| deleteCharAt0 | | final void deleteCharAt0(int location)(Code) | | |
| ensureCapacity | | public void ensureCapacity(int min)(Code) | | Ensures that this object has a minimum capacity available before
requiring the internal buffer to be enlarged. The general policy of this
method is that if the minimumCapacity is larger than the
current
AbstractStringBuilder.capacity() , then the capacity will be increased to the
largest value of either the minimumCapacity or the current
capacity multiplied by two plus two. Although this is the general policy,
there is no guarantee that the capacity will change.
Parameters:
min - The new minimum capacity to set. |
| getChars | | public void getChars(int start, int end, char[] dest, int destStart)(Code) | | Copies the requested sequence of characters to be copied to the
char[] passed.
Parameters:
start - The inclusive start index of the characters to copy from thisobject.
Parameters:
end - The exclusive end index of the characters to copy from thisobject.
Parameters:
dest - The char[] to copy the characters to.
Parameters:
destStart - The inclusive start index of the dest parameterto begin copying to.
throws:
IndexOutOfBoundsException - if the start is negative, thedestStart is negative, the startis greater than end, the endis greater than the current AbstractStringBuilder.length() ordestStart + end - begin is greater thandest.length. |
