# Package org.eclipse.jdt.debug.core

package org.eclipse.jdt.debug.core
Provides an implementation of a debug model based on JPDA (Java Platform Debug Architecture).

## Package Specification

This package provides a set of classes and interfaces that implement a debug model based on JPDA/JDI (Java Debug Interface). It provides a set of interfaces that extend the base set of debug element interfaces to provide access to Java specific attributes and behavior. This model defines and provides utilities for creating line breakpoints, method entry breakpoints, exception breakpoints, and field watchpoints.

Class
Description
IEvaluationRunnable
A runnable that represents one logical evaluation to be run in a target thread.
IJavaArray
A value referencing an array on a target VM.
IJavaArrayType
The type of an array on a Java debug target.
IJavaBreakpoint
A breakpoint specific to the Java debug model.
IJavaBreakpointListener
Provides event and error notification for Java breakpoints.
IJavaClassObject
An object referencing an instance of `java.lang.Class` on a target VM.
IJavaClassPrepareBreakpoint
A breakpoint that suspends execution when a class is prepared in a target VM.
IJavaClassType
The class of an object on a Java debug target.
IJavaDebugTarget
A Java virtual machine.
IJavaExceptionBreakpoint
A breakpoint that suspends execution when a corresponding exception is thrown in a target VM.
IJavaExceptionBreakpoint.SuspendOnRecurrenceStrategy
Constants for telling the debugger for each exception breakpoint how to handle multiple occurrences of the same exception instance, which can happen via re-throwing or multiple finally clauses in the call stack.
IJavaFieldVariable
A variable that contains the value of an instance or class variable.
IJavaHotCodeReplaceListener
Notification of hot code replace failure and success.
IJavaInterfaceType
An interface an object implements on a Java debug target.
IJavaLineBreakpoint
A breakpoint that suspends execution when a particular line of code is reached.
IJavaMethodBreakpoint
A method breakpoint suspends execution when a method is entered or exited.
IJavaMethodEntryBreakpoint
A method entry breakpoint suspends execution on the first executable line of a method when entered.
IJavaModifiers
Modifiers common to Java debug elements that have associated Java member declarations.
IJavaObject
A value referencing an object on a target VM.
IJavaPatternBreakpoint
Deprecated.
use `IJavaStratumLineBreakpoint` instead
IJavaPrimitiveValue
A primitive value on a Java debug target.
IJavaReferenceType
Represents the type of an object in a virtual machine - including classes, interfaces and array types.
IJavaStackFrame
A stack frame in a thread on a Java virtual machine.
IJavaStratumLineBreakpoint
A line breakpoint identified by its source file name and/or path, and stratum that it is relative to.
IJavaTargetPatternBreakpoint
A line breakpoint installed in types associated with a specific source file (based on source file name debug attribute) and whose fully qualified name matches a specified pattern per target.
IJavaThread
A thread in a Java virtual machine.
IJavaThreadGroup
Represents a thread group in the target VM.
IJavaType
The type of a value on a Java debug target - a primitive data type, class, interface, or array.
IJavaValue
An object, primitive data type, or array, on a Java virtual machine.
IJavaVariable
A local variable, field slot, or receiver (this) in a Java virtual machine.
IJavaWatchpoint
A breakpoint on a field.
JDIDebugModel
Provides utility methods for creating debug targets and breakpoints specific to the JDI debug model.
