Interface Clob
This interface contains methods for accessing a SQL CLOB (Character
Large OBject) type.
InputStream | getAsciiStream() - This method returns a byte stream that reads the contents of the
CLOB as a series of ASCII bytes.
|
Reader | getCharacterStream() - This method returns a character stream that reads the contents of the
CLOB.
|
String | getSubString(long pos, int length) - This method returns the specified portion of the CLOB as a
String .
|
long | length() - This method returns the number of characters in the CLOB.
|
long | position(String searchstr, long start) - This method returns the index into the CLOB of the first occurrence of
the specified character pattern (supplied by the caller as a
String ).
|
long | position(Clob searchstr, long start) - This method returns the index into the CLOB of the first occurrence of
the specified character pattern (supplied by the caller as a
Clob ).
|
OutputStream | setAsciiStream(long pos)
|
Writer | setCharacterStream(long pos)
|
int | setString(long pos, String str)
|
int | setString(long pos, String str, int offset, int len)
|
void | truncate(long len)
|
getAsciiStream
public InputStream getAsciiStream()
throws SQLException
This method returns a byte stream that reads the contents of the
CLOB as a series of ASCII bytes.
- A stream to read the CLOB's contents.
getCharacterStream
public Reader getCharacterStream()
throws SQLException
This method returns a character stream that reads the contents of the
CLOB.
- A character stream to read the CLOB's contents.
getSubString
public String getSubString(long pos,
int length)
throws SQLException
This method returns the specified portion of the CLOB as a
String
.
length
- The requested number of characters to return.
- The requested CLOB section, as a
String
.
length
public long length()
throws SQLException
This method returns the number of characters in the CLOB.
- The number of characters in the CLOB.
position
public long position(String searchstr,
long start)
throws SQLException
This method returns the index into the CLOB of the first occurrence of
the specified character pattern (supplied by the caller as a
String
). The search begins at the specified index.
searchstr
- The character pattern to search for, passed as a
String
.
- The index at which the pattern was found (indexes start at 1),
or -1 if the pattern was not found.
position
public long position(Clob searchstr,
long start)
throws SQLException
This method returns the index into the CLOB of the first occurrence of
the specified character pattern (supplied by the caller as a
Clob
). The search begins at the specified index.
searchstr
- The character pattern to search for, passed as a
Clob
.
- The index at which the pattern was found (indexes start at 1),
or -1 if the pattern was not found.
