Method Detail

copy

public static ByteString copy(ByteString source)

Copy - if the source is null, this returns null. Otherwise, the ByteString is copied.

Parameters:

source - ByteString to be copied

substring

public ByteString substring(int start,
                            int end)

Creates a ByteString substring.

Parameters:

start - the first character of the substring

end - the character after the last character of the substring

Returns:

the ByteString substring

equalsIgnoreCase

public final boolean equalsIgnoreCase(byte[] b,
                                      int pos,
                                      int len)

Check if this ByteString equals the value of the passed arguments

Parameters:

b - byte array that holds the value to check against

pos - first byte in the byte array

len - length of the value to check against

Returns:

true if this ByteString matches, false otherwise

equalsIgnoreCase

public final boolean equalsIgnoreCase(ByteString c)

Check if this ByteString is equal to the one passed in the argument.

Parameters:

c - ByteString to check against

Returns:

true if this ByteString is equal to the c ByteString, false otherwise.

equalsAtIgnoreCase

public final boolean equalsAtIgnoreCase(byte[] b,
                                        int at)

Check if this ByteString equals the byte array b, for the length of the byte array, starting at at within this ByteString.

This extends, some how, startsWidth and endsWidth, avoiding substring.

Parameters:

b - byte array that holds the value to check against

at - first byte in this ByteString

Returns:

true if this ByteString matches, false otherwise

toString

public final java.lang.String toString()

Return a String representation of this ByteString

Overrides:

toString in class java.lang.Object

Returns:

a String representation of this ByteString

indexOf

public final int indexOf(byte b,
                         int start)

Find the first byte b in this ByteString.

Parameters:

b - byte to find

start - where to start from

Returns:

the offset of the byte, if found; -1 if not found

lastIndexOf

public final int lastIndexOf(byte b)

Find the last byte b in this ByteString.

Parameters:

b - byte to find

Returns:

the offset of the byte, if found; -1 if not found

indexOf

public final int indexOf(byte[] b,
                         int start)

Find the first byte array b in this ByteString.

Parameters:

b - byte array to find

start - where to start from

Returns:

the offset of the byte array, if found; -1 if not found

convertToInt

public static int convertToInt(byte[] b,
                               int start,
                               int end)

Convert the literal representation of an int to its int value

Parameters:

b - byte array that holds the literal representation

start - where it starts in the byte array

end - where it ends

Returns:

the integer value, or -1 if wrong representation.

convertToInt

public int convertToInt(int start)

Convert the literal representation of an int to its int value

Parameters:

start - where the int represenation starts in this ByteString

Returns:

the integer value, or -1 if wrong representation.
