Example 11 with SignatureVisitor

use of org.objectweb.asm.signature.SignatureVisitor in project cdap by caskdata.

the class Signatures method getMethodSignature.

/**
   * Generates signature for the given method.
   *
   * @param method Method that needs signature to be generated
   * @param returnType the {@link TypeToken} of the return type
   * @param argTypes List of {@link TypeToken} that matches with the number of arguments in the given method.
   *              For a given method argument, if the corresponding {@link TypeToken} is non-null, it will be
   *              used to generate the type parameter in the signature, otherwise, the one in the method will be used.
   *              It's useful if the method is parameterized so that parameterize type information can be passed
   *              through the type tokens.
   * @return A method signature string
