pattern
protected Pattern pattern
patternCompiled
protected boolean patternCompiled
ignoringCase
protected boolean ignoringCase
escapeChar
protected char escapeChar
getEscapeChar
public char getEscapeChar()
This method will return an escape character for the like
clause. The escape character will eventually end up in the
query as ...(t0.foo LIKE ? {escape '|'}) where the
pipe symbol is the escape character.
Note that having no escape character is represented as
the character 0.
setEscapeChar
public void setEscapeChar(char value)
This method allows the setting of the escape character.
The escape character can be used in a LIKE clause. The
character 0 signifies no escape character. The escape
characyer '?' is disallowed.
matchPattern
protected boolean matchPattern(String string)
getPattern
protected Pattern getPattern()
jjtAddChild
public void jjtAddChild(Node n,
int i)
- Description copied from interface:
Node
- This method tells the node to add its argument to the node's
list of children.
- Specified by:
jjtAddChild
in interface Node
- Overrides:

in class SimpleNode
