XStringForChars
public XStringForChars(char[] val,
int start,
int length)
- Construct a XNodeSet object.
- Parameters:
val
- FastStringBuffer object this will wrap, must be non-null.start
- The start position in the array.length
- The number of characters to read from the array.
fsb
public FastStringBuffer fsb()
- Cast result object to a string.
- Returns:
- The string this wraps or the empty string if null
appendToFsb
public void appendToFsb(FastStringBuffer fsb)
- Cast result object to a string.
- Returns:
- The string this wraps or the empty string if null
- Overrides:
- appendToFsb in class XObject
hasString
public boolean hasString()
- Tell if this object contains a java String object.
- Returns:
- true if this XMLString can return a string without creating one.
- Overrides:
- hasString in class XString
str
public java.lang.String str()
- Cast result object to a string.
- Returns:
- The string this wraps or the empty string if null
- Overrides:
- str in class XString
object
public java.lang.Object object()
- Since this object is incomplete without the length and the offset, we
have to convert to a string when this function is called.
- Returns:
- The java String representation of this object.
- Overrides:
- object in class XObject
dispatchCharactersEvents
public void dispatchCharactersEvents(ContentHandler ch)
throws SAXException
- Directly call the
characters method on the passed ContentHandler for the
string-value. Multiple calls to the
ContentHandler's characters methods may well occur for a single call to
this method.
- Parameters:
ch
- A non-null reference to a ContentHandler.- Throws:
- SAXException -
- Overrides:
- dispatchCharactersEvents in class XString
dispatchAsComment
public void dispatchAsComment(LexicalHandler lh)
throws SAXException
- Directly call the
comment method on the passed LexicalHandler for the
string-value.
- Parameters:
lh
- A non-null reference to a LexicalHandler.- Throws:
- SAXException -
- Overrides:
- dispatchAsComment in class XString
length
public int length()
- Returns the length of this string.
- Returns:
- the length of the sequence of characters represented by this
object.
- Overrides:
- length in class XString
charAt
public char charAt(int index)
- Returns the character at the specified index. An index ranges
from
0
to length() - 1
. The first character
of the sequence is at index 0
, the next at index
1
, and so on, as for array indexing.
- Parameters:
index
- the index of the character.- Returns:
- the character at the specified index of this string.
The first character is at index
0
. - Throws:
- java.lang.IndexOutOfBoundsException - if the
index
argument is negative or not less than the length of this
string. - Overrides:
- charAt in class XString
getChars
public void getChars(int srcBegin,
int srcEnd,
char[] dst,
int dstBegin)
- Copies characters from this string into the destination character
array.
- Parameters:
srcBegin
- index of the first character in the string
to copy.srcEnd
- index after the last character in the string
to copy.dst
- the destination array.dstBegin
- the start offset in the destination array.- Throws:
- java.lang.IndexOutOfBoundsException - If any of the following
is true:
srcBegin
is negative.
srcBegin
is greater than srcEnd
srcEnd
is greater than the length of this
string
dstBegin
is negative
dstBegin+(srcEnd-srcBegin)
is larger than
dst.length
- java.lang.NullPointerException - if
dst
is null
- Overrides:
- getChars in class XString
