Method Detail

length

int length()

Get length of string, in code units (not characters). In contract, size() returns the number of 16-bit code points.

Specified by:

length in interface CharSequence

charAt

char charAt(int index)

The index is in terms of code units.

Specified by:

charAt in interface CharSequence

getChars

void getChars(int srcBegin,
              int srcEnd,
              char[] dst,
              int dstBegin)

Copy characters into a destination buffer. Same interface as java.lang.String's getChars.

Parameters:

srcBegin - source start position, in 16-bit code units.

srcEnd - source end position, in 16-bit code units.

dst - destination

dstBegin - index (in code units) in dst array

setCharAt

void setCharAt(int index,
               char ch)

setCharacterAt

void setCharacterAt(int index,
                    int ch)

writeTo

void writeTo(int start,
             int count,
             Appendable dest)
      throws IOException

Append a specified subsequence to an Appendable. An allowable implementation is: dest.append(this, start, start+count). Hence implementors of Appendable should avoid calling writeTo - though they can call getChars.

Throws:

IOException

writeTo

void writeTo(Appendable dest)
      throws IOException

Throws:

IOException

toString

String toString()

Specified by:

toString in interface CharSequence

Overrides:

toString in class Object

isEmpty

boolean isEmpty()

Description copied from interface: Sequence

True is this sequence contains no elements.

Specified by:

isEmpty in interface Collection<Char>

Specified by:

isEmpty in interface List<Char>

Specified by:

isEmpty in interface Sequence<Char>
