Constructor Detail

SimpleStringBuffer

public SimpleStringBuffer()

SimpleStringBuffer

public SimpleStringBuffer(int length)

SimpleStringBuffer

public SimpleStringBuffer(java.lang.String str)

Method Detail

length

public int length()

Returns the length (character count) of this string buffer.

Returns:

the number of characters in this string buffer.

capacity

public int capacity()

Returns the current capacity of the String buffer. The capacity is the amount of storage available for newly inserted characters; beyond which an allocation will occur.

Returns:

the current capacity of this string buffer.

ensureCapacity

public void ensureCapacity(int minimumCapacity)

Ensures that the capacity of the buffer is at least equal to the specified minimum. If the current capacity of this string buffer is less than the argument, then a new internal buffer is allocated with greater capacity. The new capacity is the larger of:

• The minimumCapacity argument.
• Twice the old capacity, plus 2.

If the minimumCapacity argument is nonpositive, this method takes no action and simply returns.

Parameters:

minimumCapacity - the minimum desired capacity.

setLength

public void setLength(int newLength)

charAt

public char charAt(int index)

getChars

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

setCharAt

public void setCharAt(int index,
                      char ch)

insert

public SimpleStringBuffer insert(int offset,

delete

public SimpleStringBuffer delete(int start,
                                 int end)

Removes the characters in a substring of this SimpleStringBuffer. The substring begins at the specified start and extends to the character at index end - 1 or to the end of the SimpleStringBuffer if no such character exists. If start is equal to end, no changes are made.

Parameters:

start - - the beginning index, inclusive

end - - the ending index, exclusive

Returns:

This simple string buffer

Throws:

java.lang.StringIndexOutOfBoundsException - - if start is negative, greater than length(), or greater than end.

deleteCharAt

public SimpleStringBuffer deleteCharAt(int index)

Removes the character at the specified position in this SimpleStringBuffer (shortening the SimpleStringBuffer by one character).

Parameters:

index - - index of the character to remove

Returns:

This simple string buffer

Throws:

java.lang.StringIndexOutOfBoundsException - - if the index is negative or greater than or equal to length().

replace

public SimpleStringBuffer replace(int start,
                                  int end,
                                  java.lang.String str)

Replaces the characters in a substring of this SimpleStringBuffer with characters in the specified String. The substring begins at the specified start and extends to the character at index end - 1 or to the end of the SimpleStringBuffer if no such character exists. First the characters in the substring are removed and then the specified String is inserted at start. (The SimpleStringBuffer will be lengthened to accommodate the specified String if necessary.)

Parameters:

start - - the beginning index, inclusive

end - - the ending index, exclusive

str - - string that will replace previous contents

Returns:

This simple string buffer

Throws:

java.lang.StringIndexOutOfBoundsException - - if start is negative, greater than length(), or greater than end.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getValue

public char[] getValue()
