simple replacment of '$' with '.' of a binary name would not work,
as '$' is a legal Java Identifier character.
Parameters:
c - A instance of java.lang.Class The canonical name of c. |
| getExpr | | public static String getExpr(String expression, boolean isXml)(Code) | | the "expression" part of a runtime expression, taking the delimiters out. |

Parameters:
expression - a String containing zero or more "${}" expressions
Parameters:
expectedType - the expected type of the interpreted result
Parameters:
fnmapvar - Variable pointing to a function map.
Parameters:
XmlEscape - True if the result should do XML escaping a String representing a call to the EL interpreter. |
| isExpression | | public static boolean isExpression(String token, boolean isXml)(Code) | | Checks if the token is a runtime expression.
In standard JSP syntax, a runtime expression starts with '<%' and
ends with '%>'. When the JSP document is in XML syntax, a runtime
expression starts with '%=' and ends with '%'.
Parameters:
token - The token to be checkedreturn whether the token is a runtime expression or not. |
| isJavaKeyword | | public static boolean isJavaKeyword(String key)(Code) | | Test whether the argument is a Java keyword
|

Parameters:
identifier - Identifier to convert Legal Java identifier corresponding to the given identifier |
| makeJavaPackage | | final public static String makeJavaPackage(String path)(Code) | | Converts the given path to a Java package or fully-qualified class name
Parameters:
path - Path to convert Java package corresponding to the given path |
| makeXmlJavaIdentifier | | final public static String makeXmlJavaIdentifier(String name)(Code) | | Converts the given Xml name to a legal Java identifier. This is
slightly more efficient than makeJavaIdentifier in that we only need
to worry about '.', '-', and ':' in the string. We also assume that
the resultant string is further concatenated with some prefix string
so that we don't have to worry about it being a Java key word.
Parameters:
name - Identifier to convert Legal Java identifier corresponding to the given identifier |
| mangleChar | | final public static String mangleChar(char ch)(Code) | | Mangle the specified character to create a legal Java class name.
|
| nextTemporaryVariableName | | public static String nextTemporaryVariableName()(Code) | | Generates a new temporary variable name.
(not thread-safe)
|
| removeQuotes | | public static char[] removeQuotes(char[] chars)(Code) | | |
| replace | | public static String replace(String name, char replace, String with)(Code) | | Replaces any occurrences of the character replace with the
string with.
|
| resetTemporaryVariableName | | public static void resetTemporaryVariableName()(Code) | | Resets the temporary variable name.
(not thread-safe)
|
| toClass | | public static Class toClass(String type, ClassLoader loader) throws ClassNotFoundException(Code) | | Returns the Class object associated with the class or
interface with the given string name.
The Class object is determined by passing the given string
name to the Class.forName() method, unless the given string
name represents a primitive type, in which case it is converted to a
Class object by appending ".class" to it (e.g., "int.class").
|
| toJavaSourceType | | public static String toJavaSourceType(String type)(Code) | | Class.getName() return arrays in the form "[[[", where et,
the element type can be one of ZBCDFIJS or L;
It is converted into forms that can be understood by javac.
|
| toJavaSourceTypeFromTld | | public static String toJavaSourceTypeFromTld(String type)(Code) | | Handles taking input from TLDs
'java.lang.Object' -> 'java.lang.Object.class'
'int' -> 'int.class'
'void' -> 'Void.TYPE'
'int[]' -> 'int[].class'
Parameters:
type - |
| validateExpressions | | public static void validateExpressions(Mark where, String expressions, Class expectedType, FunctionMapper functionMapper, ErrorDispatcher err) throws JasperException(Code) | | Validates the syntax of all ${} expressions within the given string.
Parameters:
where - the approximate location of the expressions in the JSP page
