recordReturnType
public int recordReturnType(CtClass type, String castName, String resultName, SymbolTable tbl) throws CompileError
Makes a cast to the return type ($r) available. It also enables $_.If the return type is void, ($r) does nothing. The type of $_ is java.lang.Object.
- Parameters:
resultName
- null if $_ is not used.- Returns:
- -1 or the variable index assigned to $_.
- Throws:
CompileError
-
recordType
public void recordType(CtClass t)
Makes $type available.
-
recordParams
public int recordParams(CtClass[] params, boolean isStatic, String prefix, String paramVarName, String paramsName, SymbolTable tbl) throws CompileError
Makes method parameters $0, $1, ..., $args, $$, and $class available. $0 is equivalent to THIS if the method is not static. Otherwise, if the method is static, then $0 is not available.- Throws:
CompileError
-
recordParams

Makes method parameters $0, $1, ..., $args, $$, and $class available. $0 is available only if use0 is true. It might not be equivalent to THIS.- Parameters:
params
- the parameter types (the types of $1, $2, ..)prefix
- it must be "$" (the first letter of $0, $1, ...)paramVarName
- it must be "$args"paramsName
- it must be "$$"use0
- true if $0 is used.paramBase
- the register number of $0 (use0 is true) or $1 (otherwise).target
- the class of $0. If use0 is false, target can be null. The value of "target" is also used as the name of the type represented by $class.isStatic
- true if the method in which the compiled bytecode is embedded is static.- Throws:
CompileError
-
recordVariable
