A PushbackInputStream adds functionality to another input stream, namely the ability to "push back" or "unread" bytes, by storing pushed-back bytes in an internal buffer.

Remarks

A PushbackInputStream adds functionality to another input stream, namely the ability to "push back" or "unread" bytes, by storing pushed-back bytes in an internal buffer. This is useful in situations where it is convenient for a fragment of code to read an indefinite number of data bytes that are delimited by a particular byte value; after reading the terminating byte, the code fragment can "unread" it, so that the next read operation on the input stream will reread the byte that was pushed back. For example, bytes representing the characters constituting an identifier might be terminated by a byte representing an operator character; a method whose job is to read just an identifier can read until it sees the operator and then push the operator back to be re-read.

Constructors

PushbackInputStream(IntPtr, JniHandleOwnership)	A constructor used when creating managed representations of JNI objects; called by the runtime.
PushbackInputStream(Stream)	Creates a `PushbackInputStream` with a 1-byte pushback buffer, and saves its argument, the input stream `in`, for later use.
PushbackInputStream(Stream, Int32)	Creates a `PushbackInputStream` with a pushback buffer of the specified `size`, and saves its argument, the input stream `in`, for later use.

Properties

Buf	The pushback buffer.
Class	Returns the runtime class of this `Object`. (Inherited from Object)
Handle	The handle to the underlying Android instance. (Inherited from Object)
In	The input stream to be filtered. (Inherited from FilterInputStream)
JniIdentityHashCode	(Inherited from Object)
JniPeerMembers
PeerReference	(Inherited from Object)
Pos	The position within the pushback buffer from which the next byte will be read.
ThresholdClass	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.
ThresholdType	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.

Methods

Available()	Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking, which may be 0, or 0 when end of stream is detected. (Inherited from InputStream)
Clone()	Creates and returns a copy of this object. (Inherited from Object)
Close()	Closes this input stream and releases any system resources associated with the stream. (Inherited from InputStream)
Dispose()	(Inherited from Object)
Dispose(Boolean)	(Inherited from Object)
Equals(Object)	Indicates whether some other object is "equal to" this one. (Inherited from Object)
GetHashCode()	Returns a hash code value for the object. (Inherited from Object)
JavaFinalize()	Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object)
Mark(Int32)	Marks the current position in this input stream. (Inherited from InputStream)
MarkSupported()	Tests if this input stream supports the `mark` and `reset` methods. (Inherited from InputStream)
Notify()	Wakes up a single thread that is waiting on this object's monitor. (Inherited from Object)
NotifyAll()	Wakes up all threads that are waiting on this object's monitor. (Inherited from Object)
Read()	Reads the next byte of data from this input stream. (Inherited from FilterInputStream)
Read(Byte[])	Reads some number of bytes from the input stream and stores them into the buffer array `b`. (Inherited from InputStream)
Read(Byte[], Int32, Int32)	Reads up to `len` bytes of data from the input stream into an array of bytes. (Inherited from InputStream)
ReadAllBytes()	Reads all remaining bytes from the input stream. (Inherited from InputStream)
ReadAsync()	(Inherited from InputStream)
ReadAsync(Byte[])	(Inherited from InputStream)
ReadAsync(Byte[], Int32, Int32)	(Inherited from InputStream)
ReadNBytes(Byte[], Int32, Int32)	Reads the requested number of bytes from the input stream into the given byte array. (Inherited from InputStream)
ReadNBytes(Int32)	Reads up to a specified number of bytes from the input stream. (Inherited from InputStream)
Reset()	Repositions this stream to the position at the time the `mark` method was last called on this input stream. (Inherited from InputStream)
SetHandle(IntPtr, JniHandleOwnership)	Sets the Handle property. (Inherited from Object)
Skip(Int64)	Skips over and discards `n` bytes of data from this input stream. (Inherited from InputStream)
SkipAsync(Int64)	(Inherited from InputStream)
SkipNBytes(Int64)	Skips over and discards exactly `n` bytes of data from this input stream. (Inherited from InputStream)
ToArray<T>()	(Inherited from Object)
ToString()	Returns a string representation of the object. (Inherited from Object)
TransferTo(Stream)	Reads all bytes from this input stream and writes the bytes to the given output stream in the order that they are read. (Inherited from InputStream)
Unread(Byte[])	Pushes back an array of bytes by copying it to the front of the pushback buffer.
Unread(Byte[], Int32, Int32)	Pushes back a portion of an array of bytes by copying it to the front of the pushback buffer.
Unread(Int32)	Pushes back a byte by copying it to the front of the pushback buffer.
UnregisterFromRuntime()	(Inherited from Object)
Wait()	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>. (Inherited from Object)
Wait(Int64)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)
Wait(Int64, Int32)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)
