From class
java.lang.Object
|
Creates an instance of ByteArrayBuffer
with the given initial
capacity.
capacity | the capacity |
---|
Appends b
byte to this buffer. The capacity of the buffer
is increased, if necessary, to accommodate the additional byte.
b | the byte to be appended. |
---|
Appends len
chars to this buffer from the given source
array starting at index off
. The capacity of the buffer
is increased if necessary to accommodate all len
chars.
The chars are converted to bytes using simple cast.
b | the chars to be appended. |
---|---|
off | the index of the first char to append. |
len | the number of bytes to append. |
IndexOutOfBoundsException | if off if out of
range, len is negative, or
off + len is out of range.
|
---|
Appends len
bytes to this buffer from the given source
array starting at index off
. The capacity of the buffer
is increased, if necessary, to accommodate all len
bytes.
b | the bytes to be appended. |
---|---|
off | the index of the first byte to append. |
len | the number of bytes to append. |
IndexOutOfBoundsException | if off if out of
range, len is negative, or
off + len is out of range.

Appends len
chars to this buffer from the given source
char array buffer starting at index off
. The capacity
of the buffer is increased if necessary to accommodate all
len
chars.
The chars are converted to bytes using simple cast.
b | the chars to be appended. |
---|---|
off | the index of the first char to append. |
len | the number of bytes to append. |
IndexOutOfBoundsException | if off if out of
range, len is negative, or
off + len is out of range.
|
---|
Returns reference to the underlying byte array.
Returns the byte
value in this buffer at the specified
index. The index argument must be greater than or equal to
0
, and less than the length of this buffer.
i | the index of the desired byte value. |
---|
IndexOutOfBoundsException | if index is
negative or greater than or equal to length() .
|
---|
Returns the current capacity. The capacity is the amount of storage available for newly appended bytes, beyond which an allocation will occur.
Clears content of the buffer. The underlying byte array is not resized.
Ensures that the capacity is at least equal to the specified minimum.
If the current capacity is less than the argument, then a new internal
array is allocated with greater capacity. If the required
argument is non-positive, this method takes no action.
required | the minimum required capacity. |
---|
Returns the index within this buffer of the first occurrence of the
specified byte, starting the search at the specified
beginIndex
and finishing at endIndex
.
If no such byte occurs in this buffer within the specified bounds,
-1
is returned.
There is no restriction on the value of beginIndex
and
endIndex
. If beginIndex
is negative,
it has the same effect as if it were zero. If endIndex
is
greater than length()
, it has the same effect as if it were
length()
. If the beginIndex
is greater than
the endIndex
, -1
is returned.
b | the byte to search for. |
---|---|
beginIndex | the index to start the search from. |
endIndex | the index to finish the search at. |
-1
if the byte does
not occur.Returns the index within this buffer of the first occurrence of the
specified byte, starting the search at 0
and finishing
at length()
. If no such byte occurs in this buffer within
those bounds, -1
is returned.
b | the byte to search for. |
---|
-1
if the byte does not occur.Returns true
if this buffer is empty, that is, its
length()
is equal to 0
.
true
if this buffer is empty, false
otherwise.
Returns true
if this buffer is full, that is, its
length()
is equal to its capacity()
.
true
if this buffer is full, false
otherwise.
Returns the length of the buffer (byte count).
Sets the length of the buffer. The new length value is expected to be
less than the current capacity and greater than or equal to
0
.
len | the new length |
---|
IndexOutOfBoundsException | if the
len argument is greater than the current
capacity of the buffer or less than 0 .

Converts the content of this buffer to an array of bytes.
