ReadChar() 

public char ReadChar()

Returns

ReadCharLe()

Reads a Unicode character from this stream in little-endian order. This method reads two bytes from the stream, starting at the current stream pointer. This method blocks until the two bytes are read, the end of the stream is detected, or an exception is thrown. @exception EOFException if this stream reaches the end before reading two bytes. @exception IOException if an I/O error occurs.

public char ReadCharLe()

Returns

char

the next two bytes of this stream as a Unicode character.

ReadDouble() 

public double ReadDouble()

Returns

double

ReadDoubleLe() 

public double ReadDoubleLe()

Returns

double

ReadFloat() 

public float ReadFloat()

Returns

float

ReadFloatLe() 

public float ReadFloatLe()

Returns

float

ReadFully(byte[]) 

public void ReadFully(byte[] b)

Parameters

b byte[]

ReadFully(byte[], int, int) 

public void ReadFully(byte[] b, int off, int len)

Parameters

b byte[]
off int
len int

ReadInt() 

public int ReadInt()

Returns

int

ReadIntLe()

Reads a signed 32-bit integer from this stream in little-endian order. This method reads 4 bytes from the stream, starting at the current stream pointer. This method blocks until the four bytes are read, the end of the stream is detected, or an exception is thrown. int . @exception EOFException if this stream reaches the end before reading four bytes. @exception IOException if an I/O error occurs.

public int ReadIntLe()

Returns

int

the next four bytes of this stream, interpreted as an

ReadLine() 

public string ReadLine()

Returns

string

ReadLong() 

public long ReadLong()

Returns

long

ReadLongLe() 

public long ReadLongLe()

Returns

long

ReadShort() 

public short ReadShort()

Returns

short

ReadShortLe()

Reads a signed 16-bit number from this stream in little-endian order. The method reads two bytes from this stream, starting at the current stream pointer. If the two bytes read, in order, are b1 and b2 , where each of the two values is between 0 and 255 , inclusive, then the result is equal to: (short)((b2 << 8) | b1) This method blocks until the two bytes are read, the end of the stream is detected, or an exception is thrown. 16-bit number. @exception EOFException if this stream reaches the end before reading two bytes. @exception IOException if an I/O error occurs.

public short ReadShortLe()

Returns

short

the next two bytes of this stream, interpreted as a signed

ReadUnsignedByte() 

public int ReadUnsignedByte()

Returns

int

ReadUnsignedInt()

Reads an unsigned 32-bit integer from this stream. This method reads 4 bytes from the stream, starting at the current stream pointer. This method blocks until the four bytes are read, the end of the stream is detected, or an exception is thrown. long . @exception EOFException if this stream reaches the end before reading four bytes. @exception IOException if an I/O error occurs.

public long ReadUnsignedInt()

Returns

long

the next four bytes of this stream, interpreted as a

ReadUnsignedIntLe() 

public long ReadUnsignedIntLe()

Returns

long

ReadUnsignedShort() 

public int ReadUnsignedShort()

Returns

int

ReadUnsignedShortLe()

Reads an unsigned 16-bit number from this stream in little-endian order. This method reads two bytes from the stream, starting at the current stream pointer. This method blocks until the two bytes are read, the end of the stream is detected, or an exception is thrown. unsigned 16-bit integer. @exception EOFException if this stream reaches the end before reading two bytes. @exception IOException if an I/O error occurs.
