static fun copy(input: java.io.InputStream, output: java.io.OutputStream): int
Copy bytes from an InputStream to an OutputStream.
This method buffers the input internally, so there is no need to use a BufferedInputStream.
Large streams (over 2GB) will return a bytes copied value of -1 after the copy has completed since the correct number of bytes cannot be returned as an int. For large streams use the copyLarge(InputStream, OutputStream) method.
input - java.io.InputStream: the InputStream to read from
output - java.io.OutputStream: the OutputStream to write to
NullPointerException - if the input or output is null
IOException - if an I/O error occurs
ArithmeticException - if the byte count is too large
Return
int: the number of bytes copied

static fun copy(input: java.io.InputStream, output: java.io.Writer): void
Copy bytes from an InputStream to chars on a Writer using the default character encoding of the platform.
This method buffers the input internally, so there is no need to use a BufferedInputStream.
This method uses InputStreamReader.

static fun copy(input: java.io.InputStream, output: java.io.Writer, encoding: java.lang.String): void
Copy bytes from an InputStream to chars on a Writer using the specified character encoding.
This method buffers the input internally, so there is no need to use a BufferedInputStream.
Character encoding names can be found at IANA.
This method uses InputStreamReader.
input - java.io.InputStream: the InputStream to read from
output - java.io.Writer: the Writer to write to
encoding - java.lang.String: the encoding to use, null means platform default

static fun copy(input: java.io.Reader, output: java.io.Writer): int
Copy chars from a Reader to a Writer.
This method buffers the input internally, so there is no need to use a BufferedReader.
Large streams (over 2GB) will return a chars copied value of -1 after the copy has completed since the correct number of chars cannot be returned as an int. For large streams use the copyLarge(Reader, Writer) method.

output - java.io.Writer: the Writer to write to

ArithmeticException - if the character count is too large
Return
int: the number of characters copied

static fun copy(input: java.io.Reader, output: java.io.OutputStream): void
Copy chars from a Reader to bytes on an OutputStream using the default character encoding of the platform, and calling flush.
This method buffers the input internally, so there is no need to use a BufferedReader.
Due to the implementation of OutputStreamWriter, this method performs a flush.
This method uses OutputStreamWriter.
