwise, working in default mode. readStream.isRawIt will be set by this method

Return results:

• TTYInputStream, returns itself

---

read

Read data of specified size from the stream

1
Buffer TTYInputStream.read(Integer bytes = -1) async;

Call parameters:

• bytes: Integer, specifies the amount of data to be read. The default is to read data blocks of random size. The size of the data read depends on the device.

Return results:

• Buffer, returns the data read from the stream. If there is no data to read or the connection is interrupted, null is returned.

---

write

Write the given data to the stream

1
TTYInputStream.write(Buffer data) async;

Call parameters:

• data:Buffer, given the data to be written

---

flush

Write file buffer contents to physical device

1
TTYInputStream.flush() async;

---

close

Close the current stream object

1
TTYInputStream.close() async;

---

copyTo

Copy stream data to target stream

1
2
Long TTYInputStream.copyTo(Stream stm,
    Long bytes = -1) async;

Call parameters:

• stm:Stream, target stream object
• bytes: Long, number of bytes copied

Return results:

• Long, returns the number of bytes copied

---

toString

Returns the string representation of the object. Generally, "[Native Object]" is returned. The object can be re-implemented according to its own characteristics.

1
String TTYInputStream.toString();

Return results:

• String, returns the string representation of the object

---

toJSON

Returns a JSON format representation of the object, generally returning a collection of readable properties defined by the object.

1
Value TTYInputStream.toJSON(String key = "");

Call parameters:

• key: String, not used

Return results:

• Value, returns a value containing JSON serializable
