FileInputStream Class

Definition

Namespace:

Java.IO

Assembly:

Mono.Android.dll

A FileInputStream obtains input bytes from a file in a file system.

Remarks

A FileInputStream obtains input bytes from a file in a file system. What files are available depends on the host environment.

FileInputStream is meant for reading streams of raw bytes such as image data. For reading streams of characters, consider using FileReader.

Constructors

FileInputStream(File)	Creates a FileInputStream by opening a connection to an actual file, the file named by the File object file in the file system.
FileInputStream(FileDescriptor)	Creates a FileInputStream by using the file descriptor fdObj, which represents an existing connection to an actual file in the file system.
FileInputStream(IntPtr, JniHandleOwnership)	A constructor used when creating managed representations of JNI objects; called by the runtime.
FileInputStream(String)	Creates a FileInputStream by opening a connection to an actual file, the file named by the path name name in the file system.

Properties

Channel	Returns the unique java.nio.channels.FileChannel FileChannel object associated with this file input stream.
Class	Returns the runtime class of this Object. (Inherited from Object)
FD	Returns the FileDescriptor object that represents the connection to the actual file in the file system being used by this FileInputStream.
Handle	The handle to the underlying Android instance. (Inherited from Object)
JniIdentityHashCode	(Inherited from Object)
JniPeerMembers
PeerReference	(Inherited from Object)
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 a byte of data from this input stream.
Read(Byte[], Int32, Int32)	Reads up to len bytes of data from the input stream into an array of bytes. (Inherited from InputStream)
Read(Byte[])	Reads some number of bytes from the input stream and stores them into the buffer array b. (Inherited from InputStream)
ReadAllBytes()	Reads all remaining bytes from the input stream. (Inherited from InputStream)
ReadAsync()	(Inherited from InputStream)
ReadAsync(Byte[], Int32, Int32)	(Inherited from InputStream)
ReadAsync(Byte[])	(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)
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, 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)
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)
