Eclipse JDT
Release 3.5

org.eclipse.jdt.debug.core
Class JDIDebugModel

java.lang.Object
  extended by 
org.eclipse.jdt.debug.core.JDIDebugModel

public class JDIDebugModel
extends Object

Provides utility methods for creating debug targets and breakpoints specific to the JDI debug model.

To provide access to behavior and information specific to the JDI debug model, a set of interfaces are defined which extend the base set of debug element interfaces. For example, IJavaStackFrame is declared to extend IStackFrame, and provides methods specific to this debug model. The specialized interfaces are also available as adapters from the debug elements generated from this model.

This class provides static utility methods only.

Restriction:
This class is not intended to be subclassed by clients.
Restriction:
This class is not intended to be instantiated by clients.

CoreException
Creates and returns a line breakpoint in the type with the given name, at the given line number. The marker associated with the breakpoint will be created on the specified resource. If a character range within the line is known, it may be specified by charStart/charEnd. If hitCount is > 0, the breakpoint will suspend execution when it is "hit" the specified number of times.

Parameters:
resource - the resource on which to create the associated breakpoint marker
typeName - the fully qualified name of the type the breakpoint is to be installed in. If the breakpoint is to be installed in an inner type, it is sufficient to provide the name of the top level enclosing type. If an inner class name is specified, it should be formatted as the associated class file name (i.e. with $). For example, example.SomeClass$InnerType, could be specified, but example.SomeClass is sufficient.
lineNumber - the lineNumber on which the breakpoint is set - line numbers are 1 based, associated with the source file in which the breakpoint is set
charStart - the first character index associated with the breakpoint, or -1 if unspecified, in the source file in which the breakpoint is set
charEnd - the last character index associated with the breakpoint, or -1 if unspecified, in the source file in which the breakpoint is set
hitCount - the number of times the breakpoint will be hit before suspending execution - 0 if it should always suspend
register - whether to add this breakpoint to the breakpoint manager
attributes - a map of client defined attributes that should be assigned to the underlying breakpoint marker on creation, or null if none.
Returns:
a line breakpoint
Throws:
CoreException - If this method fails. Reasons include:
  • Failure creating underlying marker. The exception's status contains the underlying exception responsible for the failure.

CoreException
Creates and returns a line breakpoint identified by its source file name and/or path, and stratum that it is relative to.

Parameters:
resource - the resource on which to create the associated breakpoint marker
stratum - the stratum in which the source name, source path and line number are relative, or null. If null or if the specified stratum is not defined for a type, the source name, source path and line number are relative to the type's default stratum.
sourceName - the simple name of the source file in which the breakpoint is set, or null. The breakpoint will install itself in classes that have a source file name debug attribute that matches this value in the specified stratum, and satisfies the class name pattern and source path attribute. When null, the source file name debug attribute is not considered.
sourcePath - the qualified source file name in which the breakpoint is set, or null. The breakpoint will install itself in classes that have a source file path in the specified stratum that matches this value, and satisfies the class name pattern and source name attribute. When null, the source path attribute is not considered.
classNamePattern - the class name pattern to which the breakpoint should be restricted, or null. The breakpoint will install itself in each type that matches this class name pattern, with a satisfying source name and source path. Patterns may begin or end with '*', which matches 0 or more characters. A pattern that does not contain a '*' is equivalent to a pattern ending in '*'. Specifying null, or an empty string is the equivalent to "*". Multiple patterns can be specified by delimiting the patterns with a comma - e.g. "x.y.z,a.b.c". When multiple patterns are specified, The breakpoint will install itself in each of the types that match any of the specified class pattern, with a satisfying source name and source path.
lineNumber - the lineNumber on which the breakpoint is set - line numbers are 1 based, associated with the source file (stratum) in which the breakpoint is set
charStart - the first character index associated with the breakpoint, or -1 if unspecified, in the source file in which the breakpoint is set
charEnd - the last character index associated with the breakpoint, or -1 if unspecified, in the source file in which the breakpoint is set
hitCount - the number of times the breakpoint will be hit before suspending execution - 0 if it should always suspend
register - whether to add this breakpoint to the breakpoint manager
attributes - a map of client defined attributes that should be assigned to the underlying breakpoint marker on creation, or null if none.
Returns:
a stratum breakpoint
Throws:
CoreException - If this method fails. Reasons include:
  • Failure creating underlying marker. The exception's status contains the underlying exception responsible for the failure.

CoreException
Creates and returns an exception breakpoint for an exception with the given name. The marker associated with the breakpoint will be created on the specified resource. Caught and uncaught specify where the exception should cause thread suspensions - that is, in caught and/or uncaught locations. Checked indicates if the given exception is a checked exception.

Parameters:
resource - the resource on which to create the associated breakpoint marker
exceptionName - the fully qualified name of the exception for which to create the breakpoint
caught - whether to suspend in caught locations
uncaught - whether to suspend in uncaught locations
checked - whether the exception is a checked exception (i.e. compiler detected)
register - whether to add this breakpoint to the breakpoint manager
attributes - a map of client defined attributes that should be assigned to the underlying breakpoint marker on creation or null if none.
Returns:
an exception breakpoint
Throws:
CoreException - If this method fails. Reasons include:
  • Failure creating underlying marker. The exception's status contains the underlying exception responsible for the failure.

CoreException
Creates and returns a watchpoint on a field with the given name in a type with the given name. The marker associated with the breakpoint will be created on the specified resource. If hitCount > 0, the breakpoint will suspend execution when it is "hit" the specified number of times.

Parameters:
resource - the resource on which to create the associated breakpoint marker
typeName - the fully qualified name of the type the breakpoint is to be installed in. If the breakpoint is to be installed in an inner type, it is sufficient to provide the name of the top level enclosing type. If an inner class name is specified, it should be formatted as the associated class file name (i.e. with $). For example, example.SomeClass$InnerType, could be specified, but example.SomeClass is sufficient.
fieldName - the name of the field on which to suspend (on access or modification)
lineNumber - the lineNumber on which the breakpoint is set - line numbers are 1 based, associated with the source file in which the breakpoint is set
charStart - the first character index associated with the breakpoint, or -1 if unspecified, in the source file in which the breakpoint is set
charEnd - the last character index associated with the breakpoint, or -1 if unspecified, in the source file in which the breakpoint is set
hitCount - the number of times the breakpoint will be hit before suspending execution - 0 if it should always suspend
register - whether to add this breakpoint to the breakpoint manager
attributes - a map of client defined attributes that should be assigned to the underlying breakpoint marker on creation, or null if none.
Returns:
a watchpoint
Throws:
CoreException - If this method fails. Reasons include:
  • Failure creating underlying marker. The CoreException's status contains the underlying exception responsible for the failure.
