isLiteral
public boolean isLiteral()
If it's literal text- Returns:
- true if the String is literal (doesn't contain
#{..}
or${..}
)
-
apply
public ELText apply(jakarta.el.ExpressionFactory factory, jakarta.el.ELContext ctx)
Return an instance ofthis
that is applicable given the ELContext and ExpressionFactory state.- Parameters:
factory
- the ExpressionFactory to usectx
- the ELContext to use- Returns:
- an ELText instance
-
write
public void write(Writer out, jakarta.el.ELContext ctx) throws jakarta.el.ELException, IOException
Allow this instance to write to the passed Writer, given the ELContext state- Parameters:
out
- Writer to write toctx
- current ELContext state- Throws:
jakarta.el.ELException
- when an EL exception occursIOException
- when an I/O exception occurs
-
writeText
public void writeText(ResponseWriter out, jakarta.el.ELContext ctx) throws jakarta.el.ELException, IOException
- Throws:
jakarta.el.ELException
IOException
-
toString
public String toString(jakarta.el.ELContext ctx) throws jakarta.el.ELException
Evaluates the ELText to a String- Parameters:
ctx
- current ELContext state- Returns:
- the evaluated String
- Throws:
jakarta.el.ELException
- when an EL exception occurs
-
isLiteral
public static boolean isLiteral(String in)
Parses the passed string to determine if it's literal or not- Parameters:
in
- input String- Returns:
- true if the String is literal (doesn't contain
#{..}
or${..}
)
-
parse
public static ELText parse(String in) throws jakarta.el.ELException
Factory method for creating an unvalidated ELText instance. NOTE: All expressions in the passed String are treated asELText.LiteralValueExpression
, with one exception: composite component expressions. These are treated as ContextualCompositeValueExpressions.- Parameters:
in
- String to parse- Returns:
- ELText instance that knows if the String was literal or not
- Throws:
jakarta.el.ELException
- when an EL exception occurs
-
parse
public static ELText parse(String in, String alias) 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, String alias) 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 parsealias
- the alias- Returns:
- ELText that can be re-applied later
- Throws:
jakarta.el.ELException
- when an EL exception occurs
