Read the requested number of bytes or fail if there are not enough left.

Parameters:

input - where to read input from

buffer - destination

Throws:

java.io.IOException - if there is a problem reading the file

java.io.EOFException - if the number of bytes read was incorrect

Read the requested number of bytes or fail if there are not enough left.

Parameters:

input - where to read input from

buffer - destination

offset - initial offset into buffer

length - length to read, must be ≥ 0

Throws:

java.io.IOException - if there is a problem reading the file

java.io.EOFException - if the number of bytes read was incorrect

read

public static int read(java.io.InputStream input,

Parameters:

input - where to read input from

buffer - destination

offset - initial offset into buffer

length - length to read - ignored if non-positive

Returns:

actual length read; may be less than requested if EOF was reached

Throws:
