  - CheckSignatureAdapter
```
public CheckSignatureAdapter(int type,
                     SignatureVisitor sv)
```
    Creates a new CheckSignatureAdapter object. Subclasses must not use this constructor. Instead, they must use the CheckSignatureAdapter(int, int, SignatureVisitor) version.
    
    Parameters:
    type - the type of signature to be checked. See CLASS_SIGNATURE, METHOD_SIGNATURE and TYPE_SIGNATURE.
    sv - the visitor to which this adapter must delegate calls. May be null.
  - CheckSignatureAdapter
```
protected CheckSignatureAdapter(int api,
                     int type,
                     SignatureVisitor sv)
```
    Creates a new CheckSignatureAdapter object.
    
    Parameters:
    api - the ASM API version implemented by this visitor. Must be one of Opcodes.ASM4 or Opcodes.ASM5.
    type - the type of signature to be checked. See CLASS_SIGNATURE, METHOD_SIGNATURE and TYPE_SIGNATURE.
    sv - the visitor to which this adapter must delegate calls. May be null.
