-get
-
-public abstract byte get()
-
- Relative get method. Reads the byte at this buffer's current position, and then increments the position.
-
- Returns:
- The byte at the buffer's current position
- Throws:
- BufferUnderflowException - If the buffer's current position is not smaller than its limit
-
-put
-
-public abstract ByteBuffer put(byte b)
-
- Relative put method (optional operation).
-
- Writes the given byte into this buffer at the current position, and then increments the position.
-
- Parameters:
- b - The byte to be written
- Returns:
- This buffer
- Throws:
- BufferOverflowException - If this buffer's current position is not smaller than its limit
- ReadOnlyBufferException - If this buffer is read-only
-
-get
-
-public abstract byte get(int index)
-
- Absolute get method. Reads the byte at the given index.
-
- Parameters:
- index - The index from which the byte will be read
- Returns:
- The byte at the given index
- Throws:
- IndexOutOfBoundsException - If index is negative or not smaller than the buffer's limit
-
-put
-
-public abstract ByteBuffer put(int index,
- byte b)
-
- Absolute put method (optional operation).
-
- Writes the given byte into this buffer at the given index.
-
- Parameters:
- index - The index at which the byte will be written
- b - The byte value to be written
- Returns:
- This buffer
- Throws:
- IndexOutOfBoundsException - If index is negative or not smaller than the buffer's limit
- ReadOnlyBufferException - If this buffer is read-only
-
-get
-
-public ByteBuffer get(byte[] dst,
- int offset,
- int length)
-
- Relative bulk get method.
-
- This method transfers bytes from this buffer into the given destination array. If there are fewer bytes remaining in the buffer than are required to satisfy the request, that is, if length > remaining(), then no bytes are transferred and a BufferUnderflowException is thrown.
-
- Otherwise, this method copies length bytes from this buffer into the given array, starting at the current position of this buffer and at the given offset in the array. The position of this buffer is then incremented by length.
-
- In other words, an invocation of this method of the form src.get(dst, off, len) has exactly the same effect as the loop
-
- for (int i = off; i < off + len; i++)
- dst[i] = src.get();
-
- except that it first checks that there are sufficient bytes in this buffer and it is potentially much more efficient.
-
- Parameters:
- dst - The array into which bytes are to be written
- offset - The offset within the array of the first byte to be written; must be non-negative and no larger than dst.length
- length - The maximum number of bytes to be written to the given array; must be non-negative and no larger than dst.length - offset
- Returns:
- This buffer
- Throws:
- BufferUnderflowException - If there are fewer than length bytes remaining in this buffer
- IndexOutOfBoundsException - If the preconditions on the offset and length parameters do not hold
-
-get
-
-public ByteBuffer get(byte[] dst)
-
- Relative bulk get method.
-
- This method transfers bytes from this buffer into the given destination array. An invocation of this method of the form src.get(a) behaves in exactly the same way as the invocation
-
- src.get(a, 0, a.length)
-
- Returns:
- This buffer
- Throws:
- BufferUnderflowException - If there are fewer than length bytes remaining in this buffer
-
-put
-
-public ByteBuffer put(ByteBuffer src)
-
- Relative bulk put method (optional operation).
-
- This method transfers the bytes remaining in the given source buffer into this buffer. If there are more bytes remaining in the source buffer than in this buffer, that is, if src.remaining() > remaining(), then no bytes are transferred and a BufferOverflowException is thrown.
-
- Otherwise, this method copies n = src.remaining() bytes from the given buffer into this buffer, starting at each buffer's current position. The positions of both buffers are then incremented by n.
-
- In other words, an invocation of this method of the form dst.put(src) has exactly the same effect as the loop
-
- while (src.hasRemaining())
- dst.put(src.get());
-
- except that it first checks that there is sufficient space in this buffer and it is potentially much more efficient.
-
- Parameters:
- src - The source buffer from which bytes are to be read; must not be this buffer
- Returns:
- This buffer
- Throws:
- BufferOverflowException - If there is insufficient space in this buffer for the remaining bytes in the source buffer
- IllegalArgumentException - If the source buffer is this buffer
- ReadOnlyBufferException - If this buffer is read-only
-
-put
-
-public ByteBuffer put(byte[] src,
- int offset,
- int length)
-
- Relative bulk put method (optional operation).
-
- This method transfers bytes into this buffer from the given source array. If there are more bytes to be copied from the array than remain in this buffer, that is, if length > remaining(), then no bytes are transferred and a BufferOverflowException is thrown.
-
- Otherwise, this method copies length bytes from the given array into this buffer, starting at the given offset in the array and at the current position of this buffer. The position of this buffer is then incremented by length.
-
- In other words, an invocation of this method of the form dst.put(src, off, len) has exactly the same effect as the loop
-
- for (int i = off; i < off + len; i++)
- dst.put(a[i]);
-
- except that it first checks that there is sufficient space in this buffer and it is potentially much more efficient.
-
- Parameters:
- src - The array from which bytes are to be read
- offset - The offset within the array of the first byte to be read; must be non-negative and no larger than array.length
- length - The number of bytes to be read from the given array; must be non-negative and no larger than array.length - offset
- Returns:
- This buffer
- Throws:
- BufferOverflowException - If there is insufficient space in this buffer
- IndexOutOfBoundsException - If the preconditions on the offset and length parameters do not hold
- ReadOnlyBufferException - If this buffer is read-only
-
-put
-
-public final ByteBuffer put(byte[] src)
-
- Relative bulk put method (optional operation).
-
- This method transfers the entire content of the given source byte array into this buffer. An invocation of this method of the form dst.put(a) behaves in exactly the same way as the invocation
