Constructor Detail

StringBufferCharList

public StringBufferCharList()

Constructor that uses an empty string as the datasource.

StringBufferCharList

public StringBufferCharList(CharList list)

Constructor that copies the specified list.

Parameters:

list - the list to copy, must not be null

Throws:

java.lang.IllegalArgumentException - if the list is null

StringBufferCharList

public StringBufferCharList(java.lang.String str)

Constructor that copies the specified string.

Parameters:

str - the string to copy, must not be null

Throws:

java.lang.IllegalArgumentException - if the string is null

StringBufferCharList

protected StringBufferCharList(java.lang.StringBuffer buf)

Constructor that decorates the specified string buffer.

Parameters:

buf - the string buffer to decorate, must not be null

Throws:

java.lang.IllegalArgumentException - if the string is null

Method Detail

decorate

public static StringBufferCharList decorate(java.lang.StringBuffer buf)

Decorates the specified string buffer with a StringBufferCharList.

The specified buffer is used as the datasource, so changes to one will affect the other.

Parameters:

buf - the string buffer to decorate, must not be null

Returns:

the new StringBufferCharList

Throws:

java.lang.IllegalArgumentException - if the string is null

getChar

public char getChar(int index)

Gets the character at the specified index.

Parameters:

index - the index to retrieve

Returns:

the character at the specified index

size

public int size()

Gets the size of the list, which is the string length.

Returns:

the string length

add

public boolean add(int index,
                   char value)

Adds a primitive value to this list at an index.

Specified by:

add in interface CharList

Overrides:

add in class AbstractCharList

Parameters:

index - the index to add at

value - the value to add to this collection

Returns:

true if this list was modified by this method call

Throws:

java.lang.IndexOutOfBoundsException - if the index is invalid

removeIndex

public char removeIndex(int index)

Removes a primitive value by index from the list.

Parameters:

index - the index to remove from

Returns:

the primitive value previously at this index

Throws:

java.lang.IndexOutOfBoundsException - if the index is invalid

set

public char set(int index,
                char value)

Sets the primitive value at a specified index.

This implementation throws UnsupportedOperationException.

Specified by:

set in interface CharList

Overrides:

set in class AbstractCharList

Parameters:

index - the index to set

value - the value to store

Returns:

the previous value at the index
