                                 EnhanceContext context)

Method Detail

className

public String className()

isLog

public boolean isLog(int level)

log

public void log(String msg)

isQueryBean

public boolean isQueryBean(String owner)

getClassAnnotationInfo

public AnnotationInfo getClassAnnotationInfo()

getInterfaceTransactionalInfo

public AnnotationInfo getInterfaceTransactionalInfo(String methodName,
                                                    String methodDesc)

Returns null if no matching (transactional) interface method was found.

visit

public void visit(int version,
                  int access,
                  String name,
                  String signature,
                  String superName,
                  String[] interfaces)

Visit the class with interfaces.

Overrides:

visit in class ClassVisitor

Parameters:

version - the class version. The minor version is stored in the 16 most significant bits, and the major version in the 16 least significant bits.

access - the class's access flags (see Opcodes). This parameter also indicates if the class is deprecated.

name - the internal name of the class (see Type.getInternalName()).

signature - the signature of this class. May be null if the class is not a generic one, and does not extend or implement generic classes or interfaces.

superName - the internal of name of the super class (see Type.getInternalName()). For interfaces, the super class is Object. May be null, but only for the Object class.

interfaces - the internal names of the class's interfaces (see Type.getInternalName()). May be null.

visitAnnotation

public AnnotationVisitor visitAnnotation(String desc,
                                         boolean visible)

Visit class level annotations.

Overrides:

visitAnnotation in class ClassVisitor

Parameters:

desc - the class descriptor of the annotation class.

visible - true if the annotation is visible at runtime.

Returns:

a visitor to visit the annotation values, or null if this visitor is not interested in visiting this annotation.

visitField

public FieldVisitor visitField(int access,
                               String name,
                               String desc,
                               String signature,
                               Object value)

Description copied from class: ClassVisitor

Visits a field of the class.

Overrides:

visitField in class ClassVisitor

Parameters:

access - the field's access flags (see Opcodes). This parameter also indicates if the field is synthetic and/or deprecated.

name - the field's name.

desc - the field's descriptor (see Type).

signature - the field's signature. May be null if the field's type does not use generic types.

value - the field's initial value. This parameter, which may be null if the field does not have an initial value, must be an Integer, a Float, a Long, a Double or a String (for int, float, long or String fields respectively). This parameter is only used for static fields. Its value is ignored for non static fields, which must be initialized through bytecode instructions in constructors or methods.

Returns:

a visitor to visit field annotations and attributes, or null if this class visitor is not interested in visiting these annotations and attributes.

visitMethod

public MethodVisitor visitMethod(int access,
                                 String name,
                                 String desc,
                                 String signature,
                                 String[] exceptions)

Visit the methods specifically looking for method level transactional annotations.

Overrides:

visitMethod in class ClassVisitor

Parameters:

access - the method's access flags (see Opcodes). This parameter also indicates if the method is synthetic and/or deprecated.

name - the method's name.

desc - the method's descriptor (see Type).

signature - the method's signature. May be null if the method parameters, return type and exceptions do not use generic types.

exceptions - the internal names of the method's exception classes (see Type.getInternalName()). May be null.

Returns:

an object to visit the byte code of the method, or null if this class visitor is not interested in visiting the code of this method.

visitEnd

public void visitEnd()

Description copied from class: ClassVisitor

Visits the end of the class. This method, which is the last one to be called, is used to inform the visitor that all the fields and methods of the class have been visited.

Overrides:

visitEnd in class ClassVisitor

createMethodKey

public TransactionalMethodKey createMethodKey(String methodName,
                                              String methodDesc,
                                              int profId)

Create and return the TransactionalMethodKey.

Takes into account the profiling mode (as per manifest) and explicit profileId.

isEnableProfileLocation

public boolean isEnableProfileLocation()

Return true if profile location enhancement is on.

isFinder

public boolean isFinder()

Return true if this enhancing class extends Ebean Finder.

putTxnLabel

public void putTxnLabel(int locationField,
                        String txLabel)

Set the transaction label for a given index.
