Method Details
-
isLiteral
public boolean isLiteral()If it's literal text- Returns:
- true if the String is literal (doesn't contain
#{..}or${..})
-
apply
Return an instance ofthisthat is applicable given the ELContext and ExpressionFactory state.- Parameters:
factory- the ExpressionFactory to usectx- the ELContext to use- Returns:
- an ELText instance
-
write
Allow this instance to write to the passed Writer, given the ELContext state- Parameters:
out- Writer to write toctx- current ELContext state- Throws:
jakarta.el.ELExceptionIOException
-
writeText
public void writeText(ResponseWriter out, jakarta.el.ELContext ctx) throws jakarta.el.ELException, IOException - Throws:
jakarta.el.ELExceptionIOException
-
toString
Evaluates the ELText to a String- Parameters:
ctx- current ELContext state- Returns:
- the evaluated String
- Throws:
jakarta.el.ELException
-
toString
-
isLiteral
Parses the passed string to determine if it's literal or not- Parameters:
in- input String- Returns:
- true if the String is literal (doesn't contain
#{..}or${..})
-
parse
- Throws:
jakarta.el.ELException
-
parse
Factory method for creating an unvalidated ELText instance. NOTE: All expressions in the passed String are treated asLocationValueExpression.- Parameters:
in- String to parselocation- The location- Returns:
- ELText instance that knows if the String was literal or not
- Throws:
jakarta.el.ELException
-
parseAllowEmptyString
public static ELText parseAllowEmptyString(String in, Location location) throws jakarta.el.ELException - Throws:
jakarta.el.ELException
-
parseAsString
public static String parseAsString(jakarta.el.ExpressionFactory fact, jakarta.el.ELContext ctx, String in) throws jakarta.el.ELException - Throws:
jakarta.el.ELException
-
parse
public static ELText parse(jakarta.el.ExpressionFactory fact, jakarta.el.ELContext ctx, String in) throws jakarta.el.ELException - Throws:
jakarta.el.ELException
-
parse
public static ELText parse(jakarta.el.ExpressionFactory fact, jakarta.el.ELContext ctx, String in, Location location) throws jakarta.el.ELException Factory method for creating a validated ELText instance. When an Expression is hit, it will use the ExpressionFactory to create a ValueExpression instance, resolving any functions at that time.Variables and properties will not be evaluated.
- Parameters:
fact- ExpressionFactory to usectx- ELContext to validate againstin- String to parselocation- The location- Returns:
- ELText that can be re-applied later
- Throws:
jakarta.el.ELException
-
parseAsArray
- Throws:
jakarta.el.ELException
-
parseAsArray
public static ELText[] parseAsArray(jakarta.el.ExpressionFactory fact, jakarta.el.ELContext ctx, String in, Location location) throws jakarta.el.ELException - Throws:
jakarta.el.ELException
-
isLiteral
public static boolean isLiteral(jakarta.el.ExpressionFactory fact, jakarta.el.ELContext ctx, String in) throws jakarta.el.ELException - Throws:
jakarta.el.ELException
