Method Detail
-
getEnclosingClass
public CtClass getEnclosingClass()
Returns the class that declares the method enclosing this expression.- Since:
- 3.7
-
where
public CtBehavior where()
Returns the constructor or method containing the expression.
-
mayThrow
public CtClass[] mayThrow()
Returns the list of exceptions that the expression may throw. This list includes both the exceptions that the try-catch statements including the expression can catch and the exceptions that the throws declaration allows the method to throw.
-
indexOfBytecode
public int indexOfBytecode()
Returns the index of the bytecode corresponding to the expression. It is the index into the byte array containing the Java bytecode that implements the method.
-
getLineNumber
public int getLineNumber()
Returns the line number of the source line containing the expression.- Returns:
- -1 if this information is not available.
-
getFileName
public java.lang.String getFileName()
Returns the source file containing the expression.- Returns:
- null if this information is not available.
-
replace
public abstract void replace(java.lang.String statement) throws CannotCompileException
Replaces this expression with the bytecode derived from the given source text.- Parameters:
statement
- a Java statement except try-catch.- Throws:
CannotCompileException
-
replace
public void replace(java.lang.String statement, ExprEditor recursive) throws CannotCompileException
Replaces this expression with the bytecode derived from the given source text andExprEditor
.- Parameters:
statement
- a Java statement except try-catch.recursive
- if not null, the substituted bytecode is recursively processed by the givenExprEditor
.- Throws:
CannotCompileException
- Since:
- 3.1
