Class ByteSource.Util

java.lang.Object
  org.apache.shiro.util.ByteSource.Util

Enclosing interface:

ByteSource

public static final class ByteSource.Util
extends Object

Utility class that can construct ByteSource instances. This is slightly nicer than needing to know the ByteSource implementation class to use.

Since:

1.2

static ByteSource	bytes(InputStream stream) Returns a new ByteSource instance representing the specified InputStream's bytes.
static ByteSource	bytes(Object source) Returns a ByteSource instance representing the specified byte source argument.
static ByteSource	bytes(String string) Returns a new ByteSource instance representing the specified string's bytes.
static boolean	isCompatible(Object source) Returns true if the specified object can be easily represented as a ByteSource using the ByteSource.Util's default heuristics, false otherwise.

Method Detail

bytes

public static ByteSource bytes(byte[] bytes)

Returns a new ByteSource instance representing the specified byte array.

Parameters:

bytes - the bytes to represent as a ByteSource instance.

Returns:

a new ByteSource instance representing the specified byte array.

bytes

public static ByteSource bytes(char[] chars)

Returns a new ByteSource instance representing the specified character array's bytes. The byte array is obtained assuming UTF-8 encoding.

Parameters:

chars - the character array to represent as a ByteSource instance.

Returns:

a new ByteSource instance representing the specified character array's bytes.

bytes

public static ByteSource bytes(String string)

Returns a new ByteSource instance representing the specified string's bytes. The byte array is obtained assuming UTF-8 encoding.

Parameters:

string - the string to represent as a ByteSource instance.

Returns:

a new ByteSource instance representing the specified string's bytes.

bytes

public static ByteSource bytes(ByteSource source)

Returns a new ByteSource instance representing the specified ByteSource.

Parameters:

source - the ByteSource to represent as a new ByteSource instance.

Returns:

a new ByteSource instance representing the specified ByteSource.

bytes

public static ByteSource bytes(File file)

Returns a new ByteSource instance representing the specified File's bytes.

Parameters:

file - the file to represent as a ByteSource instance.

Returns:

a new ByteSource instance representing the specified File's bytes.

bytes

public static ByteSource bytes(InputStream stream)

Returns a new ByteSource instance representing the specified InputStream's bytes.

Parameters:

stream - the InputStream to represent as a ByteSource instance.

Returns:

a new ByteSource instance representing the specified InputStream's bytes.

isCompatible

public static boolean isCompatible(Object source)

Returns true if the specified object can be easily represented as a ByteSource using the ByteSource.Util's default heuristics, false otherwise.

This implementation merely returns SimpleByteSource.isCompatible(source).

Parameters:

source - the object to test to see if it can be easily converted to ByteSource instances using default heuristics.

Returns:

true if the specified object can be easily represented as a ByteSource using the ByteSource.Util's default heuristics, false otherwise.

bytes

public static ByteSource bytes(Object source)
                        throws IllegalArgumentException

Returns a ByteSource instance representing the specified byte source argument. If the argument cannot be easily converted to bytes (as is indicated by the isCompatible(Object) JavaDoc), this method will throw an IllegalArgumentException.

Parameters:

source - the byte-backed instance that should be represented as a ByteSource instance.

Returns:

a ByteSource instance representing the specified byte source argument.

Throws:

IllegalArgumentException - if the argument cannot be easily converted to bytes (as indicated by the isCompatible(Object) JavaDoc)
