public final class ClassReader
extends AnnotatedReader

A Java class parser to make a ClassVisitor visit an existing class.

The Java type to be parsed is given in the form of a byte array conforming to the Java class file format. For each field and method encountered, the appropriate visit method of a given class visitor is called.

Constructor Details

ClassReader

public ClassReader(@NonNull
 byte[] code)

Initializes a new class reader with the given bytecode array for a classfile.

Method Details

getVersion

public int getVersion()

Returns the classfile version of the class being read.

getAccess

public int getAccess()

Returns the class's access flags.

getSuperName

@NonNull
public String getSuperName()

Returns the internal of name of the super class. For interfaces, the super class is Object.

getBytecode

@NonNull
public byte[] getBytecode()

Returns the bytecode array of the Java classfile that was read.

accept

public void accept(ClassVisitor visitor)

Makes the given visitor visit the Java class of this Class Reader.

readAttribute

@Nullable
protected Boolean readAttribute(@NonNull
 String attributeName)

Description copied from class: AnnotatedReader

Attempts to read the next attribute, provided it's one recognizable by the implementing subclass.

Specified by:

readAttribute in class AnnotatedReader

Parameters:

attributeName - the attribute name

Returns:

true if BytecodeReader.codeIndex is already pointing to the next attribute in the classfile, false or null otherwise; in the case of null, the current attribute was not yet identified, but is one of the more general ones ("RuntimeVisibleAnnotations", "Deprecated", or "Synthetic")

getBSMCodeIndex

public @NonNegative int getBSMCodeIndex(@NonNegative int bsmStartIndex)
