contentsAsArray() |
BigDecimal |
contentsAsDecimal()
Convenience method for converting contents of the buffer
into a
BigDecimal . |

contentsAsDouble()
Convenience method for converting contents of the buffer
into a Double value.
|
String |
contentsAsString() |
char[] |
emptyAndGetCurrentSegment() |
void |
ensureNotShared()
Method called to make sure that buffer is not using shared input
buffer; if it is, it will copy such contents to private buffer.
|
char[] |
expandCurrentSegment()
Method called to expand size of the current segment, to
accommodate for more contiguous content.
|
char[] |
expandCurrentSegment(int minSize)
Method called to expand size of the current segment, to
accommodate for more contiguous content.

getTextBuffer() |
int |
getTextOffset() |
boolean |
hasTextAsCharacters()
Method that can be used to check whether textual contents can
be efficiently accessed using
getTextBuffer() . |
void |
releaseBuffers()
Method called to indicate that the underlying buffers should now
be recycled if they haven't yet been recycled.
|
void |
resetWithCopy(char[] buf,
int start,
int len) |
void |
resetWithEmpty()
Method called to clear out any content text buffer may have, and
initializes buffer to use non-shared data.
|
void |
resetWithShared(char[] buf,
int start,
int len)
Method called to initialize the buffer with a shared copy of data;
this means that buffer will just have pointers to actual data.

Note: calling this method may not be as efficient as calling
contentsAsString() , since it's not guaranteed that resulting
String is cached. |
