| Field Summary | |
| String | filename
The CVS file to read. | | protected Hashtable<String, Integer> | name2pos
The CVS file header, which contains the column names. | | protected Vector<Vector<String>> | rows
The content of the CVS file body (the records or rows).
Each entry in rows represents a line or record in the CVS body.
Each line is represented by a Vector of values. |
| Constructor Summary | |
| public | CVSReader(String filename)
Constructor for the CVS Reader. |
| Method Summary | |
| Vector<Vector<String>> | decodeBody(StringTokenizer mtok)
Parses the body text of a CVS file.
Each row (line of text) in the body is a record whose fields are represented by a list of
komma-separated, possibly quoted, elements.
This routime converted the line into a Vector consisting of these elements.
Parameters:
tok - A tokenenized list of strings (lines) that make up the body text. | | Hashtable<String, Integer> | decodeHeader(String line)
Converts a CVS Header line into a hashtable of header elements. | | public String | getElement(int row, int col)
Returns the element at the given row and column. | | public String | getElement(int row, String colname)
Returns the element at the given row and with the given column name. | | public String | loadFile(String filename)
Reads the content of a file. | | public void | readCVS(String filename)
Reads the contents of a CVS file and extracts the header and body content. | | public int | size()
Returns the number of rows in the CVS body. |
| name2pos | | protected Hashtable<String, Integer> name2pos(Code) | | The CVS file header, which contains the column names.
The header is represented by a Hashtable of name-values
where name is a column name and value the index of that column.
|
| rows | | protected Vector<Vector<String>> rows(Code) | | The content of the CVS file body (the records or rows).
Each entry in rows represents a line or record in the CVS body.
Each line is represented by a Vector of values. The position of those
values matches with teh columns from the header.

komma-separated, possibly quoted, elements.
This routime converted the line into a Vector consisting of these elements.
Parameters:
tok - A tokenenized list of strings (lines) that make up the body text. a Vector containing, for each line in the CVS body, a list of elements. |
| decodeHeader | | Hashtable<String, Integer> decodeHeader(String line)(Code) | | Converts a CVS Header line into a hashtable of header elements.
Parameters:
line - the headerline to parse (should exists of elements seperated by commas) a Hashtable containing the header values with theirpostition in the header |
| getElement | | public String getElement(int row, int col)(Code) | | Returns the element at the given row and column.
Parameters:
row - the element row

col - the element column the element as a String. |
| getElement | | public String getElement(int row, String colname)(Code) | | Returns the element at the given row and with the given column name.
Parameters:
row - the element row

colname - the element columnname the element as a String. |
| loadFile | | public String loadFile(String filename)(Code) | | Reads the content of a file.
Parameters:
filename - path and name of the file to read the content of the file as a string |
| readCVS | | public void readCVS(String filename)(Code) | | Reads the contents of a CVS file and extracts the header and body content.
