Class PGtokenizer
java.lang.Objectpostgresql.util.PGtokenizer
- public class PGtokenizer
- extends java.lang.Object
This class is used to tokenize the text output of postgres.
It's mainly used by the geometric classes, but is useful in parsing any output from custom data types output from postgresql.

PGtokenizer
public PGtokenizer(java.lang.String string, char delim)
- Create a tokeniser.
We could have used StringTokenizer to do this, however, we needed to handle nesting of '(' ')' '[' ']' '<' and '>' as these are used by the geometric data types.
| Method Detail |
tokenize
public int tokenize(java.lang.String string, char delim)
- This resets this tokenizer with a new string and/or delimiter.
getSize
public int getSize()
getToken
public java.lang.String getToken(int n)
tokenizeToken
public PGtokenizer tokenizeToken(int n, char delim)
- This returns a new tokenizer based on one of our tokens.
The geometric datatypes use this to process nested tokens (usually
PGpoint).
remove
public static java.lang.String remove(java.lang.String s, java.lang.String l, java.lang.String t)
- This removes the lead/trailing strings from a string
remove
public void remove(java.lang.String l, java.lang.String t)
- This removes the lead/trailing strings from all tokens
removePara
public static java.lang.String removePara(java.lang.String s)
- Removes ( and ) from the beginning and end of a string
removePara
public void removePara()
- Removes ( and ) from the beginning and end of all tokens
removeBox
public static java.lang.String removeBox(java.lang.String s)
- Removes [ and ] from the beginning and end of a string
removeBox
public void removeBox()
- Removes [ and ] from the beginning and end of all tokens
removeAngle
public static java.lang.String removeAngle(java.lang.String s)
- Removes < and > from the beginning and end of a string
removeAngle
public void removeAngle()
- Removes < and > from the beginning and end of all tokens
