Method Detail

slice

public CharBuffer slice()

Description copied from class: CharBuffer

Creates a new character buffer whose content is a shared subsequence of this buffer's content.

The content of the new buffer will start at this buffer's current position. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.

The new buffer's position will be zero, its capacity and its limit will be the number of characters remaining in this buffer, and its mark will be undefined. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.

Overrides:

slice in class ByteBufferAsCharBufferL

duplicate

public CharBuffer duplicate()

Description copied from class: CharBuffer

Creates a new character buffer that shares this buffer's content.

The content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.

The new buffer's capacity, limit, position, and mark values will be identical to those of this buffer. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.

Overrides:

duplicate in class ByteBufferAsCharBufferL

asReadOnlyBuffer

public CharBuffer asReadOnlyBuffer()

Description copied from class: CharBuffer

Creates a new, read-only character buffer that shares this buffer's content.

The content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer; the new buffer itself, however, will be read-only and will not allow the shared content to be modified. The two buffers' position, limit, and mark values will be independent.

The new buffer's capacity, limit, position, and mark values will be identical to those of this buffer.

If this buffer is itself read-only then this method behaves in exactly the same way as the duplicate method.

Overrides:

asReadOnlyBuffer in class ByteBufferAsCharBufferL

put

public CharBuffer put(char x)

Description copied from class: CharBuffer

Relative put method (optional operation).

Writes the given character into this buffer at the current position, and then increments the position.

Overrides:

put in class ByteBufferAsCharBufferL

put

public CharBuffer put(int i,
                      char x)

Description copied from class: CharBuffer

Absolute put method (optional operation).

Writes the given character into this buffer at the given index.

Overrides:

put in class ByteBufferAsCharBufferL

compact

public CharBuffer compact()

Description copied from class: CharBuffer

Compacts this buffer (optional operation).

The characters between the buffer's current position and its limit, if any, are copied to the beginning of the buffer. That is, the character at index p = position() is copied to index zero, the character at index p + 1 is copied to index one, and so forth until the character at index limit() - 1 is copied to index n = limit() - 1 - p. The buffer's position is then set to n+1 and its limit is set to its capacity. The mark, if defined, is discarded.

The buffer's position is set to the number of characters copied, rather than to zero, so that an invocation of this method can be followed immediately by an invocation of another relative put method.

Overrides:

compact in class ByteBufferAsCharBufferL

isDirect

public boolean isDirect()

Description copied from class: CharBuffer

Tells whether or not this character buffer is direct.

Overrides:

isDirect in class ByteBufferAsCharBufferL

isReadOnly

public boolean isReadOnly()

Description copied from class: Buffer

Tells whether or not this buffer is read-only.

Overrides:

isReadOnly in class ByteBufferAsCharBufferL

toString

public String toString(int start,
                       int end)

Overrides:

toString in class ByteBufferAsCharBufferL

subSequence

public CharSequence subSequence(int start,
                                int end)

Description copied from class: CharBuffer

Creates a new character buffer that represents the specified subsequence of this buffer, relative to the current position.

The new buffer will share this buffer's content; that is, if the content of this buffer is mutable then modifications to one buffer will cause the other to be modified. The new buffer's capacity will be that of this buffer, its position will be position() + start, and its limit will be position() + end. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.

Specified by:

subSequence in interface CharSequence

Overrides:

subSequence in class ByteBufferAsCharBufferL

order

public ByteOrder order()

Description copied from class: CharBuffer

Retrieves this buffer's byte order.

The byte order of a character buffer created by allocation or by wrapping an existing char array is the native order of the underlying hardware. The byte order of a character buffer created as a view of a byte buffer is that of the byte buffer at the moment that the view is created.

Overrides:

order in class ByteBufferAsCharBufferL

ix

protected int ix(int i)

get

public char get()

Description copied from class: CharBuffer

Relative get method. Reads the character at this buffer's current position, and then increments the position.

Specified by:

get in class CharBuffer

Returns:

The character at the buffer's current position

get

public char get(int i)

Description copied from class: CharBuffer

Absolute get method. Reads the character at the given index.

Specified by:

get in class CharBuffer

Parameters:

i - The index from which the character will be read

Returns:

The character at the given index
