Constructor Detail

SignatureReader

public SignatureReader(java.lang.String signature)

Constructs a SignatureReader for the given signature.

Parameters:

signature - A JavaTypeSignature, ClassSignature or MethodSignature.

Method Detail

accept

public void accept(SignatureVisitor signatureVistor)

Makes the given visitor visit the signature of this SignatureReader. This signature is the one specified in the constructor (see SignatureReader(java.lang.String)). This method is intended to be called on a SignatureReader that was created using a ClassSignature (such as the signature parameter of the ClassVisitor.visit(int, int, java.lang.String, java.lang.String, java.lang.String, java.lang.String[]) method) or a MethodSignature (such as the signature parameter of the ClassVisitor.visitMethod(int, java.lang.String, java.lang.String, java.lang.String, java.lang.String[]) method).

Parameters:

signatureVistor - the visitor that must visit this signature.

acceptType

public void acceptType(SignatureVisitor signatureVisitor)

Makes the given visitor visit the signature of this SignatureReader. This signature is the one specified in the constructor (see SignatureReader(java.lang.String)). This method is intended to be called on a SignatureReader that was created using a JavaTypeSignature, such as the signature parameter of the ClassVisitor.visitField(int, java.lang.String, java.lang.String, java.lang.String, java.lang.Object) or MethodVisitor.visitLocalVariable(java.lang.String, java.lang.String, java.lang.String, org.objectweb.asm.Label, org.objectweb.asm.Label, int) methods.

Parameters:

signatureVisitor - the visitor that must visit this signature.

parseType

private static int parseType(java.lang.String signature,
                             int startOffset,
                             SignatureVisitor signatureVisitor)

Parses a JavaTypeSignature and makes the given visitor visit it.

Parameters:

signature - a string containing the signature that must be parsed.

startOffset - index of the first character of the signature to parsed.

signatureVisitor - the visitor that must visit this signature.

Returns:

the index of the first character after the parsed signature.
