Method Detail

asReadOnlyBufferback to summary
public CharBuffer asReadOnlyBuffer()

Implements abstract java.nio.CharBuffer.asReadOnlyBuffer.

Doc from java.nio.CharBuffer.asReadOnlyBuffer.

Creates a new, read-only char 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, mark values, and byte order 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.

compactback to summary
public CharBuffer compact()

Implements abstract java.nio.CharBuffer.compact.

Doc from java.nio.CharBuffer.compact.

Compacts this buffer  (optional operation).

The chars between the buffer's current position and its limit, if any, are copied to the beginning of the buffer. That is, the char at index p = position() is copied to index zero, the char at index p + 1 is copied to index one, and so forth until the char 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 chars copied, rather than to zero, so that an invocation of this method can be followed immediately by an invocation of another relative put method.

duplicateback to summary
public CharBuffer duplicate()

Implements abstract java.nio.CharBuffer.duplicate.

Doc from java.nio.CharBuffer.duplicate.

Creates a new char 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, mark values, and byte order 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.

getback to summary
public char get()

Implements abstract java.nio.CharBuffer.get.

Doc from java.nio.CharBuffer.get.

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

getback to summary
public char get(int i)

Implements abstract java.nio.CharBuffer.get.

Doc from java.nio.CharBuffer.get.

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

getUncheckedback to summary
pack-priv char getUnchecked(int i)

Implements abstract java.nio.CharBuffer.getUnchecked.

Doc from java.nio.CharBuffer.getUnchecked.

Absolute get method. Reads the char at the given index without any validation of the index.

public boolean isDirect()

Implements abstract java.nio.CharBuffer.isDirect.

Doc from java.nio.CharBuffer.isDirect.

Tells whether or not this char buffer is direct.

isReadOnlyback to summary
public boolean isReadOnly()

Implements abstract java.nio.Buffer.isReadOnly.

Doc from java.nio.Buffer.isReadOnly.

Tells whether or not this buffer is read-only.

private int ix(int i)
orderback to summary
public ByteOrder order()

Implements abstract java.nio.CharBuffer.order.

Doc from java.nio.CharBuffer.order.

Retrieves this buffer's byte order.

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

putback to summary
public CharBuffer put(char x)

Implements abstract java.nio.CharBuffer.put.

Doc from java.nio.CharBuffer.put.

Relative put method  (optional operation).

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

putback to summary
public CharBuffer put(int i, char x)

Implements abstract java.nio.CharBuffer.put.

Doc from java.nio.CharBuffer.put.

Absolute put method  (optional operation).

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

scaleShiftsback to summary
pack-priv int scaleShifts()

Overrides java.nio.CharBuffer.scaleShifts.

Doc from java.nio.Buffer.scaleShifts.

sliceback to summary
public CharBuffer slice()

Implements abstract java.nio.CharBuffer.slice.

Doc from java.nio.CharBuffer.slice.

Creates a new char 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 chars remaining in this buffer, its mark will be undefined, and its byte order will be identical to that 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.

sliceback to summary
public CharBuffer slice(int index, int length)

Implements abstract java.nio.CharBuffer.slice.

Doc from java.nio.CharBuffer.slice.

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

The content of the new buffer will start at position index in this buffer, and will contain length elements. 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 length, its mark will be undefined, and its byte order will be identical to that 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.

Implements abstract java.nio.CharBuffer.subSequence.

Implements java.lang.CharSequence.subSequence.

Doc from java.nio.CharBuffer.subSequence.

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, its limit will be position() + end, and its byte order will be identical to that 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.
